Open-source browser infrastructure for AI agents at scale
Steel is an open-source browser API purpose-built for AI agents, providing managed headless browser sessions with anti-bot bypass, proxy rotation, CAPTCHA solving, and session persistence. It handles the infrastructure layer that browser automation agents like Browser Use and Stagehand run on top of. Self-hostable or available as a cloud service. Over 6,000 GitHub stars.
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.
Clerk and Better Auth represent the managed versus self-hosted divide in modern authentication. Clerk is a hosted platform with pre-built UI components, session management, and user dashboards that gets teams to production fast with minimal code. Better Auth is an open-source TypeScript library offering the same breadth of features including passkeys, two-factor auth, and RBAC but running entirely on your own infrastructure with zero vendor dependency.
