About

Semaphore Remote

Features
Read full description

Semaphore Remote is an app for users who manage automation with Semaphore UI and need quick access to their tasks from a mobile device. Connect directly to your Semaphore server using a personal API token, browse projects and templates, launch new executions, monitor running tasks, and read raw task output when something needs attention. The app is designed for DevOps workflows where speed and simplicity matter. You can open a project, review available templates, start a run, force an execution when needed, check recent tasks, follow active jobs, and quickly jump to fatal messages, errors, warnings, or the last line of a log. Key features: โ€ข Connect to Semaphore UI using a personal API token โ€ข Browse projects, templates, and task history โ€ข Launch tasks from templates โ€ข Force task runs when needed โ€ข Monitor running, waiting, and pending tasks โ€ข Receive local notifications when monitored tasks finish โ€ข Read raw task output with line numbers โ€ข Search inside logs โ€ข Jump quickly to fatal, error, warning, or last-line matches โ€ข Share task logs as text files โ€ข Supports English and Italian Semaphore Remote does not require an external account and does not use tracking, analytics, or advertising. The app communicates only with the Semaphore server configured by the user. The server URL and API token are stored locally on the device and used only to authenticate requests to your Semaphore UI instance. Note: Semaphore Remote is intended as a mobile companion tool for quick checks and interventions. Local notifications depend on system background behavior and are not a replacement for server-side alerting.

Difftray brings code review to your phone and tablet. Pair it with the open-source Difftray desktop app, then read git diffs, browse every changed file, and leave line-by-line comments โ€” all over your own local network, with no cloud in between. Difftray is a companion app. It works alongside the Difftray desktop app running on your Mac. Scan a QR code once to pair, then pick up any project from the couch, a meeting room, or the other side of the office. REVIEW DIFFS ANYWHERE Read inline diffs with real syntax highlighting, sized for small screens. See additions and deletions at a glance, move between changes, and mark each file reviewed as you go. BROWSE CHANGED FILES Step through every changed file in a project and see exactly what moved, with per-file and total added/removed line counts. HAND OFF TO YOUR CODING AGENT Leave comments on the lines that need work, then export them as an agent-ready prompt. Copy it or share it straight into your AI coding agent so the fixes are queued up before you're back at your keyboard. ALL YOUR PROJECTS Every project open on your desktop is one tap away on your phone or tablet. PAIR LOCALLY, STAY PRIVATE Connect by scanning a QR code or entering a short code โ€” no account, no sign-up. Your phone talks directly to your own computer over local Wi-Fi, or over your private Tailscale network when you're away from your desk. Pairing is end-to-end encrypted, and your code never touches a server we run. REQUIREMENTS Difftray requires the free, open-source Difftray desktop app with its companion server enabled. This mobile app is a companion to that desktop app and does not work on its own. Pair your phone, step away from your desk, and keep reviewing.
