Agenta vs Latitude
Both are prompt management tools. Here is how they actually differ on price, billing model and deployment.
Agenta
An MIT-licensed LLMOps platform bundling prompt management, evaluation, human annotation and observability, with a visual playground for side-by-side comparison. Actively shipping, self-hostable, and broader than most open-source competitors.
Latitude
An open-source prompt engineering platform built around the production feedback loop. Widely reported as LGPL-3.0 by a competitor - the repository says MIT, which is a materially different commercial proposition.

Our verdict on Agenta
Agenta is the broadest MIT-licensed option in this segment and a sensible default if you want one self-hosted tool rather than three. It covers prompt management, automated evaluation, human annotation and observability, with an interactive playground for side-by-side comparison and support for 50+ providers including self-hosted models. The versioning model is better than most - branching and environment promotion means you can develop a prompt on a branch and promote it through environments rather than just rolling back a linear history, which is closer to how you already ship software. It is actively maintained, with v0.82.0 shipping in February 2026 and roughly 4,200 stars. The trade-off is depth. The evaluation surface is lighter than DeepEval or Ragas and the observability lighter than Langfuse, so a team with a serious requirement in either area will end up pairing it with something. One note on reading their material - Agenta publishes competitor comparisons, and we found their licensing claim about Latitude to be wrong in a way that disadvantages a rival.
Full Agenta review →Our verdict on Latitude
Latitude is a good open-source prompt platform carrying a licensing rumour that deserves correcting. Comparison content in circulation states it is LGPL-3.0 and warns that modifications must be published under the same terms, which would be a genuine blocker for many commercial teams. The repository states MIT. We checked because the LGPL claim originates from a direct competitor's blog, and MIT versus LGPL-3.0 is not a nuance - it is the difference between a tool your legal team waves through and one they reject outright. On the product, the standout feature is dynamic and reusable prompt components, which means a shared instruction block lives in one place rather than being copy-pasted across twenty prompts and drifting. That is a real problem at scale and most competitors do not solve it. Project health looks solid at roughly 4,500 stars and 5,500-plus commits with active issues and pull requests. Verify the license yourself before committing, as you should with any tool where the answer decides the purchase.

What is the main difference between Agenta and Latitude?
Agenta: 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. Latitude: 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. Both sit in Prompt Management, so the decision usually comes down to billing model and deployment rather than raw capability.
Which is cheaper, Agenta or Latitude?
It depends entirely on your workload shape, because they meter differently - Agenta bills on no usage metering and Latitude bills on no usage metering. Published starting prices are $0 self-hosted and $0 self-hosted respectively, but those numbers are not comparable until you apply them to the same traffic. Use our cost calculator to model both against your own request volume and span count.
Can I self-host Agenta or Latitude?
Agenta: Yes, free. Latitude: Yes, free. Free self-hosting means no licence fee, not no cost - you still own the infrastructure, upgrades and on-call.
