Fine vs Replit Ghostwriter

Fine helps teams ship web apps and automate development work through AI agents that handle UI, backend, database, auth, and deployment from a single prompt. Describe what users should do in your app and Fine generates a full-stack project with Google, GitHub, or email login, a ready Postgres database, serverless backend functions, and one-click deploy to a custom domain.

Unlike pair-programming assistants that suggest the next line, Fine runs asynchronous agents across entire repositories. They open issues, write pull requests, compile code, run tests, and iterate until the task finishes without you watching every keystroke. The team plan at $13 per seat monthly (billed yearly) adds unlimited chat sessions, indexed repos, custom AI workflows, and an AI sandbox with premium LLM access.

Startup teams, indie builders, and engineering leads use Fine for SaaS prototypes, internal dashboards, AI agent apps, and backlog automation. A free tier covers 25 messages per month with unlimited projects, while Builder at $19 monthly unlocks custom-domain deploys and always-on databases for production apps.

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.
