The repo-aware coding agent that plans, writes, and verifies whole features.
Zencoder is a coding agent built around a single idea: don't just generate code, prove it works. It maps your repository into a RepoGraph, plans changes across files, then runs your existing tests to confirm the result before opening a pull request.
Who it's for: Engineering teams and solo devs who want an autonomous agent that writes, runs tests, and opens verified PRs.
Zencoder indexes your entire codebase into a RepoGraph so the agent understands cross-file dependencies before it writes a line.
Describe a feature in plain English and Zencoder plans, edits, and runs tests across many files with minimal hand-holding.
The agent executes the project's own test suite and fixes failures before reporting back — fewer broken PRs.
Use it inside VS Code/JetBrains or as a CI bot that reviews and patches PRs automatically.
Zencoder is one of the few coding agents that actually closes the loop with your test suite instead of just generating plausible code. If you live in PRs and want an agent that verifies its own work, it is worth a serious look — the free tier is enough to judge.
