Devin Desktop (formerly Codeium) vs Replit Ghostwriter

Devin Desktop is an AI coding environment where you delegate tasks to agents that write code, run tests, and open pull requests while you review from a built-in IDE. The editor ships with syntax highlighting, autocomplete, and debugging tools, so you can jump into any agent-generated change without switching apps. It runs on macOS today with cloud agents (Devin Cloud) available on paid plans.

The product traces back to Codeium, a free autocomplete plugin for VS Code and 40+ editors, which grew into the Windsurf IDE before Cognition acquired it in 2025 and rebranded the app as Devin Desktop in 2026. That lineage matters because Devin Desktop still supports the Agent Client Protocol, letting you swap between Devin Local, Claude, Codex, and other agents in one surface rather than locking you into a single model vendor.

Individual developers who want agent-assisted coding without leaving their editor, engineering teams that need shared sessions and centralized billing, and enterprises evaluating SAML SSO with VPC deployment are the target users. The free tier covers light agent usage with unlimited Tab completions for anyone testing the workflow.

Replit Ghostwriter is Replit's AI coding line inside its browser IDE, and the public ghostwriter URL now highlights Replit Agent for building production-ready apps through chat. You describe an app or site, refine it in conversation, and Agent can search the web, connect Stripe or OpenAI, use built-in database and auth, and test its own work in a browser loop before you publish.

Compared with standalone autocomplete plugins, Replit bundles the editor, hosting, database, and agent workflows in one workspace. Agent adds Extended Thinking and High Power model options for harder tasks, plus automations that can talk to Slack or email. The trade-off is effort-based credits: heavy Agent builds consume monthly allowances faster than simple Ghostwriter completions.

Starter is free with daily Agent credits and one published project. Core costs $20 per month billed annually ($25 monthly) and includes $25 of monthly credits plus up to 5 collaborators and 2 parallel agents. Pro is $95 per month billed annually with $100 credits, 15 collaborators, 10 parallel agents, and 28-day database rollbacks. Students, indie builders, and small teams are the core audience.
