Free, self-hosted Protobuf schema registry

Hasir is a free, open-source Protobuf schema registry built for engineers. Manage, version, and distribute your Protocol Buffers without vendor lock-in. A lightweight, self-hosted alternative to Buf that integrates seamlessly into your existing workflows.
Self-hosting it on a small VM was painless, and the CLI feels close to what I'm already used to with Buf. The migration path from a hosted registry looks straightforward enough to actually try this quarter.
honestly this looks great, exactly what we needed. one thing that would be super helpful is a built-in linting or breaking change detection step before pushing a new schema version, basically catching things like removed fields or type changes that could break downstream services. would save us a lot of headaches during code reviews
Self-hosting is great but a one-click Fly.io or Railway template would save me a ton of setup time. Also would love to see a GitHub Action that auto-uploads schemas on merge so CI stays clean.
Spun it up locally and the self-hosted setup was honestly painless, took like five minutes. The schema versioning feels solid and the CLI is straightforward, basically exactly what I wanted from a buf alternative without the cloud dependency.
The self-hosted angle is such a refreshing call here, no telemetry, no surprise pricing tiers, just a clean registry you actually own. Love that it slots into existing workflows instead of forcing a whole new toolchain.
the fact that it's self-hosted and doesn't lock you into anything is honestly such a relief for teams already juggling CI pipelines. nice work shipping something this focused instead of bloating it with features nobody asked for.
