Terms of Service
Effective 2026-10-30. By using 0saas (the site at 0saas.pages.dev or its canonical domain) you agree to these terms.
Short version: every prompt pack on 0saas is free to read and copy, forever — no login required. Some tools additionally offer a one-time-purchase unlock for a convenience feature (in-page rendering, batch export). There is no subscription anywhere on this site. You bring your own AI inference (a free-tier key or copy-paste into a chat model you already use); 0saas does not provide AI inference itself and is not a party to your relationship with that provider.
1. What 0saas is
0saas publishes a catalog of single-file "article + app" pages. Each page compares one paid feature of a named competitor ("incumbent") against a free, in-browser way to get a similar result using a prompt run against an AI model you supply. The prompts themselves — the actual instructions — are always printed in full on the page, free, with no paywall, no signup, and no rate limit from 0saas. 0saas does not host, train, or operate any AI model.
2. The one-time unlock (no subscription)
Where a tool offers a paid unlock, it is a single, one-time purchase processed through Stripe for a fixed, disclosed price — never a recurring subscription, never auto-renewing, never billed again without a new purchase. The unlock applies to the convenience layer of that one tool in that browser (for example: in-page rendering of the output, or a batch/export feature) and never gates the prompts themselves. As of this writing, 0saas's catalog has not yet enabled live payment on any tool; every page states plainly whether its unlock is live or not yet live, and no purchase can be made where it says "not yet live."
3. Device-level access, not an account
Because 0saas has no accounts, a purchased unlock is recorded only in your browser's local storage, tied to that browser/device. If you clear your browser data or switch devices, you will need to re-verify the purchase (0saas can look up your purchase by the Stripe checkout session id, not by any password). This is a deliberate trade-off for not operating a server-side user database.
4. Pricing accuracy and competitor references
Every incumbent price quoted on this site is dated and sourced to that company's own pricing page at the time it was read, published alongside a per-tool pricing-extraction record under /data/pricing/ and summarized on the public pricing receipts page. Competitor prices change; 0saas re-checks on a fixed schedule and labels numbers it could not independently verify as "unconfirmed" rather than guessing. Named incumbents (e.g. Canva, Grammarly, ClickUp, and others referenced throughout the catalog) are trademarks of their respective owners. References to them are nominative — used only to identify the product being compared — and do not imply affiliation, sponsorship, or endorsement by those companies.
5. Acceptable use
- Don't use 0saas's prompts or renderer to claim an incumbent, an AI provider, or 0saas itself endorses you or your output.
- Don't attempt to resell, scrape at scale for redistribution, or misrepresent the pricing receipts as your own research without attribution.
- Don't attempt to defeat, automate against, or abuse the Stripe verification endpoint in a way designed to obtain an unlock without payment.
6. Disclaimers
0saas is provided "as is." The in-browser renderers are a best-effort reproduction of a narrow slice of a paid feature; they are not guaranteed to match the incumbent's output exactly, and nothing on this site is professional, legal, financial, or tax advice. You are solely responsible for complying with your chosen AI provider's own terms of use when you supply a key or paste a prompt into their service.
7. Limitation of liability
To the maximum extent permitted by law, 0saas and its operator are not liable for indirect, incidental, or consequential damages arising from use of the site or its tools, beyond the amount you actually paid for the unlock in question (if any). Nothing in these terms limits liability that cannot be limited under applicable law.
8. Source code license
The code that runs this site is published under the BSD 3-Clause License in the public repository. That license governs reuse of the code; it does not grant any license to the incumbent trademarks referenced on the pages it generates.
9. Changes
These terms may be updated as the project evolves (for example, when live payment is switched on for the first time). The effective date above will change, and material changes affecting anyone who has already purchased an unlock will be announced on the public issue tracker.
