Why developers love Toolhouse

  • Defining functions is annoying. You'll need to understand the prompt for the function, and build the payload. Toolhouse does that for you.

    Yoshimasa Niwa

    Software Engineer, X

  • I like the simplicity of the implementation! We can focus more on building and improving features rather than managing configuration and integration.

    Jacky C

    Software Developer

  • This makes so much sense! LLM providers diverge their implementation for no reason, and Toolhouse brings sanity to my codebase.

    CJ Avilla

    Software Engineer, Craftwork

  • I love the marketplace — it's like having npm, but is also shields the complexity away from developers. It helps any models that supports function calling be more powerful!

    Jamie Maguire

    Engineer, Microsoft MVP, AI

  • As a software development agency, I like Toolhouse because it allows me to build tools and functions for my client without giving them IP on my own tools.

    Fabio Pulvirenti

    CEO, Etiqa

  • I love that you give the utmost flexibility in terms of how the data is handled. Toolhouse works across LLMs and that's a fantastic reassurance in terms of privacy.

    Jim Bennett

    Head of Developer Advocacy, Pieces

  • Having tried building a few tools myself, I know how helpful those prebuilt components can be. LangChain doesn't do that. GPTs can't do that.
