Private beta — waitlist open

APIs change.
Your code
stays fixed.

Zenik watches the APIs your product depends on. When a provider ships a breaking change, the fix is written inside your own CI and arrives as a pull request. You review the diff. You merge. You move on.

How it works

Detect. Fix. Review.

You learn about breaking changes from incidents. Zenik learns about them from the source — and the fix shows up in your own CI before the incident happens.

01 / Detect

Zenik watches the providers

Zenik diffs every new provider spec against the last one. Each change is marked breaking or safe, with the migration path resolved.

02 / Fix

Your CI writes the fix

One workflow file in your repo polls Zenik on a schedule. On a breaking change, a coding agent runs on your own runner — your own LLM key — and edits only what the change touches.

03 / Review

You merge the pull request

A PR opens only when files change: what changed upstream, what was edited, what was left alone. Your tests run. An engineer merges.

Built for trust

We never see your code.

Zenik does not connect to your repository. The whole fix happens on your own infrastructure — we only tell your CI that something changed.

Runs on your runner

Code, file paths, and the diff never leave your CI. The runner is destroyed when the job ends.

Your own LLM key

The agent uses your OpenAI or Anthropic key, scoped to the job. Never sent to Zenik.

PR only

Every fix is a pull request. Nothing merges without an engineer's review.

Auditable by design

Zenik receives one run record: outcome, counts, token usage. It prints in your CI log.
