Ops & productivity
Flat-Workspace Team Scheduler
One-command self-hosted team scheduling with unlimited seats at one flat workspace price, plus an instant hosted trial that exports to self-host.
In plain English
- What category is this?
- Owners and teams buy to run day-to-day work — scheduling, projects, HR, ops. Here the focus is team scheduling.
- The idea, briefly
Build a single-binary, one-command self-hostable team scheduler with unlimited seats at one flat workspace price, paired with an instant hosted trial that one-click exports to self-host, aimed at 5-30 person teams and regulated shops that will not run a multi-service stack.
More ▾- What buyers expect
People comparing tools like Calendly, Cal.com expect the basics to work without surprise fees or missing pieces. The loud complaints are: Per-account seats block embedded use; and small teams reject both self-hosting and small per-seat discounts.

Should you build this?
People already pay for this per-seat ($10-16/seat/mo Calendly, $12/user/mo Cal.com Teams, $15k/yr Enterprise floor) at large reported scale,: per-account seats kill embedded use, small teams reject both server management and trivial per-seat discounts, and self-host onboarding needs manual database surgery. But Calendly owns the brand default with a two-sided network effect and Cal.com owns the open-source funnel at 48.5k stars, so a flat-price clone with no distribution wins nothing.
