SYNCDATE is a web application for live two-way Google Calendar synchronization. Connect multiple Google accounts, select which calendars to sync, choose direction (one-way or two-way), and SYNCDATE keeps events aligned automatically in the background.
Built for professionals juggling multiple Google calendars across work, personal, and side-project accounts.
Outlook support with cross-provider sync - coming soon.

SYNCDATE's answer:
SYNCDATE treats sync as silent infrastructure โ it shows proof instead of making promises. Every sync run is logged with stats, every error comes with a deterministic fix step, and every sync can be cleanly reversed with optional event cleanup. Most calendar sync tools are black boxes. SYNCDATE exposes sync health, freshness, and latency so you can verify it's working in seconds, not just hope it is.
SYNCDATE's answer:
A generous free-forever tier (2 accounts, 2 calendars) covers the most common use case at zero cost โ competitors start at $4โ12/mo. Privacy is the default: synced events show as "busy" unless you opt in to detailed copying. And if you ever want to stop, the Clean Exit flow removes all SYNCDATE-created events from your calendars โ no orphaned copies left behind.

SYNCDATE's answer:
SYNCDATE was born from a real problem: juggling multiple Google accounts and constantly getting double-booked because calendars didn't talk to each other. Existing tools were either expensive for what they offered, opaque about what they were doing, or left orphaned events behind when you stopped using them. SYNCDATE was built to be the sync tool we wanted โ minimal, transparent, and safe to turn off.
SYNCDATE's answer:
Next.js (App Router) with TypeScript, PostgreSQL via Drizzle ORM, Redis with BullMQ for background job processing, Google Calendar API with webhook push notifications, and Stripe for billing. Deployed on a Hetzner server behind Cloudflare with a standalone Node.js worker for sync execution. Observability stack uses Grafana, Loki, Prometheus with PagerDuty for alerts.
We have been using Vercel to host some of our internally developed apps that help our team run our operations on Vercel and have found it to be a very developer friendly platform. With our apps built in Next JS it is a natural fit and the dev op pipelines can quickly and easily be configured. As these are internal apps used by our team they don't need to support huge traffic volumes so pricing has been affordable for us.

Vercel Hobby is free for personal, non-commercial projects and is built around HTTP serverless functions and static frontends. Node.js is the primary runtime, and Vercel does a lot of Next.js-specific work for you automatically: caching pages that don't change often, running lightweight functions close to the user, resizing images, and running middleware on every request. Hobby includes 100 GB of bandwidth per... - Source: dev.to / 27 days ago
Vercel is where JS-heavy Heroku apps land when the shape they really wanted was framework-native serverless, especially anything on Next.js. ISR caching, edge functions, image optimization, middleware, and the AI SDK all wire up automatically from the framework's build output, so the parts of the app Heroku was serving as HTTP handlers become serverless functions that don't pay for idle time. - Source: dev.to / 28 days ago
What went wrong: The security commit added a Content-Security-Policy Header with connect-src 'self' https://*.public.blob.vercel-storage.com. The Vercel Blob SDK's client-side upload() makes a PUT to Https://vercel.com/api/blob. That domain wasn't in connect-src. The browser silently blocked the request. - Source: dev.to / about 1 month ago
A host: A host is really just a computer that stays powered on and connected to the internet with a public address of its own. When a visitor types in the app's address, their browser sends a request across the internet to that machine, the machine runs the code, and it sends the finished page back. A laptop was quietly doing both jobs during the build, the server and the only visitor allowed in; a host is that... - Source: dev.to / about 2 months ago
The short version is this: BabyChain lets you design a ComfyUI-style media chain on a canvas, then call that same chain from product code as POST /api/v1/chains/runs. Every step executes through provider APIs with server-side credentials, every state transition persists to AWS Aurora, and Vercel functions stay stateless. - Source: dev.to / about 2 months ago
