Who should pick which

  • Solo founder building an MVP
    Pick: Freebuff

    Freebuff's prompt-to-deployed-app web builder and free CLI agent let you build and ship a prototype at zero cost, using frontier models like DeepSeek V4 Flash with daily limits sufficient for early-stage development.

  • Enterprise engineering team maintaining large production codebase
    Pick: Cognition AI

    Devin's autonomous planning, coding, and PR creation, plus integrations with GitHub, Jira, and Datadog, reduce manual effort. The $10M productivity guarantee and Auto-Triage for bug monitoring provide enterprise-grade reliability.

  • Student learning to code
    Pick: Freebuff

    Freebuff is free, requires no credit card, and offers multiple models. It's a risk-free way to experiment with AI-assisted coding, ideal for educational purposes without budget constraints.

  • IT team modernizing COBOL legacy systems
    Pick: Cognition AI

    Cognition AI specifically supports COBOL modernization, a niche that Freebuff does not address. Devin can autonomously handle legacy code conversion, making it the only viable choice here.

  • Freelance developer needing zero-cost tool for side projects
    Pick: Freebuff

    No cost, no API keys, and daily limits that suffice for non-continuous work. Freebuff's CLI and web builder provide flexibility without subscription lock-in.
