Baserun Alternatives
Baserun was acquired by LlamaIndex and is no longer available standalone.
If you are still running it, treat migration as scheduled work rather than a backlog item.
- 1
Teams that want one self-hosted MIT-licensed platform covering prompts, evaluation and observability, and who value environment promotion and branching over best-in-class depth in any single area.
From $0 self-hosted Self-hosts free - 2
Cross-functional product teams where non-engineers own prompt iteration and need to ship changes without a deploy, and who can work with enterprise procurement rather than self-serve pricing.
From Not published - 3
Teams that want self-hosted open-source prompt management with reusable components, and who care about closing the loop from production behaviour back to prompt changes.
From $0 self-hosted Self-hosts free - 4
Teams where non-engineers need to edit prompts safely, and where prompt governance - versioning, review, controlled release - is a real organisational requirement rather than a nice-to-have.
From $49/mo Bills requests - 5
Product teams that want a polished no-code prompt debugging and deployment surface, have a small and stable number of prompts, and value unlimited logging over low cost.
From $99/mo Bills prompts - 6
Small teams of two or three who want prompt management, evaluation and observability in one place with transparent pricing, and who will not grow the number of people needing access quickly.
From $150/mo Bills events - 7
Teams that want git-style prompt version control on a small budget, particularly where non-engineers need to work with prompts directly and runtime deployment is already handled elsewhere.
From $9/mo Bills requests - 8
Teams doing serious, reproducible model evaluation - safety testing, capability benchmarking, agent evaluation, or anything where the result has to withstand scrutiny. Also the right choice for anyone publishing evaluation results.

Frequently Asked Questions
Why do people look for Baserun alternatives?
Baserun was acquired by LlamaIndex and is no longer available standalone. That is the main reason this search exists, and it makes migration a requirement rather than a preference.
What is the closest free alternative to Baserun?
Agenta is the strongest option that self-hosts free - Teams that want one self-hosted MIT-licensed platform covering prompts, evaluation and observability, and who value environment promotion and branching over best-in-class depth in any single area. Free on licence is not free to operate though; you still own the infrastructure and the on-call.
How should I compare the costs?
Not by their published prices, because tools in this category meter different things - spans, events, GB ingested, seats, prompts, or a percentage of provider spend. A $50 plan means something completely different in each case. Model your own request volume and span count through the cost calculator instead.
