YC F24's @ManicodeAI is a CLI tool that writes code for you. It uses your codebase as context and edits your files automatically. Try it out: `npm i -g manicode` ycombinator.com/launches/M2Q-m… Congrats on the launch, James Grugett and Brandon Chen!

Codebuff Launch Week — Day 2 Introducing "codebuff --max" mode, for insanely high quality results! It's an eerie hybrid of Gemini 2.5 Pro & Sonnet 3.6 that is both good at planning and taking action through tool calls. Drop it into any project and watch it build 🏗️

Codebuff Launch Week — Day 3 Introducing "codebuff --lite" mode ⚡️, for faster & lower cost results! This uses Gemini 2.5 Flash Thinking, which is currently the best bang-for-your-buck model. We're fast becoming "Gemini Code" for relying on so many Gemini models 😂

Lite mode compared to normal mode: - 1/5th the price - 4x speed And it works well for simple requests! Fun fact: As of yesterday, we were still using Claude Haiku for our --lite mode. Flash 2.5 is a major upgrade to say the least!

Codebuff 少し試したが一番賢そう! AIを活用してコードベースを深く理解し、ターミナルから直接開発を加速できる次世代の開発支援ツール codebuff.com/referrals/ref-… Cursur, Windsurf, Cline などでVibe codingしてる人は無料お試しして欲しい。ClaudeCodeに近いのかな。それでよりコスパ良く賢い。

Codebuff Launch Week — Day 4 👏 Your coding agent should manage your dev processes (e.g. npm run dev)!👏 Shipped today: Type "init" in codebuff to initialize your project! Generates: - an overview of your project (knowledge .md) - a config file for bg processes (codebuff.json)

Codebuff Launch Week — Day 5, final day 🔥 Introducing our custom model for picking files! Codebuff picks a dozen files relevant to your prompt in the first 2 seconds. We shipped a new model for this, and it's twice as good at matching a golden dataset as before!

This is huge, as context is the most important input to a coding agent. If we can accurately pick files in two seconds, that could save the agent minutes of searching the codebase, and lots of $$$. Here you can see the total loss decreasing over training.

We beat Claude Code in our evals: 61% to 53%. Yes, evals are actually important haha And now we’re open-sourcing our entire codebase and launching an agent framework! Now you can build custom agents for your project and get better results 🔥

Codebuff Launch Day 2: Let’s build a state-of-the-art Code Reviewer agent! Crazy stuff: - a tree of 15 thinker agents - running in parallel - using 3 different models - to produce the ultimate code review! Run it now yourself: codebuff --agent codebuff/[email protected]

Codebuff Launch Day 3 Users want to know: Why did we go open source? What's our strategy? And also: What's the deal with creating our own new benchmark to show we're ahead of Claude Code 😂

Codebuff Launch Week Day 4(ish): the Codebuff SDK Now Codebuff runs in any environment, not just the CLI. Your custom agents 🤝 SDK You get power, flexibility and ease of use. We're in the age of truly personal software now. Check out this Codebuff-powered web app I built:

Announcing the Agent Store! It's npm for agents: - Publish specialized agents - Run them by CLI or SDK - Compose them to build higher level agents This is the end game for agents 🧠

.Relace has raised $23M to build the rails for AI code generation. This round is led by a16z, with participation from Matrix and Y Combinator. LLMs have proven they can write code—but scaling that code into production still needs better infrastructure. Relace is
