About AllinSSL

AllinSSL is an all-in-one tool for the lifecycle of SSL certificates. It combines applying for certificates, managing them, deploying them to services and monitoring expiry in a single application with a visual interface, so site operators do not have to chain together separate scripts and cron jobs.

It supports certificate authorities including Let's Encrypt, ZeroSSL, Google, SSL.com and BuyPass through the ACME protocol, and highlights fully automated application and renewal, deployment to multiple platforms such as CDNs, web application firewalls, control panels and cloud storage, certificate expiration monitoring and secure entry protection. It runs on Linux, with notes about macOS and Windows, and is built with Go and TypeScript. Documentation exists in Chinese, and a roadmap invites suggestions via GitHub issues.

AllinSSL is licensed under AGPL-3.0 and runs on your own server. It suits administrators handling many domains who want renewals handled automatically, and teams that deploy certificates to several CDNs or panels from one place.
