About

EidoStack is a browser-based workspace for AI engineers to interact with, evaluate, compare, and select the right AI models before production. Use AI models for everyday conversations and development tasks, test the same prompts across different models, compare responses side by side, and analyze token usage, estimated costs, performance, and context behavior. EidoStack provides configurable system prompts, context strategies, chat history, model comparison, and usage analytics, helping developers work with multiple AI models and make informed decisions about which model best fits their application.

About

Promptfoo discovers and eliminates major LLM risks before they are shipped to production. Its founders have experience launching and scaling AI to over 100 million users using automated red-teaming and testing to overcome security, legal, and compliance issues. Promptfoo's open source, developer-first approach has made it the most widely adopted tool in this space, with over 20,000 users. Custom probes for your application that identify failures you actually care about, not just generic jailbreaks and prompt injections.

Used by teams serving millions of users and supported by an active open source community. Build reliable prompts, models, and RAGs with benchmarks specific to your use case. Secure your apps with automated red teaming and pentesting. Speed up evaluations with caching, concurrency, and live reloading.
