RelayPulse
Read full descriptionHide full description
RelayPulse puts your server fleet in your pocket. SEE EVERY SERVER AT A GLANCE One screen shows the whole fleet: online, warning, stale and offline counts, plus total bandwidth. Each card carries what matters - the service you watch, connections, download and upload, CPU, RAM and disk. KNOW WHEN SOMETHING IS WRONG, NOT ONLY WHEN IT IS DOWN A server can answer while the service that matters has stopped. RelayPulse checks the systemd service you choose - a web server, a database, containers, a relay, a node - and the ports it should listen on, so you find out while it is still fixable. FLEET HEALTH A dedicated view ranks what needs attention right now and lists the busiest servers, so a hundred machines stay readable. REAL TOOLS, NOT JUST CHARTS Read service logs, see the top processes and disk usage, check the agent endpoint - over SSH, straight from the phone. Nothing runs until you confirm it. NO AGENT REQUIRED Add a server with its address and your SSH key or the server's password, and RelayPulse reads it directly. Nothing is installed on the server. An optional open-source metrics agent gives faster readings for large fleets. YOUR KEYS STAY ON YOUR PHONE Log in with an SSH key or with the server's own password, such as the root password from your VPS provider - the same choices as RelayPulse on the Mac. Create a key on the device and install it with one tap, or paste your own. Keys and passwords stay in the iOS Keychain. No accounts, no server of ours, no analytics, no ads. OPTIONAL AI DIAGNOSIS Bring your own OpenAI or Anthropic key and let the app summarise what went wrong and suggest the fix. Off by default. The key is stored in the iOS Keychain and sent only to the provider you chose, together with the error and the log lines it needs. The app never runs a command on its own. FOR RELAY OPERATORS Running Anyone Protocol relays? RelayPulse recognises them and adds relay tools - Nyx and the relay configuration - to those servers only. TRY IT FIRST Tap "Try Demo Fleet" on the first screen to explore the app with a sample fleet before adding your own servers. It is labelled as demo on every screen, and no server is contacted while it is on. FREE FOR A SMALL FLEET Monitor up to 3 servers free, with no feature withheld and nothing that expires. One purchase lifts the limit for your whole fleet. WHAT IT WORKS WITH Linux servers you administer yourself, reachable over SSH, with python3 installed - standard on Ubuntu, Debian and most distributions. RelayPulse is an independent tool. It is not affiliated with, endorsed by or sponsored by the Anyone Protocol project.
JSON Editor

Json Editor: Smart Json turns a wall of JSON into something you can actually read on a phone. The same document, three linked views. Edit in any of them and the other two follow ā the text is always the source of truth, so nothing drifts out of sync. EDITOR ⢠Syntax highlighting that re-tokenizes only what you typed, so it stays fast ⢠Line-number gutter, wrap and font size controls ⢠A punctuation bar above the keyboard: braces, brackets, quotes, true, false, null, indent, undo and redo ⢠Invalid JSON gets a plain-language banner naming the problem, its line and its column. Tap Go to jump the caret there, or Fix to repair comments, trailing commas, single quotes and unquoted keys automatically TREE ⢠A collapsible outline with indent guides, type badges and child counts ⢠Search across keys and values, filter by type ⢠Edit any node in place: rename, change type, reorder, duplicate, add, delete GRAPH ⢠A tidy node-link diagram, left-to-right or top-to-bottom ⢠Pinch to zoom, pan, tap a node to expand it, fit to screen ⢠Tap a node to open an editor docked right underneath it ā the graph edits as well as it browses ⢠Expand all, expand to a depth, or expand one subtree ⢠Export the graph as PNG or SVG FIND WHAT YOU NEED ⢠One find bar in every view. Text search in the editor with match case and wrap-around; structural search in the tree and graph with scope and type filters, stepping through hits ⢠JSONPath: type an expression and watch it evaluate live, tinting its matches in the editor, the tree and the graph at once. A documented subset of RFC 9535, filter expressions included COMPARE ⢠Diff the open document against a file, the clipboard or a URL ⢠Structural, not textual ā reformatting is not a change ⢠Changed subtrees are tinted in the graph, and array elements are paired by identity when they have one CONVERT ⢠Preview your document as YAML, CSV, TOML or XML, each with a plain statement of what that format cannot carry DOCUMENT ACTIONS ⢠Beautify, minify, sort keys, auto-fix ⢠Escape and unescape a JSON string literal ⢠Copy in, copy out, share, and a statistics breakdown ⢠Undo and redo everything, with one history per document shared by every view GETTING JSON IN ⢠Open files from iCloud Drive and Files, with proper open, save and rename ⢠Start a document from the clipboard or from a URL. URL requests are a GET with your own headers, and the last ten are remembered; header values are stored in the keychain, not in plain preferences ⢠A share extension accepts JSON from any app ⢠JSON5 files open too, normalized to JSON with a banner saying what that cost ⢠Imports are named after where they came from, like mydomain.com-users.json BUILT RIGHT ⢠Native SwiftUI for iPhone and iPad, with full keyboard support ⢠Light or dark, or pinned to whichever you prefer ⢠A hand-written parser that preserves key order and keeps number literals exactly as written ā no precision lost on a round trip ⢠Works entirely offline. No account, no sign-in, no analytics, no data leaves your device SMART JSON PRO The app is free, and every feature computes and shows you its result for free. Pro is for keeping that result: ⢠Extract JSONPath matches to a new document, plus query history and saved queries ⢠Text diff, jump between changes, copy as a patch, choose the array identity field ⢠Save, share or open a conversion to YAML, CSV, TOML or XML --- Terms of Use: https://mygems.app/term Privacy Policy: https://mygems.app/privacy

Verdict
The clearest difference is update cadence: RelayPulse at daily against JSON Editor's every 6 days. RelayPulse also leads on iOS requirement (15.0 vs 18.0). On price, ads, in-app purchases and device support there is nothing between them.
