herbstluftwm vs Reloop

herbstluftwm is a manual tiling window manager for the X window system. Each virtual desktop, called a tag, has a tiling layer and a floating layer, allowing windows to occupy split frames or be placed freely. Frames can be divided into further subframes or filled with windows, and keyboard controls move, resize, and focus tiled and floating windows. Configuration runs through herbstclient and can be changed while the manager is running without a restart. Screen space can be divided into virtual monitors that need not match physical displays; monitors share a common pool of tags. The project is licensed under the Simplified BSD License and is listed as free at free. The download page lists packages for Linux distributions and Mac OS X via MacPorts, and confirms operation on Cygwin. The project also offers released source tarballs and links to its current development version. Community help is available through IRC, Reddit, GitHub issues, and a mailing list.

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.
