The CLI tool that writes code for you

Chat with Codebuff to edit your codebase. It's a coding agent that can iterate and run terminal commands, just like a real engineer! We are going up-market from Cursor, starting at a $49/mo price point. Codebuff chooses files to read automatically on each message, which improves its awareness of your codebase and saves you time. It has full access to your terminal — Codebuff can run terminal commands to install packages, run tests, check for type errors, etc. It's the most powerful coding agent on the market that also happens to be the easiest to use. Codebuff is an engineer working for you. Run `npm install -g codebuff` to get started.

Active Founders

James Grugett, Founder

I'm building Codebuff — the CLI tool that writes code for you. Previously, I founded Manifold Markets, a site with 150,000 user-created prediction markets that gets millions of views per month. I'll be applying lessons learned from growing a consumer app for nerds (Manifold) to growing Codebuff, a dev tool for software nerds. I bring passion and intensity to my work. With Codebuff, I've jumped into a new field, AI code generation, and built something state of the art within a couple months.

Brandon Chen, Founder

I've worked at YC companies all of my software engineering career (Kuna W14, Virtually S20)! Excited to take part on a founder level. My cofounder James and I are building a coding agent that lives in your terminal – the simplest and most accessible way to get your software projects built!

Manicode: Make your terminal write code for you

See original launch post ›

Manicode is a CLI-based coding agent – invoke it in your Terminal and ask it to write code for you. We launched on BookFace last week and got 500 downloads and 60+ upvotes!

It’s a Cursor alternative that’s simpler and frequently performs better. Try it out:

npm install -g manicode

What people are saying

Fewer clicks, more codebase context

Manicode is different from all the other coding agents, we swear!

It chooses files to read automatically on each message — unlike Cursor’s composer feature. This saves you time and makes Manicode respond more comprehensively.
It takes 0 clicks — type your instructions and Manicode will edit your files directly. It's simple and fast. Theoretically, you can do all your development by just chatting with it!
It has full access to your existing tools, scripts, and packages — Manicode can install packages, run terminal commands and tests, etc. Whatever awk/grep/pip install stuff you used to do, Manicode can do it for you instead!
It is portable to any development environment — no lock-in here! Feel free to bring your IDE: VSCode, Cursor, Vim, Emacs, Replit, or plain text editor (if you’re a monster).
We don’t store your codebase — we just pass individual files along to OpenAI and Anthropic as is necessary to generate code. We didn’t even have a database until a couple weeks ago!

Manicode can write code for every tech stack – we know because we’ve built software from full-stack web apps to IoT device firmware.
