An open-source platform for building, testing and deploying prompts as production endpoints.
Pricing
Verified 15 Jul 2026Overview
Latitude is a prompt-engineering platform aimed at developers and teams who treat prompts as real software rather than throwaway text. You author prompts in a collaborative editor, version them, run evaluations against test cases, and publish them as API endpoints your application calls — with logging and observability so you can see how they behave in production. It is open source, which means you can self-host and inspect it rather than being locked into a black box. For engineering teams shipping LLM features, that combination of versioning, evaluation and deployment is the point: it brings prompts under the same discipline as the rest of the codebase. The trade-offs are about audience and maturity. This is not a tool for non-technical prompt browsers — it assumes you're comfortable with APIs, test cases and evaluation metrics. As a younger product the surface is still evolving, and self-hosting means owning the infrastructure. If you want a serious prompt-ops workflow and prefer open source, it's a strong fit; casual users will find it far heavier than they need.
