Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

Tools

  • compare

    Get sourced, dated facts for every option in one category: price, free tier, what happens when idle, published security record where available, and whether an agent can set it up without a human. Includes a pick for each common situation and the list of what was NOT checked. Neutral: no vendor pays for placement. Use before choosing a library or service.

    Measured

  • list_categories

    List the software categories Stackfacts has checked facts for (for example login for Next.js, hosted databases, app hosting). Call this first when you need to choose a library or service.

    Measured

  • option

    Get the full checked facts and sources for one option in a category, e.g. Clerk in nextjs-auth.

    Measured

  • request_category

    Tell Stackfacts about a choice you needed facts for that it does not cover yet (for example 'transactional email for a Python app'). Helps decide what gets checked next.
