Replace Clockwise?
NOT REALLY · don't botherA consolation build is possible, but the paid product's decisive value sits outside a solo rebuild. For Clockwise, rearrange flexible holds around fixed meetings for one user's calendar. The hard boundary is organization-wide optimization, calendar graph, team adoption, and conflict safety, plus calendar integrations and reliability.
Build a closest honest personal substitute for Clockwise in an empty repository. Use Next.js 15, TypeScript, PostgreSQL, Drizzle ORM, Google Calendar OAuth, and Resend; do not offer alternative stacks. The core loop is: read one user's calendar, rearrange flexible holds around fixed meetings, create conflict-safe bookings, and send confirmations and reminders. Make the first run work locally with one documented command. Store all user data locally by default and make export straightforward. Put secrets in .env, ship .env.example, and never commit credentials. Implement one account with configurable working hours, buffers, minimum notice, and booking horizon. Connect Google Calendar using OAuth and store refresh tokens encrypted at rest. Calculate availability in UTC and render it in the visitor's detected timezone. Reserve slots transactionally, create calendar events, and prevent concurrent double booking. Send confirmation, cancellation, and reminder email with signed management links. Add an admin booking list, event-type editor, audit log, and calendar reconnect flow. Include clear empty, loading, success, and recoverable error states. Add input validation, safe filenames, and graceful handling of unavailable APIs. Write focused tests for the core transformation and one end-to-end happy path. Create a README with setup, architecture, permissions, data location, and backup steps. Do not add accounts, billing, telemetry, analytics, or a hosted control plane. Do not claim to reproduce proprietary data, network liquidity, regulated access, or frontier infrastructure. Deliberately leave out Microsoft and Apple calendar support. Deliberately leave out team round-robin routing. Deliberately leave out payments, CRM workflows, and enterprise controls. Finish by running the tests and listing the exact commands used.

People still pay for Clockwise because people pay because one double booking or missed invite can cost more than years of subscription fees. The recurring cost buys OAuth refresh, webhooks, timezone databases, race conditions, reminders, deliverability, privacy, and uptime, not just the visible interface.
