Pricing
Calame is dual-licensed: the core is Apache 2.0, free forever. The Enterprise modules (SSO + RAG) are BUSL 1.1 — free for your own use, paid only when you embed them into a product you sell.
Self-host Calame freely. Apache 2.0, no limits.
Forever — Apache 2.0
All features, single instance. Perfect for one team or one product.
Per instance · billed monthly
Unlimited instances, priority support, embedding rights.
Annual license — quote based on usage
Calame, hosted. We run the servers, you run the profiles.

All tiers — your data stays on your infra. Calame never phones home.
License model
Calame separates its core from its enterprise modules at the directory level. The split is mechanical — you can read the license boundary in the source tree.
Connectors, profiles, MCP runtime, masking, chat, audit, the entire web UI. Use it freely, fork it, modify it, deploy it in production. Patches welcome.
OIDC SSO and RAG ingestion. Free for internal use, evaluation, and contributions. A commercial license is required only if you embed these modules in a paid product offered to third parties.
Internal corporate use, self-hosting Calame, contributing patches, forks that aren't paid commercial offerings. Almost everything you'd want to do.
Reselling Calame as a managed service, or embedding ee/sso, ee/rag-core, ee/rag-connectors in a paid SaaS that competes with Calame Cloud.
So that solo maintainers can keep building the project full-time without seeing it forked into a closed paid product they can't sustain. Every BUSL version converts to Apache 2.0 after 4 years anyway.
Compare
Everything in Community is in Enterprise and Cloud. Enterprise adds the BUSL-licensed modules. Cloud runs the same code, hosted.

FAQ
If your question isn't here, the contact form lands directly in our inbox — we usually reply within a business day.
It depends. If you only need the Apache-2.0 core (connectors, profiles, PII, chat, audit, OAuth), Community is enough — forever, free, unlimited instances. As soon as you want SSO or RAG (the ee/ modules), you need Pro (one instance) or Enterprise (multiple instances).
One Calame process — i.e. one running container or one Node server. Staging, preview, dev environments owned by the same team count as the same instance for license purposes; we apply common-sense, not a license-server.
Three cases. (1) You run Calame on more than one production instance — different products, different regions, different teams. (2) You want a 1-business-day support SLA. (3) You want to embed the ee/ modules into a paid product you sell to third parties (a "Competing Offering" under BUSL). Anything else fits Pro.
Each BUSL-licensed version of Calame ee/ automatically converts to Apache 2.0 four years after publication. So today's Pro/Enterprise features become free OSS in four years, automatically — your license fee buys you the rights to use the most recent code right now.
Annual license, scoped to your deployment. Pricing depends on number of instances, team size, and whether you embed ee/ modules in a product you sell. Reach out via the contact form and we send a quote within a business day.
Yes — we offer a 30-day evaluation license that unlocks SSO and RAG. Mention "evaluation" in the contact form.
No. Cloud runs the same Calame binary as the self-hosted distribution. You can export your config and migrate to self-host any time.
From git clone to first MCP query
One Docker command. One profile. One MCP URL. Your database stays where it is — Calame just decides what your LLM is allowed to see.
