Maloja's one job is to be your own scrobble database, charting what you listen to from a server you control. Players and media servers that speak the native JSON API or a ListenBrainz, GNU FM, or Audioscrobbler 1.2 compatible protocol can scrobble with their own API keys. Vinyl sessions and background music can be logged by hand on a manual scrobble page. Existing history moves in from a Last.fm export, a Spotify data export, a ListenBrainz export, or another Maloja instance, while a proxy option forwards new scrobbles to Last.fm or a second Maloja server. The start page ranks top artists, tracks, and albums for today, this week, this month, this year, or all time, alongside a pulse chart of listening volume and a feed of the latest scrobbles. Artist and album pages add performance charts that follow chart position over time. Collaborations credit every artist on a track, and subunits, solo projects, and main acts can be combined or separated in charts at any time. Gold, Platinum, and Diamond awards mark tracks and albums that pass scrobble thresholds you set. Artwork can come from Last.fm, Spotify, Deezer, TheAudioDB, or MusicBrainz lookups, or from images you upload yourself. Week start, timezone, theme, and tile layout are all settings, and an API explorer lists endpoints for scripts.

Try an idea in React, Svelte, Python, or SQL without installing anything: LiveCodes is a browser-based playground where code compiles, runs, and previews the moment you type it. Starter templates open ready-made projects for most of the 90+ supported technologies. The desktop editor brings completion, multi-cursor editing, Emmet, and Vim or Emacs bindings, while a lighter touch-friendly editor takes over on phones and tablets. Packages from npm, deno.land/x, jsr, and GitHub import straight into your code, and a console, compiled-code viewer, and test runner show what happens behind the preview. Bring projects in from GitHub gists, GitLab snippets, JS Bin, or zip files, then share them as links or QR codes, export them as HTML, JSON, or zip archives, or send them to CodePen and JSFiddle. Deploy a project to a public URL on GitHub Pages, sync your work across devices, or broadcast your editor and result live to a classroom. An embed builder and SDKs for JavaScript, React, Vue, Svelte, Solid, Preact, and web components place playgrounds inside documentation pages, and prefilled code makes every example editable. Projects stay private by default. Local assets, snippets, themes, and dark or light modes tailor the workspace to each person.

Mixpanel, OneSignal, and Crashlytics in one self-hosted stack - Countly is an all-in-one product analytics and engagement platform where every byte of first-party data stays on your server. A Node.js application over MongoDB, it collects through ten battle-tested SDKs spanning iOS, Android, web JavaScript, React Native, Flutter, Unity, and desktop (plus a data write API for anything else), and has powered tens of thousands of mobile, web, and desktop apps since 2012. The analytics core covers sessions, custom events, views, user profiles, and real-time dashboards, with exploration tools built for product managers as much as analysts. What separates Countly from pure analytics tools is acting on the data without third parties: built-in push notifications send automated, transactional, and personalized messages to iOS (APNs), Android (Firebase), and Huawei devices, with the SDK handling token retrieval and permission flows automatically; crash reporting captures symbolicated native crashes on iOS and Android plus JavaScript errors, correlated with the same user and session data. Email reports keep stakeholders updated, and the plugin-based architecture means features load as modules. For GDPR-sensitive products, engagement without piping user data to advertising companies is the entire point. AGPL-licensed server, installable in minutes.

A fast, read-only radar for outdated Docker images. Cup reads the images behind your running Docker or Podman containers, asks each registry whether a newer digest or tag exists, and flags every result as a major, minor, or patch bump, a plain digest change, or up to date. Docker Hub, ghcr.io, Quay, lscr.io, and Gitea-style registries are supported, private ones through token authentication, and checks are designed not to exhaust registry rate limits. The browser dashboard on port 8000 counts monitored, outdated, up-to-date, and unknown images, adds search and filters, and opens any image to show its update type, check time, and a copyable pull command. Prefer automation? Schedule refreshes with a cron expression, trigger one through the API, or run the cup check command from a cronjob for table or JSON output. Rules in cup.json exclude images, ignore registries, and skip chosen update types, even per image. The JSON API feeds Homepage widgets, Home Assistant, and custom dashboards, one dashboard can aggregate several Cup servers, and agent mode serves the API without the interface. Cup only reports, so deciding when to update stays with you. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console.
