RunWisp

Cron runs the line. Nobody tells you how it went.

RunWisp is an open-source cron replacement that ships as a single binary. It reads the same cron line and keeps a record of every run: output, exit code, duration.

crontab 
# crontab -e  (runs on the server's clock: UTC)
*/10 * * * *  /usr/local/bin/job.sh
runwisp.toml 
[tasks.job]
cron     = "*/10 * * * *"
timezone = "UTC"
run      = '/usr/local/bin/job.sh'
cronRunWisp
The server was off at run time Skipped. anacron only catches up cron.daily, weekly and monthly. Runs the most recent missed run at start-up (catch_up = 1) and sends a missed-run alert.
The last run is still going Starts another copy on top. Queues it. on_overlap = "queue" is the default.
A run fails Output is mailed if MAILTO and a mail server work. No output, no mail, whatever the exit code. Marked failed and sent to your alert channels. retry_attempts adds retries.

Keep your crontab. sudo runwisp takeover runs it where it is and retires cron, crontab -e keeps working, and runwisp service uninstall puts cron back. It needs Linux with systemd; elsewhere, runwisp import cron converts the file. RunWisp doesn't do L, W or #, and it runs on one machine, not a cluster. Moving from cron →
