Scheduling and meetings
Whereby alternatives
1 open-source project that already does this job. Free to use - not free to run, which is what the numbers on the right are for.
The projects
What you give up either way
- Globally distributed server mesh and bandwidth-optimized routing across regions
- Enterprise SLAs (99.9% uptime) and large-scale reliability guarantees
- Official compliance certifications (GDPR/HIPAA configuration and ISO 27001 certification)
- Mobile SDKs and embeddable pre-built UI with maintained docs and developer support
- Dedicated customer success and enterprise-level support included
An open-source project doing the core job proves a replacement is possible. It does not prove it matches Whereby, and it does not prove anyone has run it for a month. How we decide.
