Cal.com
Cal.com is the open-source scheduling platform, an extensible Calendly alternative you can self-host or run as a hosted product, with deep routing and workflow hooks.
Best for: Teams that want Calendly-style scheduling with more control, routing logic, or self-hosting.
Cal.com covers the familiar scheduling job, sharing availability and booking meetings, but its open-source core and API make it the choice for teams that want to customize routing, embed booking deeply, or avoid per-seat lock-in. Round-robin, routing forms, and workflow triggers cover the RevOps cases that matter for inbound speed-to-lead.
For this audience the hook is that it plugs cleanly into automation: a booking can fire an n8n or Make workflow to enrich, route, and notify. Unlike Calendly, it also has a public affiliate program, which is part of why it earns a spot on the apply-first list.
