Everything You Need to Log Your Contacts

Powerful features designed for serious amateur radio operators

🛰️

Built for satellite logging

Cloudlog focuses on getting satellite QSOs right in your logbook. Log the satellite name and mode, filter statistics and grid maps by satellite, and see VUCC summaries on the dashboard (including satellite contacts). Export satellite QSOs to LoTW, and use built-in Hamsat and pass timer pages that show data from external services at your grid. Cloudlog does not predict passes itself; pair it with your usual tracking software, including through Aurora.

Web-Based Interface

Access your logbook from anywhere with a modern, responsive web interface. No desktop software required.

Self-Hosted & Secure

Keep complete control of your data by hosting Cloudlog on your own server or shared hosting.

Real-Time Lookups

Instant callsign lookups using QRZ, HamQTH, and other services. Auto-populate QSO details as you log.

Multi-Station Support

Manage multiple stations, locations, and radio configurations all from one installation.

Built-In Bandmap

Visual bandmap display of cluster spots, just like your desktop apps. See band activity at a glance and spot rare DX.

LOTW & eQSL Integration

Upload and download directly from your browser. No TQSL desktop app needed! Cloudlog handles LOTW, QRZ Logbook, Clublog, and eQSL seamlessly.

DX Cluster Support & Spotting

Connect to DX Cluster networks for real-time spotting and band activity. See rare DX spots, check if callsigns have been worked, and enhance your DX hunting through the built-in bandmap and cluster connections.

Awards Tracking

See your progress towards DXCC, WAS, IOTA, and other popular awards from the contacts in your logbook.

Statistics & Analytics

Visualize your radio activity with detailed statistics, maps, and charts. Generate monthly activity reports and filter by custom date ranges for contests and activations.

Import & Export

Import from ADIF files or export your logs. Compatible with other popular logging software.

Personal Data Backup & Restore

Create complete backups of your station data, logbooks, and QSOs in a single JSON+ZIP file. Preview before restoring to manage conflicts safely.

OQRS - Online QSL Request System

Our Story

Born from a Real Need

Every great project starts with a problem that needs solving. For Peter Goodhall, MM9SQL, that problem was managing logs across multiple radio shacks and locations.

💡

2010 - The Beginning

Cloudlog started life as "HRD Frontend", created to provide a web frontend to the Ham Radio Deluxe logbook MySQL database. Peter needed a way to log QSOs whilst operating from G4AZN, G6PZ, and other locations when he wasn't at home. The problem: no unified logging solution that worked everywhere.

Cloudlog Logo

2011 - A New Name

Gavin, M1BXF, convinced Peter to rename the project "Cloudlog", a name that better captured the essence of cloud-based amateur radio logging. The project began to take on its own identity, independent of any desktop application.

🚀

2020 - LoTW Breakthrough

A major milestone: Cloudlog became one of only two online services capable of uploading directly to Logbook of the World. This breakthrough eliminated the need for desktop TQSL software and positioned Cloudlog as a truly comprehensive web-based logging solution.

🌍

Today - A Global Community

What started as a personal tool has evolved into a comprehensive logging platform used by operators worldwide. With contributions from developers and enthusiasts globally, Cloudlog continues to innovate whilst remaining free and open source for all.

Bridge the Gap Between Hardware and Web

Cloudlog Aurora is the desktop companion application that connects your physical radio equipment and favourite desktop applications directly to your Cloudlog installation. It runs on Windows today, with Mac and Linux versions coming soon.

📻

Radio Control (CAT)

Connect your transceiver directly to Cloudlog. Automatic frequency, mode, and band detection as you tune across the bands. Aurora uses Hamlib to provide comprehensive radio support.

🛰️

Satellite software integration

Link SatPC32 or CSN Technologies S.A.T. through Aurora so satellite name and grid details flow into Cloudlog while you operate. Aurora carries data from your tracking setup; it does not predict passes for you.

💻

WSJT-X Integration

Seamlessly log FT8, FT4, and other digital mode contacts from WSJT-X directly into Cloudlog in real-time.

🔗

Application Bridge

Acts as a bridge between desktop logging applications and your web-based Cloudlog, giving you the best of both worlds.

⚡

WinKey Support

Key CW from Aurora with WinKey-compatible interfaces, so your station and Cloudlog stay in step when you are sending Morse.

🔄

Rotator Control

Point your beam from Aurora when your rotator is connected, keeping antenna heading alongside the rest of your station data in Cloudlog.
