What is Simba?
Simba is an open-source customer service assistant built for teams who need full control over their AI. Unlike black-box solutions, Simba is designed from the ground up around evaluation and customization, so you can measure performance, iterate fast, and tailor the assistant to your exact needs.
Why Simba?
Simba tackles one of the most persistent challenges in AI: measuring quality. Unlike many AI tools that offer no built-in way to assess performance, Simba includes a comprehensive evaluation framework that tracks both retrieval and generation accuracy. This means developers can objectively measure how well their AI responds — not just by gut feeling, but through concrete metrics like precision, recall, F1 scores, and semantic similarity. With this, teams can iterate faster, debug issues, and ensure consistent results across different use cases.
Another major pain point? Generic or irrelevant responses. Simba solves this with a fully customizable RAG (Retrieval-Augmented Generation) pipeline that’s powered by your own data.
Integration is often a bottleneck, especially for non-technical teams. Simba removes that friction with a simple, drop-in npm package that enables instant deployment on websites. No complex setup. No backend servers to manage.
Finally, Simba stands out by rejecting vendor lock-in. It’s open-source, self-hosted, and modular, meaning you can swap out any component at any time. Want to switch from one LLM to another?
Use a different vector database? Replace the embedding model? All possible. This flexibility empowers teams to maintain control over their AI stack, avoid dependency traps, and future-proof their applications, all while keeping privacy and security at the core.
