Notes: building on a single VPS with Docker + Traefik

  • Architecture: 1 VPS, Docker Compose stacks: traefik (edge) + app containers + DB (Postgres) + Redis + optional worker.
  • Traefik: automatic TLS via Let’s Encrypt; route by subdomain (api., app., admin.). Add rate limits + basic WAF rules.
  • Data: Postgres for core data; Redis for queues, sessions, rate limiting.
  • Email: use an external SMTP (Postmark/Mailgun) to avoid deliverability issues.
  • Webhooks: isolate a worker container for calendar sync + email + reminders.
  • Observability: container logs + simple metrics (Prometheus/Grafana optional). Daily DB backups to object storage.
  • Multi-tenancy: start single-tenant, add tenant_id later; enforce per-tenant quotas.
  • Security: OAuth with Google/Microsoft, encrypted tokens at rest, least-privilege scopes, audit logs.

Quick Deploy
Clicking Create + Deploy creates a deploy job immediately (you can follow logs).
OpenBook Scheduler (Calendly-like)
openbook-scheduler
M cpu=2 ram=4GB disk=40GB
People want a self-hosted, privacy-friendly alternative to Cal.com/Calendly for 1:1 bookings with branded pages, calendar sync, reminders, and basic team features—without per-seat pricing.
TeamFlow Round-Robin Scheduling
teamflow-round-robin-scheduling
L cpu=4 ram=8GB disk=60GB
Sales/support teams need fair distribution of meetings (round-robin) with pooled availability, routing rules, and shared event types—often the missing piece in simpler schedulers.
PayMeet — Scheduling with Payments & Deposits
paymeet-scheduling-payments
M cpu=2 ram=4GB disk=40GB
Coaches, consultants, and service providers want bookings that require payment (or a refundable deposit) to reduce no-shows and automate invoicing.
Schedulify Cloud — Multi-tenant Scheduling SaaS-in-a-Box
schedulify-multitenant-scheduling
L cpu=4 ram=8GB disk=80GB
Agencies and entrepreneurs want to resell scheduling as a white-label product (clients each get their own booking pages, branding, and staff) without building everything from scratch.
PrivateSlot — Secure Scheduling for Clinics & Legal
privateslot-secure-scheduling
L cpu=2 ram=4GB disk=60GB
Clinics, therapists, and legal practices want privacy-first scheduling with minimal data exposure, secure links, encryption, and strong audit trails—often avoiding mainstream schedulers for compliance concerns.
HireSlot — Recruiting & Interview Scheduling
hireslot-interview-scheduling
L cpu=4 ram=8GB disk=80GB
Recruiters and hiring managers spend significant time coordinating interviewer availability, time zones, and video links; a focused tool beats generic schedulers for interview loops.
TutorTime — Classes, Tutoring & Recurring Sessions
tutortime-recurring-scheduling
M cpu=2 ram=4GB disk=50GB
Tutors and small schools need recurring bookings, packages, parent/student coordination, and attendance tracking—features general scheduling tools often under-serve.
ResourceReserve — Rooms, Desks & Equipment Booking
resourcereserve-room-equipment-booking
M cpu=2 ram=4GB disk=40GB
Offices, studios, makerspaces, and clinics need resource-based scheduling (rooms/equipment) with rules and check-in—adjacent to Cal.com but with different constraints.
ConciergeCal — Email-to-Booking Assistant
conciergecal-email-assistant
L cpu=4 ram=8GB disk=80GB
Many professionals want a lightweight assistant that proposes times, handles rescheduling, and confirms bookings from email threads—reducing back-and-forth more than a simple link.
FieldService Booker — In-person Appointments with Travel Buffers
fieldservice-booker
L cpu=4 ram=8GB disk=80GB
Home services (repair, cleaning, inspections) need scheduling that accounts for travel time, service areas, and technician routing—something generic Cal.com-style tools don’t handle well.
