Overview
Cloudlog is a free, open-source amateur radio logging application built with PHP and MySQL, created by Peter Goodhall (MM9SQL) as a hobby project for the amateur radio community. It lets operators log contacts from any web browser, covering HF through microwave.
The software can be self-hosted for free on a server with PHP and MySQL/MariaDB, or run through a paid hosted subscription offered by its creator for operators who prefer not to manage their own server.
Key Features
Cloudlog integrates with radio equipment via CAT control, syncs logs automatically from WSJT-X, and supports satellite operation through SatPC32. It offers full Logbook of the World integration with automated upload and matching, plus eQSL and QRZ Logbook syncing, awards tracking for DXCC, WAS, VUCC, IOTA, DOK, and SOTA, and analytics including QSO graphs and a grid-square map.
Pricing
Self-hosting Cloudlog is completely free and open source. A paid hosted subscription is available from the creator starting around £4/month or £48/year, covering 24/7 uptime, automated backups, and 5GB of QSL/eQSL card storage.
Key Features
Browser-based logging — Log contacts from any device with a browser and internet connection, no desktop software required.
CAT control — Interfaces directly with amateur radio equipment for real-time frequency and mode tracking.
WSJT-X sync — Automatically syncs digital-mode contacts logged in WSJT-X.
LoTW, eQSL & QRZ integration — Automated upload and confirmation matching with Logbook of the World, eQSL, and QRZ Logbook.
