Project and task management decision
Doodle
Build a basic scheduler yourself if you only need core booking and polls; keep paying for Doodle if you need enterprise security, SSO, SLA, branded pages, payments, or their AI time-intelligence.

Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All Doodle alternatives, with the arithmetic →
What a replacement has to do
- Allow a meeting host to publish availability, let invitees pick a slot (or vote), merge participants' busy signals from calendars, and write confirmed events to calendars
What it still won’t have
- Enterprise SSO (SAML/OIDC) and org admin console
- SOC 2 / HIPAA attestation and enterprise security guarantees
- 99.9% SLA / priority support and enterprise-grade reliability
- Branded booking pages, org-wide policies, and built-in payments/Stripe integration
- AI time intelligence and engagement analytics
What remains hard
- Compliance and regulation
From SOC 2 to HIPAA, Doodle meets the standard your organization demands, because ambient intelligence requires absolute data trust.
- Infrastructure at scale

Keep paying
Paying is—cheaper in year one.
On cash alone, building overtakes the subscription at 3 seats.

What we assumed
The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a minimal self-hosted meeting scheduler using Node.js (Express) + React, Postgres, and Redis: implement OAuth calendar connections for Google and Microsoft (read busy, create events), an availability merge engine honoring buffer/focus rules, a public booking page per user, simple group-poll flow (propose times + votes), webhooks/notifications and ICS invites; out of scope: SAML/enterprise SSO, paid Stripe integration, and SLA/enterprise compliance. Include error handling, retry logic for calendar API calls, CI tests for availability logic, and Docker deployment scripts.
How we checked
How the score was reached
- Partly verdict base52
- An open-source build was found+5
- 4 cited sources+3
- Price verified on pricing page+3
- Hard moats found in the evidence-6
- Evidence score57
The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
