Zencal?

KINDAYou can build the valuable core, but the established product has meaningful operational complexity. Pick one narrow promise for v1.

BUILD FIRST

One specific customer type and one primary use case
A vertical slice that completes the main job without manual workarounds
Visible limits, review steps, and a fallback when an external dependency fails

LEAVE FOR LATER

Broad third-party integrations
High-scale collaboration, syncing, and permissions
Automation that can cause harm without human review

RESEARCHED BUILD PROMPT

Give this to your coding agent.

Build a focused replacement for Zencal based on this official public description: “Zencal. Sales system for service businesses — Reach the right clients, build trust and connect every sale with the next step. Bookings, payments, events, bundles and automations in one system.” Do not copy the original brand, proprietary assets, name, logo, UI, or copy; create an original visual system.

Build only the narrow workflow described by the source. Requirements:
- define availability and timezone
- provide a conflict-safe booking page
- show confirmation/cancellation
- keep provider adapters explicit

Out of scope for v1: feature-for-feature parity, broad integrations, proprietary data infrastructure, and unverified enterprise reliability. Use a small React/TypeScript app with a portable JSON or SQLite model, explicit loading/empty/error states, and adapters around external services. Seed demo data so the workflow works without paid credentials. Include a README with setup, environment variables, data model, implementation decisions, privacy behavior, tests, and important limitations.
