Show HN: 1Code – Open-source Cursor-like UI for Claude Code
Hi, we're Sergey and Serafim. We've been building dev tools at 21st.dev and recently open-sourced 1Code (https://1code.dev), a local UI for Claude Code.Here's a video of the product: https://www.youtube.com/watch?v=Sgk9Z-nAjC0Claude Code has been our go-to for 4 months. When Opus 4.5 dropped, parallel agents stopped needing so much babysitting. We started trusting it with more: building features end to end, adding tests, refactors. Stuff you'd normally hand off to a developer. We started running 3-4 at once. Then the CLI became annoying: too many terminals, hard to track what's where, diffs scattered everywhere.So we built 1Code.dev, an app to run your Claude Code agents in parallel that works on Mac and Web. On Mac: run locally, with or without worktrees. On Web: run in remote sandboxes with live previews of your app, mobile included, so you can check on agents from anywhere. Running multiple Claude Codes in parallel dramatically sped up how we build features.What’s next: Bug bot for identifying issues based on your changes; QA Agent, that checks that new features don't break anything; Adding OpenCode, Codex, other models and coding agents. API for starting Claude Codes in remote sandboxes.Try it out! We're open-source, so you can just bun build it. If you want something hosted, Pro ($20/mo) gives you web with live browser previews hosted on remote sandboxes. We’re also working on API access for running Claude Code sessions programmatically.We'd love to hear your feedback!

I hope the business model works out for you, but I doubt the price is justified.
Also a better link is: https://1code.dev/
The repo doesn't have screenshots, so you might loose traffic just because of that.
Nevertheless, I'll try it out - looks nice!
On pricing: honestly, the paid tier is less about monetization right now and more about signal. People who pay are the ones who really want this to work, and we want to build for them first. It helps us focus.

Honestly I am pretty frugal usually but respect. I think I read something like this either in some VC idea where people will intentionally raise prices in the start to see if their market is fit as you say (or perhaps I am butchering it, but you put it out wonderfully)
I just hope that in the end, you guys become competitive to things like exe.dev which is what I currently use (for completely free mind you but its in alpha version) but it provides an agent shelly with the web in a sandbox and I think that they are gonna focus on being more competitive in the market and there are multiple of options right now
Though just now I saw that 1code.dev is an YC backed startup and um, being honest, I have just less faith in YC backed/VC funded startups unless proven otherwise because VC requires profits so they might be incentivized to keep the pricing on the upper side of things and not change as you mention
I am not exactly sure how things would go for your product and I am unable to get a clear visual understanding of what you are trying to achieve but I feel like there are some things which you can do to solve it as the GP said
Basically please dont get enshittified in the end.

nothing specifically against vscode/electron/atom. i did use atom 10 years ago, then started sublime text 2, since then, it has been really hard to beat sublime text. the speed and rendering of sublime is much better.
i also have been using zed, which can be considered cloud-code ui too in certain terms, zed is quite more resource-intensive than the sublime and feels higher latency. (possibly because I use frosty-transparent theme...)
Zed is really snappy. It's kind of my go-to editor for most things.
I think this is a lot of "I don't like Typescript/Javascript for serious things" or "Electron sucks" posturing rather than an actual tangible difference.
I’m all for new, better tools and will probably test this out over the weekend to see if the interface is more usable than Claude’s. Just curious if there’s anything you’re particularly excited about compared to the official release.
So we decided to build a tool that WE would actually use, and once we succeeded with that, we open-sourced it. Since then we've received a lot of feedback on where to take this product - some use cases Anthropic will probably never do, like integrating Codex or adding other z.ai GLM subscription.
We're just trying to ship something we use ourselves, and maybe it could be useful to others, and see where it goes.
instead, an old-school arrow/pointer (or pointer trails like its '98!) would be nicer.
1. Absolutely nothing can be sent off-site
2. All AI API requests must go through our custom gateway (we've got deals with all the major AI providers, and I think that even involves a degree of isolated hosting in specific approved cloud environments)
While $20/mo feels a bit weird for an app that doesn't rely on its own cloud service, I'd subscribe right now just because I do "really want this to work".
Beyond that, we're working on API & integrations - connecting Sentry so an agent can automatically open a PR to fix an issue, or triggering Claude Codes directly from @ mentioning in GitHub/Slack/Linear.
>Yes, 1Code works with your Claude Pro or Max subscription. Sign in with your Anthropic account and use your existing subscription. We charge separately for the 1Code app.
Is this even after the recent events; Anthropic banning 3rd-party access to the Claude Pro/Max subscriptions and only allowing API access? Tool is nice but most certainly not* 800$ nice.
*Based on heavy Claude Max users here, the people that will be running 3-4 agents, saying API would've cost them $1k+.
Some other tools (like OpenCode) made direct API calls while impersonating Claude Code - that approach got banned. We're not doing that.
If you really want a 'different' UI thats unlike VSCode or Cursor already, I'd genuinely recommend checking out almost any other tool that pairs with CC.
And a "max" subscription for $200/m??? It makes no sense. It's not because LLM making companies have plans at $200 that any company should make a $200/m plan.
Even as a technical person, I remember my transition from Cursor to Claude Code CLI being rough. Maybe 1Code could be a way to get the best of both worlds, power of claude code and UX of Cursor
