Replit’s Agent 3 feels like a friendly teammate that quietly gets work done for you. Give it simple instructions and it can run on its own for long stretches, test and fix its own code, and show progress in real time so theoretically you spend less time babysitting projects.
What makes this one stand out is the mix of long, uninterrupted runs and built in self testing plus the ability to spawn small automations you can hook into tools like Slack or email. Many recent updates from other platforms focus on agent building blocks or browser integrations, but according to its promo, Agent 3 packages long autonomy, ongoing self improvement, and easy automations in a simple, approachable way. But I’ve seen mixed reviews. Some saying it takes way longer and fails too often, and some saying it’s the most marvelous thing ever. I’ll be testing it soon.
