Hi HN, excited to be sharing this with you guys today.

TL;DR: Bullet is a fast coding agent.

At our company, we were burning hours waiting on agent runs. The models weren’t the problem. The agent loops around them were slow (unnecessary planning, oversized context, repeated searches, and serial tool calls).

So we built Bullet as a passion project, the goal being to help you iterate faster, without giving up quality: - It automatically selects the model and reasoning level for each prompt. - It runs independent searches, reads, and commands in parallel. - It uses targeted code search instead of embedding the entire repository. - It works with your Claude Code or Codex subscription, OpenAI/Anthropic/xAI API keys, or an on-device model with no key.

Claude Code and Codex each center on their own model ecosystem. OpenCode gives you many models, but largely leaves model selection and configuration to you. Bullet sits above the models. Connect what you already pay for, then let Bullet choose the fastest path for every task.

On SWE-bench Verified, Bullet resolved 479/500 issues (95.8%, top 3 on the leaderboard) in one attempt, averaging 119 seconds per task (35–67% faster than mini-SWE-agent + Fable/Sol). Full results and methodology here: https://www.codewithbullet.com/blog/benchmark-results.html

We would love honest feedback on the product! It takes less than a minute to download and set up. We’d love to hear what you like about Bullet, and what sucks. The Mac app DMG release is on our website: https://www.codewithbullet.com/

P.S: we hid a code on the website, see if you can unlock the secret page at the footer (all built with Bullet) :) https://youtu.be/34wfiSoSw4Q

Interesting. I tried it with two real-life tasks that I usually would use Claude Code for (I prefer using it with the VSCode extension, not CLI).

1. First thing I noticed was the lack of autocompletion when entering @<filename> (or #<filename> with Github Copilot). Makes it really difficult to talk about files, since I don't always remember the full name. Had to go to VSCode to find it.

2. I assume, even though I selected Claude, it doesn't read CLAUDE.md? Does it have an equivalent? It had trouble navigating my repository. Pointing it to CLAUDE.md in the prompt fixed it, though.

3. For the second task, it created a plan (without me asking for one) and let me approve it. But then it marked the whole plan completed in the first few seconds, except the last item, before it wrote a single line of code. Or execute anything (the plan included what to edit, and what to test/run).

4. The generated code was fine for both tasks. The first one had about 20 changed lines, and the second ~100 lines + 300 lines of tests. It was very thorough in testing its changes, like the latest versions of Claude Code.

5. The bad part: implementing the plan for the 100 LOC change took about 13 minutes (unfortunately it doesn't show the exact duration when finished; it was at >100 tasks and over 770s). To compare, I stashed the changes, tried it on Claude Code with the same prompt, default model (Opus 5), auto mode. It did not create a plan and finished the task in 12 minutes. Claude's code was a bit simpler, and I prefer it over Bullet's by a small margin.

Thanks for the detailed feedback, this was really valuable.

We fixed file autocomplete, automatic CLAUDE.md loading for Claude subscription sessions, and the plan issues. Plans now only appear when requested, and progress only updates after the related work has actually been done.

Your comparison with Claude Code is fair. Speed remains something we're trying to optimize outside of benchmarks, and long running tasks with plans seems to be something we need to improve. We're actively working on more optimization to latency and unnecessary model calls.

Thanks again for the comment and if you could try the latest build when you have time, would love to hear your thoughts again!
