Launch HN: Bullet (YC S26) – A High-Velocity Coding Agent

Version 1.3.28 B–001 | Available for macOS & Linux | Private Beta: Free Access

🚀 Performance Benchmark

Bullet isn't just fast; it's precise. It currently achieves a score of: SWE-bench Verified=95.8%\text{SWE-bench Verified} = 95.8\%SWE-bench Verified=95.8% [Read the full results →\rightarrow→]


The Core Philosophy: Speed by Design

Bullet is engineered to eliminate the gap between your thought process and the code's execution. It routes, searches, and executes with a singular focus: maintaining your momentum.

01. The Problem: Latency≈Friction\text{Latency} \approx \text{Friction}Latency≈Friction

Your creative flow moves rapidly, but the tools supporting it have historically been unnecessarily heavy sluggish. Bullet removes the "dead time" that kills productivity.

02. The Bullet Protocols

Protocol 01: Route & Escalate

Bullet doesn't use a sledgehammer for every nail. It dynamically assigns the most efficient model based on the difficulty of the task.

Protocol 02: Search & Acquire

Instead of wasting resources embedding an entire repository, Bullet uses targeted acquisition to find exactly what it needs.

Target QueryFile PathRelevance Score
auth middlewaresrc/router.ts94.2%
auth middlewaresrc/auth.ts88.7%

Context acquired: 08% of total repo.

Protocol 03: Parallel Execution

Bullet refuses to queue operations that can run simultaneously. It intercepts stuck loops and duplicate calls instantly.

  • Simultaneous Operations:
    • Search∥Read∥Verify\text{Search} \parallel \text{Read} \parallel \text{Verify}Search∥Read∥Verify
  • Elapsed Time: 00:02.31

The Goal: Momentum, not magic. No more waiting for the agent to "think" through linear steps that could be handled in parallel.


03. Field Test

04. Get Started

Bullet is a CLI-first tool. There is no GUI to slow you down.

System Requirements:

  • macOS or Linux
  • Node.js 18+
  • No API key required to start (Free)

Installation:

# Install the Bullet CLI globally
npm install -g @trybullet/cli

# Launch the agent
bullet

05. Founders' Note

"Bullet was born out of pure frustration. While using Claude Code daily, we realized that even the most capable models were being throttled by slow, clunky machinery. We started this as a passion project to prove that we could route simple tasks faster, read only the essential code, execute tools in parallel, and kill infinite loops before they waste a single second."
