AuthFlow built an Algolia Custom Chat Agent to help developers wire its authentication PaaS. The startup, competing with Auth0 and Supabase, offers simple JWT-based email/password auth starting at $1.99/month. Developer analytics revealed users struggled with its RESTful API integration, prompting the chat assistant to provide real-time guidance.

The integration used GitHub CoPilot to accelerate development. The developer fed AuthFlow's documentation to CoPilot, which drafted prompt instructions and custom tools for the agent. After testing different LLM providers, they settled on gpt4o via OpenAI for its technical literacy on RESTful Bearer Authentication patterns across languages like JavaScript, Python, and cURL.

Algolia's Agent Studio proved critical for rapid prototyping. It allowed testing the chat feature with Provider LLMs before production wiring, separating LLM performance from integration bugs. This fast retrieval helped validate the UX pre-deployment, aligning with a KISS (Keep It Simple, Stupid) development philosophy and saving over a week of manual integration work.
