Conifer

Conifer (YC S26) builds Sage, a local-first AI runtime and workspace that runs models entirely on your own machine. Its inference engine is written from scratch in Rust, reaching up to 60% faster decode than llama.cpp on Apple Silicon, and pairs an editor, integrated terminal, file viewers, and an agent runtime inside a kernel-level sandbox so tool calls only touch what you allow. Conifer routes each request to the cheapest capable model, starting with free on-device inference and falling back to cloud only when needed, cutting AI spend by up to 80%. The desktop app ships as Juniper for macOS, Windows, and Linux with no accounts, no telemetry, and no cloud dependency. Conifer is proprietary and distributed as compiled binaries; it currently exposes no public web API.

Conifer is profiled on the APIs.io network. Tagged areas include Company, Artificial Intelligence, Local AI, Inference, and Large Language Models.

Conifer’s developer surface includes changelog and 8 more developer resources.
