DEVELOPER TOOLS

Less config.
More building.

Tools that get out of the way. We build the ones we needed and could not find: fast, opinionated, and designed to disappear into your workflow. Some are open source. Some are paid. All of them are honest about which.

THE LINE

Two tools, two jobs.

One keeps a failing command alive until it passes. The other keeps the flows your users depend on from ever breaking.

WAITLIST Paid service

Pass Line

The cheapest durable agentic end-to-end tester. Connect a repo and a URL. The agent proposes the flows that must never break, then keeps them green by turning failures into fix PRs.

  • Proposes the critical paths itself, you approve the list
  • Runs them on every deploy, in a real browser
  • A red flow becomes a pull request, not a Slack ping

OPEN SOURCE MIT · npm

Deadpool Runner

An ACP-powered command runner that streams script output, uses Codex to fix failures, and retries automatically with configurable limits. Scripts that will not stay dead.

  • Wrap any command: dpr -- npm test
  • On failure, an agent reads the error, patches the repo, reruns
  • Retry budget, custom prompts, config file, SDK

How we build tools

Opinionated defaults

Zero-config should actually work. We make the choices so you do not have to, and when you disagree, the escape hatches are clean and obvious.

Speed is a feature

If a tool makes you wait, it is broken. We benchmark obsessively and ship only when it is fast enough to forget it is there.

Honest about the model

Deadpool Runner is open source and always will be. Pass Line is a paid service because keeping browsers and agents running costs real money. No black boxes, no surprise pricing.
