Keystroke

Build internal AI agents as real TypeScript, ship them to your team

What it is

Keystroke is an open-source, code-first platform for building internal AI agents and workflows. You write agents and workflows as ordinary TypeScript in your own repo, tested with Vitest, and Keystroke deploys them to a hosted web app with a chat UI, credentials, integrations, and run history built in. It's aimed at developer teams who found visual automation tools hard to maintain at scale but didn't want to build their own deployment plumbing for a code-first agent either.

What you get free vs paid

Verdict

Where it wins and loses

Pros

Fully open source on GitHub, so you can read the framework or self-host it instead of paying
Agents and workflows are real TypeScript with Zod schemas and Vitest tests, not JSON blobs in a visual builder
Deployed agents get a working chat UI, credential management, and run history automatically, no separate front-end to build
Backed by Y Combinator (W24 batch) with public docs and an active Discord
$20 in free credits to start, no card required during the open alpha

Cons

Still in open alpha, so expect breaking changes and rough edges
Requires comfort writing TypeScript; it's not a no-code tool like n8n or Zapier
Free credits run out, and ongoing hosted pricing beyond the alpha isn't fully settled yet
Small young team, so support depth and long-term roadmap are unproven

Worth trying if your team already writes TypeScript and has outgrown a visual automation tool's JSON blobs. Skip it if you want a no-code builder or need a stable, mature platform today.
