What it does
Evaligo lets you build a flow of prompts, agents and tools on a drag-and-drop canvas, or describe a flow in one sentence and have it built. A flow can run as several variants where only the model, prompt or reasoning setting changes, including OpenAI, Google and Anthropic models and open-source models through one OpenRouter key. Variants run over a dataset of your own inputs, or a test set that Evaligo generates from a short description. AI judges score every output blind against a rubric you write, using one judge model or a panel of three from different vendors. Results appear in a scoreboard of score, cost and speed per output, and a finished experiment can train a router that picks a model per input. A winning variant can be promoted with one click, and any flow can be deployed as a REST API with authentication, documentation, code examples, batch processing and monitoring. Credits pay for model calls made with platform keys, while your own API keys give unlimited usage on any plan.
Capabilities
- Drag-and-drop flow editor
