Terms & License
Last updated September 2026
These terms cover using Libraries.dev — the free, open-source effect libraries (Beam, Orb, Gooey, Metal and Image), the Libraries Pro subscription with the Studio and Pro content, and Team plans. By using the site or subscribing you agree to them. In short: use the libraries in as many projects as you like, including commercial ones; a subscription bills until you cancel; and what you've already downloaded stays yours.
Using the libraries
The five libraries — Beam, Orb, Gooey, Metal and Image — are open-source npm packages released under the MIT License. Install them, modify them, and ship them in unlimited personal and commercial projects.
Pro content — the Studio's Pro presets, recipes, and everything unlocked by a Libraries Pro plan — may likewise be used in unlimited personal and commercial projects once you have access. The one thing you may not do is redistribute the Pro content itself — you can't repackage, resell, or publish the Pro presets and recipes (or a substantial part of them) as a competing library, template pack, or component kit. Use them in your products, not as a product of their own.
Libraries Pro
Libraries Pro is a paid subscription that unlocks the Studio — deep, per-library customization of all five libraries — plus the Pro content: presets, recipes and guides, delivered on the site and through downloads, with every update released while your plan is active.
- Billing & renewal. Pro is billed monthly or yearly through Stripe and renews automatically at the end of each period until you cancel. Prices are shown at checkout.
- Lifetime plans. Solo and Team lifetime plans are a one-time payment — no renewal, nothing to cancel. They include ongoing access and every future update for as long as the service operates. Team lifetime includes a fixed 5 seats.
- Updates. While your plan is active you receive new libraries, Studio improvements, and new Pro content at no extra charge.
- You keep what you've downloaded. Cancelling stops future access, downloads, and updates — but any files already added to your projects continue to work and remain licensed under the terms above.
Cancellation & refunds
You can cancel any time from your account. Your plan stays active until the end of the period you've already paid for; we don't prorate partial periods. If something's wrong — a double charge, a technical problem that stops you using Pro — email jakubja@gmail.com and we'll make it right, including a refund where fair. EU/EEA consumers may have a statutory right of withdrawal; by starting to download Pro content immediately you acknowledge digital delivery begins at once.
Team plans
A Team plan buys a set number of seats, billed per seat. The team owner invites members up to the seat count (a pending invitation reserves a seat), manages roles, and can add or remove seats, which adjusts billing accordingly.
- Each member gets full Pro access while they belong to an active team.
- Removing a member, or the team's subscription ending, ends that person's Pro access — again, already-downloaded files keep working.
- The owner is responsible for who they invite and for the team's billing.
Your account
Accounts use passwordless email sign-in. Keep access to your email secure — anyone who can receive your sign-in link can access your account. Don't share credentials, probe or abuse the service, attempt to bypass the entitlement checks, or scrape the Pro content. We may suspend accounts that do. How we handle your data is described in our Privacy Policy.
The Studio Beta
The Studio is the browser tool where Pro subscribers customize each library in detail. It is an early Beta: provided for evaluation and everyday use, but panels, parameters, and its behavior may change, regress, or be removed at any time without notice. We make no guarantee that it will be available, stable, error-free, or fit for any particular purpose.
Configurations and code you export from the Studio are yours to use under Using the libraries above.
The Studio agent and its monthly allowance
The Agent tab sends your request to an AI model that tunes, or rebuilds, the effect for you. Its use is limited per account per calendar month: at most 150 agent requests, and an agent-cost allowance of about $3 worth of model usage (measured in the tokens the model reads and writes). A simple tuning request uses a small fraction of a cent; a request that rebuilds an effect's core can use a few cents to around twenty. When either limit is reached the agent stops answering until the first day of the next month, while the manual controls, presets and everything else in the Studio keep working. Unused allowance does not carry over, is not refundable, and is not a quota you own — we may change the limits, and the model behind the agent, as the Beta evolves. The agent may also decline requests unrelated to the effect in front of you.
Code the agent writes (a rebuilt core) runs in your browser and, if you export it, in your app; it is provided as-is under No warranty below, and it is yours to use under Using the libraries above.
