What CertifiCat is
CertifiCat is a self-hosted certificate generation and management tool for event organisers. It can run on your server under your domain, and its admin panel lets organisers add events, upload their own templates and produce certificates for multiple events. Recipients can retrieve certificates from a download page by entering a certificate code or user ID. The project is open source, licensed under AGPL-3.0 and free to use. Its setup relies on Firebase for authentication and database services, with email and password authentication configured for the admin user. MongoDB stores the template base PDFs, so a running MongoDB instance is required. Setup also calls for a Firebase project on the Blaze plan with Firestore and Storage enabled. The README advises disabling Firebase sign-up to prevent other users from creating accounts. Installation involves cloning the repository, installing dependencies with Yarn, building the project and starting the server. The listed CertifiCat plan is free, with no paid tiers or usage limits stated.
