The World's Largest Developer Community
Hackathons, fellowships, and DEV's online community. 5 million software creators learn, build, and share together.
Connecting the Tech Ecosystem
Discover the real world developer tools you'll need throughout your career.
MLH is where you build. We’ve created a home for software creators at every stage. Build something at a hackathon. Write about what you learned. That knowledge becomes permanent, searchable, and useful to the next person. Companies like Google, GitHub, ElevenLabs, and Snowflake support our community because this is where developers discover and get hands-on experience with the tools shaping the future of software.
