Show HN: AiSyncing – Back up your AI coding assistant memories to GitHub

AiSyncing, a new open-source tool by DiegoSalazar, automatically backs up AI coding assistant memories, configs, and instruction files to a private GitHub repository daily. It supports Claude Code, OpenAI Codex, Gemini CLI, Cursor, and custom tools, with features like auto-setup, configurable include lists, scheduled sync via macOS LaunchAgent, and native notifications. The tool addresses the risk of losing persistent local data from AI assistants by syncing to a private repo for easy restore.

Automatic daily backups of your AI coding assistant memories, configs, and instruction files to a private GitHub repo. Supports Claude Code , OpenAI Codex , Gemini CLI , Cursor , and any custom AI tool you add. Multi-tool : backs up multiple AI harnesses simultaneously Claude, Codex, Gemini, Cursor, Windsurf, or anything with a local config directory Auto-setup : interactive setup.sh detects installed AI tools, creates a private GitHub backup repo, and configures everything Configurable allow list : per-source include patterns in config.json control exactly which files get backed up. Sane defaults for the top AI tools out of the box. Daily scheduled sync : macOS LaunchAgent runs at your chosen hour. Each commit shows which sources changed: sync claude,codex : 2026-08-24 15:00:00 Native macOS notifications : a compiled Swift helper app shows banner notifications on each sync. Click to open your backup's commit history on GitHub. Restore anywhere : clone your backup repo on a new machine and rsync the data back AI coding assistants store persistent memories, custom agents, instruction files, and config locally. This tool syncs them to a private GitHub repo so you never lose them. Default include lists per tool: | Tool | Source directory | Files backed up | |---|---|---| | Claude Code | ~/.claude | CLAUDE.md , settings.json , config.json , projects/ /memory/ , agents/ , commands/ , hooks/ , skills/ | | OpenAI Codex | ~/.codex | AGENTS.md , AGENTS.override.md , config.toml , .config.toml , memories/ | | Gemini CLI | ~/.gemini | GEMINI.md , settings.json , commands/ , extensions/ | | Cursor | ~/.cursor | rules/ .mdc files , mcp.json , permissions.json | Setup auto-detects which tools are installed and enables them. All include lists are fully configurable. - macOS for notifications and scheduled sync via LaunchAgent GitHub CLI https://cli.github.com/ brew install gh , authenticated git , python3 , rsync pre-installed on macOS git clone https://github.com/DiegoSalazar/AiSyncing.git ~/AiSyncing cd ~/AiSyncing bash setup.sh Setup will walk you through: Backup repo : picks a name, auto-creates a private GitHub repo via gh Git identity : name and email for backup commits defaults to your global git config AI tools : auto-detects installed tools by checking for their config directories Schedule : which hour to run the daily sync default: 3 PM Build and install : compiles the notification helper, installs the LaunchAgent, pushes the initial backup The AiSyncing template repo is saved as the upstream remote so you can pull updates later. bash ~/AiSyncing/sync.sh - For each enabled source, sync.sh reads the include list from config.json - Generates rsync filter rules at runtime auto-includes parent directories for nested patterns - Rsyncs each source directory into data/<source / - Commits with a message showing which sources changed: sync claude,gemini : 2026-08-24 15:00:00 - Pushes to your private backup repo - Sends a macOS notification click to open commit history Sources with missing directories are skipped with a warning, not fatal. If no sources sync, you get a notification about it. Everything is in config.json created by setup.sh . See config.example.json for the full schema. Each source has an include array of glob patterns. Edit it to add or remove files: { "sources": { "claude": { "enabled": true, "source dir": "~/.claude", "include": "CLAUDE.md", "projects/ /memory/ ", "agents/ ", "my-custom-dir/ " } } } Patterns follow rsync include syntax. Parent directories are auto-included for nested paths. Anything not matched is excluded. Add a new entry to sources with any name, its config directory, and the files you want backed up. For example, to add Windsurf Codeium : { "sources": { "windsurf": { "enabled": true, "source dir": "~/.codeium/windsurf", "include": ".windsurfrules", "memories/ ", "config.json", "settings.json", "prompts/ " } } } The sync script handles any number of sources. Each gets its own data/<name / subdirectory in the backup. Edit schedule hour in config.json , then re-run bash setup.sh to update the LaunchAgent. On macOS, each sync sends a banner notification showing the result. Click it to open your backup's commit history on GitHub. The notification helper is a minimal Swift app notifier.swift compiled into AiSyncing.app during setup. It runs as a background process no dock icon and uses macOS UserNotifications for proper banner support with click actions. On first notification, macOS will ask to allow notifications from "AI Syncing". Click Allow. Falls back to osascript if the app isn't built no click-to-open in fallback mode . Logs: ~/Library/Logs/ai-syncing.log Clone your backup repo on a new machine and copy the data back: git clone git@github.com:you/ai-backup.git ~/AiSyncing rsync -av ~/AiSyncing/data/claude/ ~/.claude/ rsync -av ~/AiSyncing/data/codex/ ~/.codex/ rsync -av ~/AiSyncing/data/gemini/ ~/.gemini/ rsync -av ~/AiSyncing/data/cursor/ ~/.cursor/ Re-enable scheduled sync: bash ~/AiSyncing/setup.sh bash ~/AiSyncing/uninstall.sh Stops the LaunchAgent and removes the compiled notification app. Your backup data and config are left in place. A weekly GitHub Action Research AI Tools monitors official documentation for all supported tools. It fetches doc pages from each tool's repo, hashes the content, and compares against stored baselines. If any docs change or become unreachable, it opens a GitHub issue for review. Can also be triggered manually from the Actions tab. Setup saves the AiSyncing template as the upstream remote: cd ~/AiSyncing git fetch upstream git merge upstream/main MIT
