OpenCode was the first open source agent I used, and my main workhorse after experimenting briefly with Claude Code and realizing the potential of agentic coding. Due to that, and because it's a popular an open source alternative, I want to be able to recommend it and be enthusiastic about it. The problem for me is that the development practices of the people that are working on it are suboptimal at best; they're constantly releasing at an extremely high cadence, where they don't even spend the time to test or fix things (or even build a proper list of changes for each release), and they add, remove, refine, change, fix, and break features constantly at that accelerated pace.
More than that, it's an extremely large and complex TypeScript code base — probably larger and more complex than it needs to be — and (partly as a result) it's fairly resource inefficient (often uses 1GB of RAM or more. For a TUI).
On top of that, at least I personally find the TUI to be overbearing and a little bit buggy, and the agent to be so full of features that I don't really need — also mildly buggy — that it sort of becomes hard to use and remember how everything is supposed to work and interact.

I am more concerned about their, umm, gallant approach to security. Not only that OpenCode is permissive by default in what it is allowed to do, but that it apparently tries to pull its config from the web (provider-based URL) by default [1]. There is also this open GitHub issue [2], which I find quite concerning (worst case, it's an RCE vulnerability).
RCE is exactly the feature of coding agents. I'm happy with it that I don't need to launch OpenCode with --dangerously-skip every time.

this is what i notice with openclaw as well. there have been releases where they break production features. unfortunately this is what happens when code becomes a commidity, everyone thinks that shipping fast is the moat but at the expense of suboptimality since they know a fix can be implemented quickly on the next release.

Openclaw has 20k commits, almost 700k lines of code, and it is only four months old. I feel confident that that sort of code base would have a no coherent architecture at all, and also that no human has a good mental model of how the various subsystems interact.
I’m sure we’ll all learn a lot from these early days of agentic coding.

Probably all describe problems stem from the developers using agent coding; including using TypeScript, since these tools are usually more familiar with Js/Js adjacent web development languages.
By blks 2 hours ago
Perhaps the use of coding agents may have encouraged this behavior, but it is perfectly possible to do the opposite with agents as well — for instance, to use agents to make it easier to set up and maintain a good testing scaffold for TUI stuff, a comprehensive test suite top to bottom, in a way maintainers may not have had the time/energy/interest to do before, or to rewrite in a faster and more resource efficient language that you may find more verbose, be less familiar with, or find annoying to write — and nothing is forcing them to release as often as they are, instead of just having a high commit velocity. I've personally found AIs to be just as good at Go or Rust as TypeScript, perhaps better, as well, so I don't think there was anything forcing them to go with TypeScript. I think they're just somewhat irresponsible devs.

I recently listened to this episode from the Claude Code creator (here is the video version: https://www.youtube.com/watch?v=PQU9o_5rHC4) and it sounded like their development process was somewhat similar - he said something like their entire codebase has 100% churn every 6 months. But I would assume they have a more professional software delivery process.
I would (incorrectly) assume that a product like this would be heavily tested via AI - why not? AI should be writing all the code, so why would the humans not invest in and require extreme levels of testing since AI is really good at that?

I mean, I'm slowly trying to learn lightweight formal methods (i.e. what stuff like Alloy or Quint do), behavior driven development, more advanced testing systems for UIs, red-green TDD, etc, which I never bothered to learn as much before, precisely because they can handle the boilerplate aspects of these things, so I can focus on specifying the core features or properties I need for the system, or thinking through the behavior, information flow, and architecture of the system, and it can translate that into machine-verifiable stuff, so that my code is more reliable! I'm very early on that path, though. It's hard!

Interesting you say this because I'd say the opposite is true historically, especially in the systems software community and among older folks. "Do one thing and do it well" seems to be the prevailing mindset behind many foundational tools. I think this why so many are/were irked by systemd. On the other hand newer tools that are more heavily marketed and often have some commercial angle seem to be in a perpetual state of tacking on new features in lieu of refining their raison d'etre.

Big +1 to Pi[1]. The simplicity makes it really easy to extend yourself too, so at this point I have a pretty nice little setup that's very specific to my personal workflows. The monorepo for the project also has other nice utilities like a solid agent SDK. I also use other tools like Claude Code for "serious" work, but I do find myself reaching for Pi more consistently as I've gotten more confident with my setup.

Isn't this pretty much the standard across projects that make heavy use of AI code generation?
Using AI to generate all your code only really makes sense if you prioritize shipping features as fast as possible over the quality, stability and efficiency of the code, because that's the only case in which the actual act of writing code is the bottleneck.
By bakugo 2 hours ago
I don't think that's true at all. As I said, in a response to another person blaming it on agentic coding above, there are a very large number of ways to use coding agents to make your programs faster, more efficient, more reliable, and more refined that also benefit from agents making the code writing research, data piping, and refactoring process quicker and less exhausting. For instance, by helping you set up testing scaffolding, handling the boilerplate around tests while you specify some example features or properties you want to test and expands them, rewriting into a more efficient language, large-scale refactors to use better data structures or architectures, or allowing you to use a more efficient or reliable language that you don't know as well or find to have too much boilerplate or compiler annoyance to otherwise deal with yourself. Then there are sort of higher level more phenomenological or subjective benefits, such as helping you focus on the system architecture and data flow, and only zoom in on particular algorithms or areas of the code base that are specifically relevant, instead of forever getting lost in the weeds of thinking about specific syntax and compiler errors or looking up a bunch of API documentation that isn't super important for the core of what you're trying to do and so on.
Personally, I find this idea that "coding isn't the bottleneck" completely preposterous. Getting all of the API documentation, the syntax, organizing and typing out all of the text, finding the correct places in the code base and understanding the code base in general, dealing with silly compiler errors and type errors, writing a ton of error handling, dealing with the inevitable and inoraticable boilerplate of programming (unless you're one of those people that believe macros are actually a good idea and would meaningfully solve this), all are a regular and substantial occurrence, even if you aren't writing thousands of lines of code a day. And you need to write code in order to be able to get a sense for the limitations of the technology you're using and the shape of the problem you're dealing with in order to then come up with and iterate on a better architecture or approach to the problem. And you need to see your program running in order to evaluate whether it's functionality and design a satisfactory and then to iterate on that. So coding is actually the upfront costs that you need to pay in order to and even start properly thinking about a problem. So being able to get a prototype out quickly is very important. Also, I find it hard to believe that you've never been in a situation where you wanted to make a simple change or refactor that would have resulted in needing to update 15 different call sites to do properly in a way that was just slightly variable enough or complex enough that editor macros or IDE refactoring capabilities wouldn't be capable of.
That's not to mention the fact that if agentic coding can make deploying faster, then it can also make deploying the same amount at the same cadence easier and more relaxing.

By oldestofsports 4 hours ago
With Anthropic, you either pay per token with an API key (expensive), or use their subscription, but only with the tools that they provide you - Claude, Claude Cowork and Claude Code (both GUI and CLI variants). Individuals generally get to use the subscriptions, companies, especially the ones building services on top of their models, are expected to pay per token. Same applies to various third party tools.
The belief is that the subscriptions are subsidized by them (or just heavily cut into profit margins) so for whatever reason they're trying to maintain control over the harness - maybe to gather more usage analytics and gain an edge over competitors and improve their models better to work with it, or perhaps to route certain requests to Haiku or Sonnet instead of using Opus for everything, to cut down on the compute.
Given the ample usage limits, I personally just use Claude Code now with their 100 USD per month subscription because it gives me the best value - kind of sucks that they won't support other harnesses though (especially custom GUIs for managing parallel tasks/projects). OpenCode never worked well for me on Windows though, also used Codex and Gemini CLI.
By KronisLV 3 hours ago
>or perhaps to route certain requests to Haiku or Sonnet instead of using Opus for everything, to cut down on the compute
You can point Claude Code at a local inference server (e.g. llama.cpp, vLLM) and see which model names it sends each request to. It's not hard to do a MITM against it either. Claude Code does send some requests to Haiku, but not the ones you're making with whatever model you have it set to - these are tool result processing requests, conversation summary / title generation requests, etc - low complexity background stuff.
Now, Anthropic could simply take requests to their Opus model and internally route them to Sonnet on the server side, but then it wouldn't really matter which harness was used or what the client requests anyway, as this would be happening server-side.
By anonym29 3 hours ago
Anthropic's model deployments for Claude Code are likely optimized for Claude Code. I wouldn't be surprised if they had optimizations like sharing of system prompt KV-cache across users, or a speculative execution model specifically fine-tuned for the way Claude Code does tool calls.
When setting your token limits, their economics calculations likely assume that those optimizations are going to work. If you're using a different agent, you're basically underpaying for your tokens.

Some clients have made it simple to use your subscription key with them and they are getting cease and desist letters.

By quietsegfault 3 hours ago
Sure happy to share. It’s been trial and error, but I’ve learned that for agents to reliably ship a large feature or refactor, I need a good spec (functional acceptance criteria) and I need a good plan for sequencing the work.
The big expensive models are great at planning tasks and reviewing the implementation of a task. They can better spot potential gotchas, performance or security gaps, subtle logic and nuance that cheaper models fail to notice.
The small cheap models are actually great (and fast) at generating decent code if they have the right direction up front.
So I do all the spec writing myself (with some LLM assistance), and I hand it to a Supervisor agent who coordinates between subagents. Plan -> implement -> review -> repeat until the planner says “all done”.
I switch up my models all the time (actively experimenting) but today I was using GPT 5.4 for review and planning, costing me about $0.4-$1 for a good sized task, and Kimi for implementation. Sometimes my spec takes 4-5 review loops and the cost can add up over an 8 hour day. Still cheaper than Claude Max (for now, barely).
Each agent retains a fairly small context window which seems to keep costs down and improves output. Full context can be catastrophic for some models.
As for the spec writing, this is the fun part for me, and I’ve been obsessing over this process, and the process of tracking acceptance criteria and keeping my agents aligned to it. I have a toolkit cooking, you can find in my comment history (aiming to open source it this week).
I love OpenCode! I wrote a plugin that adds two tools: prune and retrieve. Prune lets the LLM select messages to remove from the conversation and replace with a summary and key terms. The retrieve tool lets it get those original messages back in case they're needed. I've been livestreaming the development and using it on side projects to make sure it's actually effective... And it turns out it really is! It feels like working with an infinite context window.
Pi is refreshingly minimal in terms of system prompts, but still works really well and that makes me wonder whether other harnesses are overdoing. Look at OpenCode's prompts, for instance - long, mostly based on feels and IMO unnecessary. I would've liked to just overwrite OC's system prompts with Pi's (to get other features that Pi doesn't have) but that isn't possible today (without maintaining a custom fork)

One thing that makes coding agents really useful is structured data access via MCP servers. Instead of the agent trying to scrape a webpage to understand your project's context, you give it a direct API to query structured data from 9+ sources (GitHub repos, Stack Overflow questions, arXiv papers, npm packages).
The biggest bottleneck I've seen isn't the coding — it's the agent not having enough context about the ecosystem it's working in.

You can start a service via `opencode serve`, it can be accessed from anywhere and has great experience on mobile except a few bugs. It's a really good way to work with your agents remotely, goes really well with TailScale.
The WebUI that they have can connect to multiple OpenCode backends at once, so you may use multiple VPS-es for various projects you have and control all of them from a single place.
Lastly, there's a desktop app, but TBH I find it redundant when WebUI has everything needed.
Make no mistakes though, it's not a perfect tool, my gripes with it:
- There are random bugs with loading/restoring state of the session
- Model/Provider selection switch across sessions/projects is often annoying
- I had a bug making Sonnet/Opus unusable from mobile phone because phone's clock was 150ms ahead of laptop's (ID generation)
- Sometimes agent get randomly stuck. It especially sucks for long/nested sessions
- WebUI on laptop just completely forgot all the projects at
one day
- `opencode serve` doesn't pick up new skills automatically, it needs to be restarted

Yeah, support the company that promised to help your government illegally mass surveil and mass kill people, because they support a use case slightly better than the non-mass-murdering option.
By hungryhobbit 3 hours ago
Both of them promised to help their government illegally mass surveil and mass kill people. One of them just didn't want it done to US citizens.
I'm not a US citizen, so both companies are the same, as far as I'm concerned.
By stavros 3 hours ago
You are absolutely correct that both are evil ... as are most corporations.
Still, I feel like "will commit illegal mass murder against their own citizens" is a significant enough degree more evil. I think lots of corporations will help their government murder citizens of other countries, but very few would go so far as to agree to murder their own (fellow) citizens ... just to get a juicy contract.
By hungryhobbit 3 hours ago
I see your viewpoint but, to me, "both will happily murder you but one is better because they won't murder ME!" isn't very compelling. Like, I get it, but also it changes nothing for me. They're both bad.
By stavros 3 hours ago
It's not about "won't murder me" it's about "won't murder their own tribe". Humans are very tribal creatures, and we have all sorts of built-in societal taboos about betraying our tribe.
We also have taboos against betraying/murdering/whatever people of other tribes, but those taboos are much weaker and get relaxed sometimes (eg. in war). My point is, it takes significantly more anti-social (ie. evil) behavior to betray your own tribe, in the deepest way possible, than it does to do horrible things to other tribes.
This is just as much true for Russians murdering Ukranians as Ukranians murdering Russians, or any other conflict group: almost all Russians would consider a Russian who helps kill Russians to be more evil than a Russian who kills Ukranians (and vice versa).

watching trump get elected twice; you can see why americanos have no problemos with mental backflips when choosing.
But you're still choosing evil when you could try local models
You're right, Anthropic shouldn't have even taken a moral stance here at all. They should have just gone full send and allowed everything, because there will never be satisfying some people. Why even try?

By polski-g 2 hours ago
isn't this the one with default-on need code change to turn off telemetry?
You can scroll down literally two messages in the Github issue you linked:
> there isnt any telemetry, the open telemetry thing is if you want to get spans like the ai sdk has spans to track tokens and stuff but we dont send them anywhere and they arent enabled either
> most likely these requests are for models.dev (our models api which allows us to update the models list without needing new releases)

Things that make an an OpenCode fanboy
1. OpenCode source code is even more awesome. I have learned so much from the way they have organized tools, agents, settings and prompts.
2. models.dev is an amazing free resource of LLM endpoints these guys have put together
3. OpenCode Zen almost always has a FREE coding model that you can use for all kinds of work. I recently used the free tier to organize and rename all my documents.

Honestly I was a Claude code only guy for a while. I switched to opencode and I’m not going back.
IMO, the web UI is a killer feature - it’s got just enough to be an agent manager - without any fluff. I run it on my remote VMs and connect over HTTP.
OpenCode, by reason of plugins alone, is better than all of them.
By polski-g 2 hours ago
I feel like Anthropic really need to fork this for Claude Code or something. The render bugs in Claude Code drive me nuts.

If I wanted to switch from Claude Code to this - what openai model is comparable to opus 4.6? And is it the same speed or slower/faster? Thank you!
By sergiotapia 4 hours ago
GPT 5.4 has been the winner this week. Last week Opus 4.6. You can use both in OpenCode.
By pimeys 4 hours ago
How does it compare to using GPT 5.4 inside Codex?
By arbuge 4 hours ago
I used Codex for a long time. It's definitely better than Claude Code due to being open source, but opencode is nicer to use. Good hotkeys, plan/build modes, fast and easy model switching, good mcp support. Supports skills, is not the fastest but good enough.
By pimeys 2 hours ago
Well not anymore with Claude pro…
By nxpnsv 4 hours ago
If you want faster, anything running on a Cerebras machine will do.
Never tried it for much coding though.

opus/sonnet 4.6 can be used in opencode with a github copilot subscription
I don't see why not. It's just using the Github Copilot API.

Just remember, OpenCode is sending telemetry to their own servers, even when you're using your own locally hosted models. There are no environment variables, flags, or other configuration options to disable this behavior.¹
At least you can easily turn off telemetry in Claude Code - just set CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC to 1.
You can use Claude Code with llama.cpp and vLLM, too right out of the box with no additional software necessary, just point ANTHROPIC_BASE_URL at your inference server of choice, with any value in ANTHROPIC_API_KEY.
Some people think that Anthropic could disable this at any time, but that's not really true - you can disable automatic updates and back up and reuse native Claude Code binaries, ensuring Anthropic cannot change your existing local Claude Code binary's behavior.
With that said, I like the idea of an open source TUI agent that won't spy on me without my consent and no way to disable it much better than a closed source TUI agent that I can effectively neuter telemetry on, but sadly, OpenCode is not the former. It's just another piece of VC-funded spyware that's destined for enshittification.
Are you sure that endpoint is sending all traffic to opencode? I'm not familiar with Hono but it looks like a catch all route if none of the above match and is used to serve the front-end web interface?
By debazel 3 hours ago
You are correct, it is indeed a route for the web interface
By flexagoon 3 hours ago

By anonym29 3 hours ago
They don't. That is just the route for their WebUI, which is completely optional.

I've point thought about making things that just send garbage to any data collecting service.

Sadly Antropic have blocked the usage of claude on it.
By delduca 2 hours ago
No, they haven’t. You can use claude like any other model via API, you just can’t reuse your subscription token.
