Changelog

1.2.0 — August 4, 2026 · Initial public release

First release. See every app on your Mac that reaches the internet — and stop the ones that shouldn't.

• Connection alerts — the first time an app opens a connection, Blockr holds it and asks. Allow or block, remember it as a rule or not, and scope the answer to the whole app or just that one host. One alert per app, never one per connection.
• Per-app and per-host rules — allow or block everything an app does, or name an exact host, an address, or a wildcard like *.example.com, with an optional port. Host rules outrank app rules, so you can allow an app and still cut off a single tracker.
• Live connection log — every connection with its app, remote host, port, verdict and time. Search by app, host or port, filter to just what was blocked, and sort on any column. Right-click a row to write a rule from it.
• History that survives relaunch — connections and per-app totals are kept on disk, so the monitor is never blank. Export to CSV or JSON.
• Hostnames, not just IPs — reverse DNS resolves addresses lazily, only for rows on screen, and caches the result.
• Rules manager — every rule in one screen, including apps that aren't running, plus Add App… to write a rule before an app has ever connected.
• Choose what new apps get — ask me (the connection is held while Blockr asks), or allow/block silently with no alert at all. A separate setting covers what happens while Blockr isn't running.
• Pause protection — allow everything and stop asking for 15 minutes, an hour, or until you resume (⇧⌘P). Never survives a relaunch.
• Start at login — while Blockr isn't running, unknown apps get your chosen default action.
• Optional block notifications — a blocked connection fails silently inside the app that made it, so Blockr can tell you, rate-limited to one per app per minute.
• Private by design — Blockr decides when a connection opens and never inspects, decrypts, or proxies what flows through. No account, no analytics, nothing uploaded.
• Native SwiftUI, no third-party dependencies. Menu-bar app, light + dark mode, full keyboard support, WCAG 2.1 AA.
• Signed and notarized by Apple — macOS 14+, Apple Silicon & Intel.
• Free for personal use forever, including updates; commercial use requires a one-time $5-per-device license.
