EmberLM

EmberLM is a developer workspace for prompt engineering. Compare outputs across Claude, GPT-5, and Gemini side by side. Define eval rules to know when a response is good enough. Run regression tests to catch quality drops before production. Debug MCP servers with a visual inspector. Track cost per model, per prompt. When you're ready, deploy prompts to production with a one-line SDK and update them without redeploying your app. Postman for the AI era.
