Lightweight session management for TypeScript
Lucia is a lightweight open-source auth library for TypeScript providing session management primitives without abstracting the database layer. Gives developers core building blocks — session creation, validation, invalidation — while they own the schema and auth logic. Supports any database through a simple adapter. Works with Next.js, SvelteKit, Astro, Express, and Hono. For developers wanting full control over auth implementation with minimal overhead and zero vendor lock-in.
Minimalist auth providing session primitives. Full control over database schema and auth flows.
Session creation, validation, invalidation, cookie management. Build custom login flows on top.
Database-agnostic through simple adapters. Works with any TS/JS framework.
Focused purely on sessions — for developers who want to understand every part of their auth.
100% free and open-source TypeScript authentication library and educational resource under the MIT/0BSD license ($0/mo). Provides lightweight session management patterns, zero-dependency cryptographic utilities (Oslo), database session storage recipes, and OAuth 2.0/OIDC guides without subscription fees, usage caps, or proprietary cloud lock-in.

Open-source background jobs and AI workflows for TypeScript
Trigger.dev is an open-source platform for building and deploying background jobs, AI agents, and long-running workflows in TypeScript. It eliminates serverless timeouts with durable task execution, automatic retries, queue-based concurrency control, and elastic scaling. Used by 30,000+ developers at companies like MagicSchool and Icon.com, it processes hundreds of millions of agent runs monthly. Backed by a $16M Series A led by Dalton Caldwell's Standard Capital fund.
Open-source PaaS alternative to Vercel, Heroku, and Netlify
Dokploy is a free open-source platform-as-a-service for self-hosting applications without cloud vendor lock-in. It provides automated deployments from Git repositories, built-in SSL certificates, database provisioning, Docker and Docker Compose support, and a clean web dashboard for managing multiple applications on your own servers. With 18,000+ GitHub stars, it fills the gap for teams wanting Vercel-like deployment simplicity on their own infrastructure.
