Validate agent-generated code before it ever reaches CI
AI agents write code fast. Validation still happens after the push — by then the context is gone. Chunk sidecars run scoped microbuilds before commit, in a real CI mirror. Auto-detects your stack. ~27s average vs ~5 min billable compute for a full run. 3x–5x fewer tokens in retry loops. If something fails, the agent iterates before anything reaches shared CI. Run chunk init. Works with Claude Code, Codex, Cursor, or custom agents. Free for all CircleCI users.
Hey Product Hunt 👋
One thing that became obvious while experimenting with agent workflows internally: the code generation is becoming the easy part. The expensive part is when validation happens after the push, CI fails, and now the agent has already moved on and lost the useful context around the change.
We’re also seeing this show up in the broader data. In our 2026 State of Software Delivery report, build volume increased 59% year over year while main branch success rates dropped to a 5-year low.
That’s why we built Chunk sidecars. They run lightweight microbuilds against environments that mirror your CI stack while the agent is still iterating on the code. Feedback comes back in under 60 seconds, so failures get caught before they ever hit shared CI.
Here’s a short demo: https://circle.ci/4dq9fph
Would love feedback from people already experimenting with AI-assisted development workflows!

Who hunted Chunk sidecars?
Chunk sidecars was hunted by Olaf Molenveld. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
