# Plans & licensing

Telys ships as one package on every plan. Your tier is a signed license that the runtime reads offline; it raises limits, not a different build. For current prices and checkout, see [**telys.ai/pricing**](https://telys.ai/pricing) — the single, always-current source (this page does not repeat prices, so they can never drift).

## The four tiers

| Tier               | Best for                                                       | Devices                                                           |
| ------------------ | -------------------------------------------------------------- | ----------------------------------------------------------------- |
| `telys_developer`  | Local, on-device experiments and single-machine use — **free** | 1 device                                                          |
| `telys_pro`        | Commercial and multi-machine on-device use                     | Multiple (see [Seats & devices](/licensing/seats-and-devices.md)) |
| `telys_team`       | Self-hosting a shared server (`telys serve` + `RemoteTelys`)   | Per seat                                                          |
| `telys_enterprise` | Procurement, security review, and volume                       | Negotiated                                                        |

{% hint style="info" %}
Every tier runs the same on-device engine. A higher tier lifts limits (devices, commercial use, serving); it does not change where your vectors live. See [What leaves the machine](/security/what-leaves-the-machine.md).
{% endhint %}

## What each tier unlocks

{% tabs %}
{% tab title="Developer (free)" icon="user" %}
`telys_developer` is the default plan: free, self-serve, one device. Sign in and you are done:

```bash
pipx install telys        # or: pip install telys
telys login               # defaults to --plan telys_developer
```

Use it for prototypes, local agents, personal RAG, and evaluation. It runs the full engine, all embedders, tuning, and the MCP server — the only limit is the single device.
{% endtab %}

{% tab title="Pro (commercial)" icon="rocket" %}
`telys_pro` is the commercial plan, billed via Stripe checkout — see [telys.ai/pricing](https://telys.ai/pricing) for the current price. It authorizes commercial use and multiple devices under your account.

```bash
telys login --plan telys_pro
```

The command starts the device-code flow. Without an active subscription, it routes you to Stripe checkout in the browser; once active, your license is issued and cached locally. To add devices or change billing, see [Manage your subscription](/licensing/managing-subscription.md).
{% endtab %}

{% tab title="Team (self-host)" icon="server" %}
`telys_team` is the self-hosting plan: run a shared instance with `telys serve` and connect with `RemoteTelys`. Use it when several people or services share one collection store over a socket or TCP.

```bash
telys serve --path ./memory --host 0.0.0.0 --port 8099 \
  --access-token "$TELYS_ACCESS_TOKEN" \
  --license "$TELYS_LICENSE" --require-license
```

With `--require-license`, the server verifies a `products.telys` (version 2) license offline on boot and refuses to start without one. See [Serving overview](/self-hosting/overview.md).
{% endtab %}

{% tab title="Enterprise (sales)" icon="building" %}
`telys_enterprise` is sales-led — for procurement, security review, negotiated device and seat counts, and volume terms. Contact us through [**telys.ai/pricing**](https://telys.ai/pricing) or [Support & contact](/resources/support.md).
{% endtab %}
{% endtabs %}

## How the tier is enforced

Your tier travels as a signed, offline JWT — not a server call. At sign-in, Telys fetches a license recording your `tier` and `features` and caches it locally. The runtime verifies it with an embedded public key and never phones home:

* The license is a `products.telys`, version-2 JWT signed by `https://license.algenta.ai`.
* It is verified locally by `telys.verify` and `telys runtime verify` — see [Offline licenses & verification](/licensing/offline-licenses.md).
* It carries an expiry plus a grace window, so a lapsed network connection does not lock you out mid-session.

{% hint style="warning" %}
Because enforcement is a signed license, a billing change is not instant on a device — it picks up the new tier on the next license refresh (for example, the next `telys login`). See [Manage your subscription](/licensing/managing-subscription.md).
{% endhint %}

## Choosing a tier

* Building on your own laptop, evaluating, or shipping a personal project → **`telys_developer`**.
* Using Telys commercially or across more than one machine → **`telys_pro`**.
* Running one shared server that many clients connect to → **`telys_team`**.
* Need procurement, a security review, or negotiated volume → **`telys_enterprise`**.

## Where to sign up

* **Pricing and plan comparison:** [telys.ai/pricing](https://telys.ai/pricing)
* **Accounts & billing portal:** [accounts.thyn.ai](https://accounts.thyn.ai) — the same identity you use for `telys login`
* **Start free right now:** `telys login`

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.telys.ai/licensing/tiers-and-pricing.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
