Why this score
Not enough measured signals for Owner-safe, and the score is outside the Needs-a-techie band. Captured 2026-10-15. Unmeasured signals add nothing and are not treated as failures.
Alive14/20
- Last push. 8 points. GitHub pushed_at was 0 days before 2026-10-15.
- Releases in 12 months. 6 points. The public releases feed shows at least 10 tagged releases in the last 12 months.
- How fast issues close. Not measured. Median issue-close time is not in the seed snapshot, so this signal is omitted.
Trusted1.4/20
- OpenSSF Scorecard. Not measured. No Scorecard result in the snapshot.
- Open critical or high vulnerabilities. Not measured. Open vulnerability counts were not fetched. We do not assume zero.
- Contributors in 90 days. Not measured. 90-day contributor counts were not fetched.
- Bus factor. Not measured. Contributor share was not fetched.
- Stars. 1.4 points. 826 stars, log-scaled and capped at 20,000.
Takeoverable11.3/25
- Licence. 7.5 points. Licence class copyleft.
- Stack. 3.8 points. PHP. TypeScript, JavaScript, Python, Go, PHP, and Vue score as widely hireable.
- Tests and CI. Not measured. We did not confirm a test suite. Missing CI at the usual paths is treated as unknown, not as a failure.
- Docs quality. Not measured. Docs quality is an LLM rubric. v1 does not invent that score.
- Data export. Not measured. Data-export was not audited app by app, so it is omitted.
Easy to run5/20
- One-click deploy. Not measured. No one-click host was verified for this app, so the signal is omitted rather than scored as a failure.
- Managed cloud or done-for-you. 5 points. SeatLess offers done-for-you setup. A vendor cloud, where listed, is the vendor’s own hosting, not a licence you own.
- Docker Compose. Not measured. No Dockerfile or Compose file at the usual paths. It may still exist elsewhere, so this is omitted.
- Memory needs. Not measured. Memory needs were not measured.
- Setup steps. Not measured. Setup-step rubric was not run.
Feature fit4.5/15
- Coverage of the incumbent’s main jobs. 4.5 points. Editorial reading of public docs. Not a certified feature audit. Unknown jobs are left out of the average.
What it replaces
LibreBooking is a PHP app for reserving rooms, equipment, and other resources. It is GPL-3.0. It belongs in scheduling because owners search for it here, and it will disappoint you if you wanted a Calendly link.
Feature coverage vs Calendly
Editorial, from public descriptions. A dash means we did not assess that job. This is not a lab test, and Calendly has not reviewed it.
