First Impressions
I hated setting up dev environments. Replit fixed that. I opened a URL, selected 'Node.js', and I had a server running in 30 seconds. The multiplayer feature felt like Google Docs for code.
Best Feature: Ghostwriter
Their AI, Ghostwriter, is integrated directly into the environment. It can debug the running terminal, which is huge. I got an error, clicked 'Debug with AI', and it fixed the config file automatically.
The Verdict
For prototyping, hackathons, and learning, Replit is unbeatable. I wouldn't build a massive enterprise app on it yet, but for everything else, it's a joy.
