Overview
In a world where file sharing often means uploading to a cloud server, just f*ing send it** (jfsendit) takes a radically different approach: it connects two browsers directly over an encrypted WebRTC channel. Drop a file (or an entire folder), get a short code, share it, and the data streams straight from your device to the recipient’s – no upload, no server, no account. Multi-gigabyte files work, and transfers can resume if the connection drops.
Very Good Calendar Sync is a macOS app that sits quietly in your menu bar, keeping events from one calendar automatically synchronized to another. It runs fully locally, never transmits your calendar data to an external server, and supports Google, Microsoft, Apple iCloud, and any CalDAV calendar. The first sync is free; paid plans unlock unlimited synchronisations.
While these two products serve completely different use cases, they share a strong emphasis on privacy, local control, and simplicity. This comparison breaks down their features, pricing, and ideal use scenarios.

Pricing
just f*ing send it** is completely free. There are no accounts, no servers, and no limits on file size or number of transfers. The service is supported by its creator as a public good.
Very Good Calendar Sync offers a generous free tier that covers one synchronization between two calendars. If you need more (e.g., syncing work, personal, and client calendars), you choose a plan inside the app:
- Monthly: $3.99 – cancel anytime.
- Yearly: $39.99 – save over 15% vs monthly.
- Lifetime: $99.99 – one payment, all future updates included.
All paid plans include unlimited synchronisations, all calendar providers, and email support. The license is per user for all your Macs.
Pros and Cons
just f***ing send it
Pros:
- Fully free with no restrictions on file size or transfer count.
- No account or installation required – works entirely in the browser.
- Files never touch a server; maximum privacy and security.
- Supports whole folders and resume on dropped connections.
- True end-to-end encryption via WebRTC.
Cons:
- Requires both sender and receiver to be online simultaneously.
- No persistent storage; link/code expires after use.
- No ability to scan or moderate files (must trust the sender).

Very Good Calendar Sync
Pros:
- Eliminates double-booking by keeping calendars in sync automatically.
- Runs entirely locally – no third-party server, no data collection.
- Works with all major calendar providers (Google, Microsoft, Apple, CalDAV).
- Flexible sync rules (weekdays, time range, event detail redaction).
- Free tier covers one sync; paid plans are affordable and include lifetime option.
Cons:
- macOS only; no iOS or Windows support yet.

- Requires initial setup and calendar account credentials.
- Paid plans needed for more than one sync pair.
Verdict
just f*ing send it** is the perfect tool for anyone who needs to share a large file quickly and privately without any cloud intermediary. Its lack of accounts, server storage, and file size limits makes it ideal for developers, journalists, or anyone who values privacy above all else. The trade-off is that both parties must be online simultaneously, and the code expires after one use.
Very Good Calendar Sync is a must-have for macOS users who juggle multiple calendars and want a simple, secure way to keep them aligned. Its local-only approach means your sensitive meeting data never leaves your machine, and the flexible sync rules let you control exactly what gets shared. The free tier is generous enough for one sync pair, and the paid plans are reasonably priced for the convenience and peace of mind.
Ultimately, these products serve different purposes, but both excel at their core mission: providing powerful functionality while respecting your privacy and keeping control in your hands.
