What Frabs does
Frabs is a server logging and activity replay platform. You install a small agent on your server. The agent collects raw logs from every source — auth logs, syslog, Nginx, PHP, MySQL, Docker, and more — and sends them to Frabs every few seconds.
Frabs stores those logs and also parses them for important events: SSH logins, service restarts, package installs, errors, reboots. These events form the Server Replay timeline.
When something goes wrong on your server, you open Frabs Console and see exactly what happened — in order, with context. No digging through SSH sessions or piecing together log files manually.
Server Replay
Server Replay is a simplified timeline of important events on your server. It shows what changed, what failed, who logged in, and what restarted — in chronological order.
Replay events are stored for 30 days. You can filter by event type, severity, source, and time range. When a sequence of events suggests a likely cause, Frabs shows a plain-English explanation.
Raw Logs
Raw logs are every individual log line from your server, stored verbatim. They are searchable by text, IP address, service, log level, and time range. Raw logs are stored for 7 days.
You can use raw logs for deep investigation when the Replay summary isn't enough. Live tail streams raw logs in real time as they arrive from your server.
Alerts
Alerts fire when specific conditions are met on your server. You can create alerts from the Alerts section in the Frabs Console. Each alert has a cooldown period (default 30 minutes) to prevent spam.
Alert notifications are sent by email and shown as in-console notifications.
Billing
Frabs charges £2.99 per server per month. One active subscription with a quantity equal to the number of servers you want to connect. Adding more servers increases the quantity.
Billing is handled by Stripe. You can manage your payment method, view invoices, and cancel through the Stripe Customer Portal accessible from Billing settings.
Uninstall the Agent
The uninstall script stops and disables the frabs-agent service, then removes all agent files. It will ask before deleting your configuration and local log buffer.
