Ledge Notebook vs HiDev

Ledge is a Markdown notebook that runs the code in your notes. Write the commands for a deploy, a fix or a setup once, with the reasoning beside them, and run each block with a tap. The output appears right under the block. On iPhone and iPad, Ledge opens the notes on your own server: a Linux machine or a Mac running the free Ledge server, reached over SSH. Your notes, shells and commands stay on your machine. RUN ANYTHING • Shell, Python, Node, TypeScript, Ruby, PHP and Redis blocks run with the tools on your server • Add SQL or any other language by naming the command that runs it, such as psql or mysql • Prompt blocks hand a request to an AI agent on your server, such as Claude Code, which can read your notes • Answer a running command's prompts by typing into its output, with ^C, ^D, Esc and arrow keys above the keyboard • Each note keeps its own shell, so a cd or an exported variable carries into the next block • Give a note its own working directory, environment and secrets, kept outside the note • Run a note's blocks on another machine over SSH with one line at the top of the note • Mark a risky block to ask before it runs • A command keeps running on the server after you lock the phone, and its output is waiting when you come back WRITE AND ORGANIZE • Markdown with live preview, tables, checklists and images, including photos from the camera • Link notes to each other, with outline, backlinks and tags panels • Workspaces, folders, favorites and full-text search • Use the same notes from Ledge for Mac and from every phone and iPad you pair PRIVATE AND SECURE • You stay in control of your notes: they live on your own machine, not on our servers or anyone else's • No Ledge account, no sign-up and no third party in between • Sign in with a key made in the Secure Enclave that never leaves the device, or with a password kept in the keychain • Each server's host key is confirmed on the first connection and checked on every one after • Lock sensitive notes with a passphrase • Add a server by scanning the QR code it prints WHAT YOU NEED A Mac or a Linux machine you can reach over SSH, with the Ledge server installed. One command installs it, with no root access, no open port and no background service. The guide in the app walks you through it. Ledge is free and open source.

HiDev brings app development and business tracking into one workspace for independent developers and small teams. PLAN THE WORK Capture ideas, bugs, and feedback. Organize tasks into iterations, assign owners, and keep the next steps visible across your apps. SHIP WITH CONTEXT Build release plans from completed work, track review and launch milestones, and keep a record of what actually reached users. UNDERSTAND SALES Connect your own App Store Connect Team API key to view Apple's sales and finance reports. Review downloads, sales, estimated proceeds, product details, and release markers together. Data availability depends on your App Store Connect permissions and Apple's reporting schedule. KEEP CODES ORGANIZED Import redemption codes, track batches and assignments, and see what remains available. Full codes are encrypted on your device. YOUR WORKSPACE, YOUR DATA Start without an account or a connection. Work records stay on your device by default. Optional iCloud sync keeps your work records available across your own devices.
