The honest brief
Athina AI
One platform spans the whole LLM lifecycle — prompts to production tracing — fed by an open-source eval SDK rather than a closed black box.
- 50+ preset + custom evals
- Human annotation tools
- Works with OpenAI, Bedrock, Vertex, Azure
- Datasets and experiments built in
- Monitoring platform is closed
- Broad scope can feel sprawling
- Smaller than LangSmith/Braintrust
- Free tier limited
Vellum
Passes model token costs straight through at cost, so the platform fee is unbundled from usage — unlike marked-up LLMOps tools.
- Visual builder plus Python SDK
- Prompt, RAG, eval, monitoring in one
- Eval and test suites before/after deploy
- Non-technical collaborators supported
- Free tier available
- Cloud-only platform
- Breadth over best-in-class depth
- Seat costs at Pro/Enterprise
- Lock-in to its workflow model
