What is CiteKit?
CiteKit is a small, one-time utility for site owners who want their public website copy available in formats that AI agents can parse. You paste a public HTTPS URL and CiteKit previews an llms.txt file, schema JSON-LD, an FAQ markdown file, and a README from that origin. You read the preview before deciding whether to buy the generated ZIP.
The product is designed for a website’s own content and is not an AI model or an agent runtime. It does not send site content to an external AI model, change search rankings, create citations, or provide monitoring. It is not a WAF or security service. The generated files are delivered for you to host and maintain; they are not a guarantee that an AI system will read or cite them. CiteKit is sold for US$19 one time per site through Paddle.
The checker fetches public pages only, does not sign in to the site, does not execute its JavaScript, and has request limits. Do not submit credentials, secrets, or URLs containing access tokens. Contact: idealstoronto@gmail.com. CiteKit is intended for developers, founders, and site owners who want a concise, honest technical brief for their own origin. It is a focused publishing aid rather than rankings, citations, monitoring, or SEO theater.
What problem it solves
Public websites often leave agents with scattered pages and no concise, machine-readable brief. CiteKit packages the site's own public copy into a reviewable set of files without promising rankings or citations.
Alternatives & competitors
Manual authoring of llms.txt, schema JSON-LD, FAQ markdown, and README files; general site generators. CiteKit is not a rankings, citations, or monitoring product.
What is Supabase?
Supabase is an open-source backend-as-a-service platform that gives developers everything they need to build an application's backend, built around the trusted PostgreSQL database. Building a backend traditionally means assembling and maintaining a database, authentication, file storage, APIs, and real-time infrastructure — a lot of undifferentiated work before you even start on the features that make your product unique. Supabase provides all of those pieces, ready to use and well integrated, so developers can focus on building their product rather than reinventing backend plumbing. It's frequently described as an open-source alternative to Firebase, but with the power and openness of Postgres at its core.
The platform centres on a full Postgres database — a mature, powerful, standard relational database, not a proprietary one — which means developers get real SQL, relationships, and the vast Postgres ecosystem rather than being boxed into a limited data model. Around the database, Supabase adds authentication with support for email, social logins, and more; file storage; auto-generated APIs so you can query your data instantly; real-time capabilities so apps can react to changes live; and edge functions for custom server-side logic. Because it's open source, teams can self-host for full control or use the managed cloud service for convenience, avoiding the lock-in that worries many developers about closed backend platforms.
Supabase has become a favourite of startups, indie developers, and teams who want to move fast without sacrificing the robustness of a real database or the freedom of open source. The appeal is speed plus solid foundations: you can stand up a production-ready backend in an afternoon, yet you're building on Postgres, which scales and won't trap you. Its excellent developer experience, generous free tier, and strong community have fuelled rapid adoption. For anyone building a web or mobile app who wants to skip months of backend setup while keeping power and portability, Supabase offers a compelling, modern foundation that has quickly become one of the most loved tools in the developer ecosystem.
