We build open source developer infrastructure — fast, minimal, and production-ready.

JointOps is an open source organization building tools that Node.js and Bun developers actually want to use. We obsess over performance, zero-dependency design, and developer experience.

The fastest rate limiter for Node.js & Bun. A modern alternative to express-rate-limit.

• 7M+ ops/sec on Bun, 5.96M+ ops/sec on Node.js
• 8 built-in storage backends (Memory, Redis, SQLite, Postgres, MongoDB, MySQL, Valkey, DragonflyDB)
• Supports Express, Fastify, Hono, NestJS, Bun.serve, Elysia — one API across all frameworks
• Built-in tiered limits for SaaS (Free / Pro / Enterprise in one config)
• ~8KB core, zero dependencies

npm i @joint-ops/hitlimit       # Node.js
bun add @joint-ops/hitlimit-bun  # Bun

Drop-in Express API compatibility for Bun. Same req, res, next — native Bun performance.

• Full Express.js API surface (routing, middleware, req/res/next)
• Built for Bun from the ground up
• Migrate Express apps to Bun without rewriting your routes

bun add bunway

--- kaput — Graceful Shutdown for Node.js

Zero-config graceful shutdown handling. Stop losing in-flight requests on deploy.

• Handles SIGTERM, SIGINT, and uncaught exceptions
• Works with Express, Fastify, and raw Node.js HTTP servers
• Zero configuration required

npm i @joint-ops/kaput

• Performance is a feature. We benchmark everything and publish the numbers openly.
• Zero dependencies by default. Your bundle shouldn't pay for our convenience.
• Framework-agnostic. Tools that work across your whole stack, not just one framework.
• Production-first. We build things we'd run in prod ourselves.

All our projects are open source under the MIT license. We welcome contributions of all kinds — bug reports, feature requests, documentation improvements, and pull requests.

Every repo has a CONTRIBUTING.md with setup instructions. The easiest way to start:

1. Browse open issues across all our repos
2. Join the conversation — hitlimit discussions · bunway discussions
3. Pick something and send a PR — we review fast
