Replit

Replit is a web-based development platform for solo developers, students, freelancers, and teams to build and deploy apps and sites collaboratively with AI assistance, without local setup.

Key capabilities include:

• Replit AI (Agent and chat) for code generation, completion, debugging, and iterative help while building.
• Multi-language workspaces for common stacks, including Python, JavaScript/TypeScript, Java, C++, and Go.
• Real-time collaboration with multiplayer editing, plus collaborator and viewer limits on paid plans.
• Deployments and infrastructure for publishing web apps and APIs, with integrated databases (Replit Database and PostgreSQL) and configurable cloud compute (vCPUs, RAM, storage).

Pricing: Freemium. Starter is Free. Replit Core is $20/month billed annually (or $25/month) with monthly credits. Replit Pro is $95/month billed annually (or $100/month) with higher credits. Enterprise offers custom pricing. Plans include usage credits for AI, compute, and deployments, with pay-as-you-go overages.

Notable for combining an in-browser IDE, AI agent workflows, multiplayer collaboration, and built-in deployment plus databases in one place, with integrations such as Stripe, Twilio, OpenAI, Claude (Anthropic), and Firebase Auth.
