Open source
Best open source AI & Machine Learning tools
Every app on this page publishes its source, and every listing names the SPDX licence and links the repository, because "open source" on its own is a marketing word and a licence is not. Agents, LLM tooling, copilots and model infrastructure, from prompt-to-app builders to the plumbing underneath them. Some of these are self-hostable and some are commercial products with an open core, so the pricing badge on each card still matters: open source and free are different claims and the listing keeps them separate.
