The public tier is free. Forever.
Bitcoin has no foundation, and neither does Flow. The people and organizations who need the most of it fund it for everyone else. Pay for scale and depth, and for the tools a working team needs — never for influence over a label.
No ads. No data sales. No trackers. Supporter is free while the beta lasts.

Built for work that has to hold up.
Due diligence, compliance reviews, litigation support, expert work, research. The tier for people whose output goes in front of a client, a partner or a court.
Every label with its source. The document, the quote and the date behind each name, so a reader can check it without trusting us.
The whole cluster. How many addresses Flow says belong together, and every one of them in a list.
Your traces as data. Export a graph as JSON and take it into your own tooling.
Billing the way firms buy. Monthly or yearly, on invoice.
Received. Expect a reply within a few days with the next steps.
Every capability, by tier.
What each account can do, as the product enforces it today. A check means it is live; “soon” is on its way.

1 Publishing a share link, voting and tagging need a verified email address, not just an account.
One unit per cluster, per month.
Opening a cluster, or adding it to the graph, is one unit. Every tab of it is included — counterparties, transfers, exposure, ordinals — and opening it again that month costs nothing.
Search is free.
Suggestions as you type and the search itself cost nothing. A unit is charged when you open or add a result.
Published traces are free to view.
Anyone can open a shared trace without an account. The units belong to whoever built it.
Money never buys attribution influence.
No tier buys label weight or curator status: influence is earned by track record alone, and a Professional or Enterprise account votes with exactly the weight its history has earned. Labels on Flow are hypotheses with their sources and confidence shown, never verdicts. Read the doctrine →
Want to deploy Flow within your organization?
Enterprise allows white-labeling and customer instances: Flow under your name, running for your organization — on our infrastructure or on your own servers, including semi air-gapped configurations for sensitive workspaces. Add more access to data, metered API access, a pooled allowance sized to the team and onboarding with us. Tell us what your team needs and we scope it together.
We ask only for what a reply requires: a contact address and your message. No account, no tracking pixels, no analytics on this form, and no third-party data sharing. Pseudonymous inquiries are fine.
Received. Expect a reply within a few days.
The ones we always get.
Will the free tier stay free?
Yes. Forever. Free public access is the founding commitment of this project, and the paid tiers exist precisely so it never has to change. Organizations fund the platform; the public uses it. If the economics ever forced a choice, the paywall loses — not the public.
What counts as a cluster?
One unit is one distinct cluster a month. Open it, add it to the graph, switch every tab, come back next week — still one unit. Search and suggestions are not metered. Counters reset on the first of the month, and the usage meter in your account shows where you stand.
Why is Supporter free right now?
Flow is in beta. Every new account gets Supporter — full counterparty lists, indirect exposure, Nearest, Roles and 150 clusters a month — at no charge while we finish it. A price comes later, with notice, and nothing you saved goes away.
What does Professional include, and how do I get it?
Everything in Supporter, plus the size of every cluster and its Addresses tab, the source citations behind every label, export of your traces as JSON, 1,000 clusters a month, invoice billing and priority support. It is set up by inquiry: tell us about your organization and we reply with the next steps.
What happens when I use up my clusters?
The meter fills, the app tells you when it resets, and everything you already opened this month stays open. Enterprise allowances are pooled and set in the contract.
What does Enterprise include?
Enterprise is custom. White-labeling and customer instances, on-premise deployment on your own servers (including semi air-gapped configurations for sensitive workspaces), more access to data, a metered API for clusters and flows, a pooled allowance sized to the team and onboarding with us. Tell us what you need above and we scope it together.
Who pays for Flow?
No foundation. Bitcoin has none, and neither do we. Full-chain clustering runs on hardware and bandwidth somebody has to fund, so the organizations that need the most of Flow fund it for everyone else: Enterprise and Professional today, Supporter subscriptions once the beta ends.
Does paying affect labels?
Never. This is doctrine, not policy: money never buys attribution influence. No paid tier grants label weight or curator status. Attribution influence is earned one way — by being right, repeatedly, in the open.
