Free isn't a plan we maintain. It's an invariant our CI enforces. A public CI gate fails any commit that would put a local capability behind a paywall. Upgrading never changes what runs on your machine; the paid plane lives entirely server-side. See how the planes separate →

At a glance

Which plan is yours?

One question decides it: whose context are you managing? Yours on one machine (Free), yours on every machine (Pro), or your whole team's (Team).

FAQ

Plans and billing, answered.

Is the local tool really free?

Yes, forever. The entire local engine (reads, search, AST, shell compression, MCP tools, read modes, personas, plugins) is Apache-2.0 and runs without an account. Paid plans never gate a local feature; they only add team coordination, hosting, scale and governance.

What is Pro, and how is it different from Supporter?

Pro ($9/month or $90/year) is your Personal Cloud: a hosted, account-bound service that syncs and backs up your own learned context (knowledge & memory, shell patterns, CEP scores, gotchas and more) across every device you work on. It also includes the Hosted Personal Index (1 GB): push your project’s retrieval index once and a fresh machine gets working semantic search in seconds, with bundles encrypted end-to-end so the server only ever stores ciphertext. Supporter is a voluntary tip that funds development and grants recognition only (a badge), never a capability. Pro is for an individual who wants their own context everywhere; Team is for sharing one audited context across people.

What exactly does Team add?

A shared, audited context plane: one workspace your whole team and your CI agents query, with role-based access (viewer / member / admin / owner), a full audit log of every access and a live shared event stream, plus a hosted retrieval index with a usage dashboard, managed GitHub/GitLab connectors and a private extension & persona registry. It is purely additive: your local setup keeps working exactly as before. Marketplace revenue share is on the roadmap and labelled as such on the plan.

Is the hosted team server available right now?

Yes. The team server is production-ready and you can self-host it for free (Apache-2.0). Prefer managed hosting? The moment your Team checkout completes we provision your private team server for you. From then on you manage everything (server URL, owner token, member seats with role-based access) yourself from your account dashboard under Account → Team.

How is Team billed?

Per seat: $18/seat/month (or $180/seat/year, ~17% off). You pick how many seats you need (1–25) at checkout; afterwards add or remove seats anytime (straight from your team dashboard or the billing portal) and Stripe automatically prorates the difference. Adding a member when every seat is taken simply buys one more seat. Switch cadence or cancel any time; cancellations take effect at the end of the period.

What happens if our hosted index goes over 5 GB?

Nothing breaks. The hosted retrieval index includes 5 GB; beyond that, storage is metered at $0.25/GB per month and billed through Stripe alongside your seats. Your account dashboard shows live usage against the quota, and we email the team owner at 50%, 80% and 100%, so there are never surprise bills. Prefer no metered storage at all? Self-host the team server (Apache-2.0) and you own the disk.

We need org SSO or longer audit retention — what now?

That lives on the enterprise plane: org-wide SSO, fleet policies, longer audit retention and signed compliance exports on top of the same open-source core. See the Enterprise page or write to enterprise@leanctx.com — and if you are already on Team, any upgrade switches your subscription in place, prorated, so you never pay twice.

Can we self-host instead?

Yes. The audited team server is Apache-2.0 and self-hosting is a free capability; see the “Self-host a team server” journey. Need SSO, unlimited scale or a support SLA? Talk to us at hello@leanctx.com.

Ready?

Free to start. Yours to scale.
