License the engine, not the memories.
No meter on remembering — no per-query, per-token, or per-retrieval pricing on any tier. You license the runtime once; recall stays a free function call inside your process.
Developer stays free. Pro and Enterprise are live — subscribe or manage anytime from your account.
The full engine for the person building — no feature gates, no card.
- Full engine — no feature gates on any memory operation
- MCP server for Claude, Cursor, and Codex (
telys mcp install) - On-device embedder; bring-your-own vectors always works
- Unlimited local data
- Personal, research, and evaluation use — plus dev & staging of commercial apps
- 1 user · 1 device · signed license · no card
Licensed to the people building and the machines running.
- Commercial production rights
- Licensed per developer seat and per production machine
- The same engine as every tier — no capability unlocks to buy
- Priority support
- Activates with
telys login --plan pro
The deployment license for server fleets — priced by the hardware, blind to the usage.
- Licensed by Compute Unit — 1 CU = 4 vCPU
- Production license for servers — pinned to one node, or floating across a pool via a relay you run
- Fully air-gapped activation
- RS256-signed license, verified locally
- No usage monitoring — it runs on your hardware
- A lapse degrades to the free tier — the runtime never stops
Design-partner-led. Ship Telys inside your own product.
- OEM & redistribution rights
- Air-gapped offline activation (telys runtime install --file)
- SSO / SCIM
- SBOM + signed-runtime attestation
- LTS releases and an SLA
The engine is identical on every tier.
Tiers change your rights — production use, fleet redistribution, support — not the engine. Memory operations are never gated, and never metered.
| Surface | What you get — on every tier, including free |
|---|---|
| memory ops | add · upsert · search · search_text · delete · compact · build_ivf · save · stats · snapshot — plus MVCC supersession. No tier gates any of them. |
| mcp server | telys mcp — a local stdio MCP server for Claude, Cursor, and Codex; one-command install and uninstall. |
| embedder | On-device and optional. add() takes your own vectors; only *_texts calls need an embedder. |
| data | Unlimited and local. Arrow in memory, Parquet segments on disk — your directory, your files. |
| meter | None. No per-query, per-token, or per-retrieval line item exists on any tier. |
One sign-in. Offline after.
telys login provisions an API key, registers the device, issues a platform-signed license, and installs the signed runtime — one command. License and runtime verify locally against Telys public keys; after that the engine runs fully offline, and nothing phones home at query time.
pipx install telys telys login # free device license + signed runtime — offline thereafter telys login --plan pro # commercial rights (subscribe on the pricing page above) telys runtime verify # re-verify signature + license locally — no network
How does billing work?
Developer is free forever. Pro is $25/month (or $250/year) with self-serve checkout; Enterprise is custom. Manage or cancel anytime from your account — memory operations are never metered, and the engine is identical across tiers.
How is the license enforced?
Sign in once — telys login installs a signed runtime and a signed device license. Both verify locally against Telys public keys, with no network. After that the engine runs fully offline: queries never touch the network, and there is no phone-home at query time.
What counts as a license?
A Pro license covers one developer building with Telys, or one production machine running it. Deployments scale by machine: each machine that runs the engine in production carries its own license — activated once with telys login, verified offline, never metered per query.
Can I use Telys for academic or open-source work?
Yes. The Developer tier covers personal, research, and evaluation use at no cost, and the SDK itself is Apache-2.0. Open-source maintainers whose project needs commercial-production terms: talk to us.
