~15 MB idle RSS
Compiled Go daemon stripped to 7.2 MB. Boots in ~8 ms in CI — 32× faster than supervisord, 47× faster than PM2.
Lynx — secure systemd-native process manager for Linux
v0.9.8 · systemd-native · Linux
Run your apps like production infrastructure should.
Lynx is the secure, systemd-native process manager for Linux. A lean, hardened alternative to PM2 and Supervisor — ~15 MB idle daemon, ~8 ms cold start, zero-privilege deploy out of the box.

Six things PM2 and Supervisor don't give you.
systemd-native
Your apps outlive the CLI. systemd supervises directly — no custom watchdog to crash with them.
Zero-privilege deploy
DynamicUser + landlock isolation out of the box. Secrets never hit /proc/<pid>/environ or ps.
Namespace-native
Roll the whole tier with --namespace prod or 'prod:*'. No more xargs loops for bulk operations.
CLI OR Lynxfile
Declarative YAML for production, one-shot flags for dev. Export one into the other any time.
Signed releases
Prebuilt amd64 + arm64. Every release ships a signature, SLSA provenance, and SPDX SBOM.
Stack up against the old guard.
Numbers from CI bench — Ubuntu 24.04, kernel 6.17, idle daemon supervising 10 noop processes.

Ship the first process in under two minutes.
One .deb, one systemd unit, one CLI. Your services keep running when you log out — that's the whole pitch.
