FAQ

Is the Free plan actually free?

Yes. 5,000 log lines a day kept for 2 days, 12 assistant messages a day and 1 GitHub repository, with no card and no trial clock.

Which languages are supported?

Python and Go have official libraries (pip install justlog3, go get github.com/OAzizjon/justlog3/go) that batch, retry and keep a local log file. Anything else that can send an HTTPS POST works through the HTTP API: Node.js, Bash, PHP, a cron job or a Raspberry Pi.

Do I need an agent or a config file?

No. A library call or a POST request is all it takes; there is no daemon to install.

What happens when the cloud can't be reached?

The libraries keep writing your local log file, hold unsent lines in memory (up to 10,000 per logger) and resend them later with the same sequence number, so nothing is stored twice.

Does the AI see all my data?

Only what you switch on for that chat: logs, tasks or GitHub. Everything it reads is treated as untrusted data, so a crafted log line can't take it over. See AI assistant.

What can the GitHub integration touch?

Nothing it could break. The GitHub App is read-only: contents, pull requests, checks and Actions for the repositories you pick.

How long are logs kept?

2 days on Free, 5 to 14 days on Starter and 5 to 30 days on Expert, chosen on the billing page. See Plans and limits.

How do I pay?

In crypto through NOWPayments, monthly or yearly. Nothing renews automatically: when a plan ends it keeps working for 3 more days, and you get a Telegram reminder.

Nothing shows up in my logs. What should I check?

• The URL: the libraries send to JustLog3 Cloud by default; a url= (Python) or WithURL (Go) pointing somewhere else sends your logs there instead.
• 401 Unauthorized: the token is wrong or was rotated. Set the current token and restart.
• 429 Too Many Requests: today's line limit is spent or the client sends more than 120 requests a minute.
• Go: make sure justlog3.Shutdown() runs; log.Fatal and os.Exit skip deferred calls.
