DevCake: Open-Source Software Factory Runs Claude Code Pipelines From Linear Tickets
Antique_Juggernaut_7 · reddit · 2026-08-20
A Redditor released DevCake, a self-hosted, open-source "software factory" that automates the human side of operating Claude Code.
Instead of interacting with CLI agents session-by-session, you hand DevCake a Linear ticket and it runs a ONBOARD → PLAN → EXECUTE → REVIEW pipeline, where each step is a separate Claude Code/Codex run with templated prompts and curated context/skills — all configurable in an admin page, with no hidden prompts.
Key details:
- The onboarder splits overly complex missions into ordered sub-tasks pushed back to Linear
- The reviewer can reject executor output and trigger another EXECUTE pass; every step runs in a disposable container sandbox
- Each step starts fresh with no carried memory (an optional memory repo lets agents accumulate findings)
- Missions end in a PR; with multiple repos it picks the right one itself; all CLI output is logged to Linear
- Works with Claude Code, Codex and Grok Build, with experimental Pi, OpenCode and Qwen Code support; fully local via the bundled Gitea forge (author ran Grok Build paired with Qwen-3.6-27B on a 2xSparks box)
- Runs on a 16GB RAM Linux machine (11GB measured), single Docker command to start
The author has been using it to code DevCake's own repo by just operating a Linear board with a fleet of CLI harnesses.
