Hands down, the best price in the market

We will never meter your agents: no credits, no runs, no tasks, no invented unit, so automating more of your data operation next quarter does not change your bill. We will never mark up your model spend - you bring your own key and your provider bills you directly, at your rate, at every tier and in the open-source core. Most of this market does - here is what we found when we read 52 pricing pages. We will never charge per seat, because the work is done by agents and the person who reviews it should not be a line item. And we will never lock you in: bring your own model, catalog, coding agent or context layer, keep the Apache-2.0 core, and leave with no notice period and no exit fee.

That is not how this market works. We read all fifty-two pricing pages before we wrote ours. Nineteen vendors have invented their own billing unit; ten take a margin on the model tokens you were going to buy anyway; one publishes the multiplier on its own pricing page. A data catalog listed on AWS Marketplace starts between $48,000 and $100,000 a year. We start at $12,000, and our bill does not grow when your agents do.

What can I use for free?

The open-source core, forever. Eleven specialist agents, each an MCP server, that you self-host, run against your own model key and modify however you like - no cap on anything, no expiry, no card. It is whole: no enterprise-only files hidden in the source tree, no licence-key check, nothing that stops working after a trial period. The managed platform is built on this core rather than beside it, so the tiers above add to what is there instead of unlocking it. It is also the fastest way to find out whether any of this works on your stack, and nothing leaves your network while you do. What it does not include is the managed platform itself - hosted orchestration, the connectors we maintain, browser context authoring, and a team that answers when something breaks.

Can I use my own data catalog?

Yes, and you should. The agents read and write through the catalog you already run - Atlan, Collibra, Unity Catalog, Polaris, OpenMetadata, whatever it is - rather than asking you to migrate into ours. The Spellbook Data Catalog is a control plane over your estate, not a replacement for it. Nothing on this page requires you to move a single asset.

Can we bring our own model or coding agent?

Yes, both, at every tier and in the open-source core. Anthropic, OpenAI, Bedrock, Vertex, Azure OpenAI or a local model - your key, your rate, your invoice. Claude Code, Codex, OpenCode, Cursor, or your own.

Who is in control when an agent wants to change something?

You are. An agent proposes, your approval workflow decides, and every change lands with a receipt you can audit. Agents are not permitted to quietly mutate your estate, on any tier.

What if we want to leave?

Leave whenever you like - there is no notice period and no exit fee. You keep the open-source core and everything you built on it: your context graph, your configuration, the eleven open-source agents, running on your own infrastructure. What stops is the managed platform - the proprietary agents, the hosted Conductor and the control plane. We would rather be chosen every year than be difficult to leave.
