LogSure

Analytics, errors and support for every app you run.

Self-hosted, open source and cookieless, with tracing, A/B tests and feature flags built in.

Get started View on GitHub
An app's dashboard in the LogSure web console: visitors, visits, pageviews, bounce rate and visit duration over 30 days, a chart with a spike in mid-October, and the top pages and sources.

One console for all of them.

Every app you point at LogSure gets its dashboards, errors, traces and experiments. The inbox and the waitlist cover them all.

  1. See what is working.

    Visitors, pages, sources, countries, devices and goals. Click any row to filter by it.

  2. Catch every error.

    Grouped into issues, scrubbed, with the line of your code it starts in. Resolve it; if it comes back, it opens again.

    Learn more about errors
    An app's open errors with their sparklines, events and users.

  3. Follow the request.

    OpenTelemetry traces and logs over OTLP: a waterfall per trace, a live log tail, p95 per service.

    Learn more about tracing
    A checkout request as a waterfall of 13 spans across four services.

  4. Test, then ship.

    A/B experiments and feature flags without cookies, with uplift, intervals, rules and a kill switch.

    Learn more about the Lab
    An experiment's results: the green button ahead of the blue control.

  5. Read every bug report in context.

    Steps, version, browser, device and page arrive with the report. Reply, note, resolve.

    Feedback and bug reports The inbox
    A bug report in the inbox: its steps, the expected result and details such as the version, browser and device.

  6. Grow a waitlist for each app.

    Lists, signups per day, invited and joined. Your form, your list, your data.

    Learn more about waitlists
    The waitlist: signups for three sample apps by list and status, and signups per day over 90 days.

Bring the team.

Invite people as admins, members or viewers, limit each to the apps they work on, and see who changed what in the audit log. Sign in with a passkey.

Teams and sign-in
Settings, Team: five people with their role, the apps they may see, two-factor and when they were last seen, an open invite and the audit log.

Counts visits, not people.

No cookies, no IP addresses kept, and the salt behind each daily visitor code is deleted after a day.

How privacy works
0cookies, and nothing stored on the visitor's device
24hours a visitor salt lives before it is deleted, backups included
256bit AES-GCM key sealing email addresses at rest
149API operations, in one OpenAPI contract

One binary. Runs anywhere.

The Rust engine and the web console in one container. SQLite out of the box, with Postgres and MySQL on the way.

Try it in a minute

PASSWORD=$(uuidgen); echo "Password: $PASSWORD"
docker run -d --name logsure -p 8080:8080 -e ADMIN_PASSWORD=$PASSWORD \
  -e CONSOLE_HOST=localhost:8080 -e COOKIE_SECURE=0 ghcr.io/logsure/server

Open http://localhost:8080 and sign in with any username and the password it printed. Its data goes when the container does.

Keep it running

export ADMIN_PASSWORD=$(uuidgen) DATA_KEY=$(openssl rand -hex 32)
echo "ADMIN_PASSWORD=$ADMIN_PASSWORD DATA_KEY=$DATA_KEY"   # keep both
docker run -d --name logsure --restart unless-stopped -p 8080:8080 -v logsure-data:/data \
  -e ADMIN_PASSWORD -e DATA_KEY -e CONSOLE_HOST=localhost:8080 \
  -e COOKIE_SECURE=0 -e TRUST_PROXY=0 ghcr.io/logsure/server:latest

Data in the logsure-data volume, email addresses sealed with DATA_KEY, restarts with Docker. Replace a quick-start container first with docker rm -f logsure. On a domain with HTTPS: Getting started.
