Why these together

This is the stack a 5-20 person engineering team self-hosts when GitHub Enterprise is overkill but a public GitHub repo is wrong. Gitea hosts the git + issues + wiki; Drone wires CI (Woodpecker is the closer-to-OSS-governance fork — pick that instead if governance matters more than feature pace); Harbor stores built images with vulnerability scanning baked in; GlitchTip catches errors and is wire-compatible with Sentry SDKs so existing instrumentation keeps working unchanged; Coder gives reviewers ephemeral cloud dev environments. The compose.yml on this page ships Gitea (sqlite) + GlitchTip (web + worker + postgres + redis) — the two pieces that compose cleanly without an out-of-band bootstrap. Drone needs a Gitea OAuth app + shared RPC secret; Harbor ships its own preparer; Coder needs postgres + access-url config — all three are linked from inside the file. Once running, GlitchTip project tokens drop into your runtime, and the full stack on a $40 VPS for a team of 10 stays the realistic target.
