Rectangle vs Reloop

Rectangle is a macOS utility for moving and resizing windows with keyboard shortcuts or snap areas. Repeating a shortcut cycles through window sizes, while dragging a window to a screen edge or corner snaps it into place; portrait display layouts are supported. The free Rectangle plan is open source under the MIT License and supports macOS 10.15 or later on Intel and Apple Silicon. Rectangle Pro adds a one-combination control that can move a window to any of 16 sizes and positions, even when it is not focused. Users can create custom snap targets with a chosen size, position, and repeated-command behavior. Pro can arrange app workspaces with one shortcut and activate them when displays connect or disconnect. It can sync configuration over iCloud and load shortcuts from Rectangle. Pro supports macOS 13.5 or later on Intel and Apple Silicon, with older versions listed separately; one license can be active on up to three devices at once. Rectangle’s privacy policy says it gathers no user data.

Reloop is an email delivery platform for transactional and programmatic workflows, available as hosted plans or self-hosted on infrastructure you control. It provides a transactional API and SMTP relay, plus webhook-based inbound routing and dedicated agent inboxes. First-party SDKs support Node.js, TypeScript, Python, Go, Rust, PHP, and Ruby; listed framework integrations include Next.js, Django, Ruby on Rails, and Laravel. Analytics cover delivery, opens, clicks, bounces, complaints, SMTP responses, and reputation. Templates support AI-assisted generation, editing, previews, variables, and version history. Hosted plans retain data for 45 days and set limits for inboxes, webhooks, and custom domains. The Free plan allows 3,000 emails per month and 100 per day; sending pauses when either cap is reached. Pro costs $10 a month for 50,000 emails per month, with overage at $0.50 per 1,000 emails. Self-hosting has no Reloop license cost, though server and delivery costs still apply. Reloop is open source under Apache 2.0 with Reloop Labs use restrictions.
