AppLedger honest check

Honest security feedback, in plain language, for apps people build with AI tools such as Claude Code, Codex, Cursor and Lovable.

AppLedger checks your app folder with independent scanners and explains what they find in everyday words: what is wrong, why it matters, and what to do. It also writes a fix request you can hand straight to the AI tool that built the app, then checks again.

What it checks

Each run produces, in <your-app>/.appledger/:

• report.html: a score, who may use the app right now (only you, your team, the whole company), and every problem in plain words
• fix-prompt.md: a ready-made fix request for your coding agent
• findings.json: the same findings for tools and dashboards

Two ways to run

What gets uploaded in hosted mode

• Sent: files Git would commit (git ls-files, including new files that aren't ignored). Outside a Git repository, .gitignore is still honoured.
• Never sent: .env and .env.* (except .env.example, .env.sample, .env.template), *.pem, *.key, *.p12, *.pfx, SSH keys, .npmrc, .pypirc, .netrc, *credentials*.json, service-account*.json, secrets.*, the folders cert, certs, secrets, .ssh and .aws, .claude/settings.local.json, Terraform state, password files, Ansible Vault files, Kubernetes/Helm secret manifests, certificates and similar (full list in src/appledger/uploadpolicy.py). The server drops such files again as a second safety net.
• Skipped: dependencies, build output, media, documents and data files (CSV, spreadsheets, slides, SQL, logs, data dumps) and files over 1 MB.

If a secret file is committed to Git or not ignored, the check reports it as a problem by file name. Its content is never read or sent.

See exactly what would be sent, and what is left out and why, without uploading anything:

python -m appledger path/to/your-app --list-files

The first hosted check of a folder asks you to confirm. In scripts and scheduled runs, pass --yes. If the code belongs to your employer or a client, make sure you're allowed to upload it, or use local mode.

Install

Claude Code plugin (recommended: adds the guided check-my-app skill):

claude plugin marketplace add contentasoftware/appledger
claude plugin install appledger@appledger

In the Claude Code desktop app, add the marketplace contentasoftware/appledger in the plugin settings instead. Start a new session, then ask: "Is my app safe to share?" or "Add this app to AppLedger".

MCP server only (needs uv):

claude mcp add appledger -- uvx --from appledger appledger-mcp

Command line:

pip install appledger
python -m appledger path/to/your-app

Step-by-step guide with troubleshooting: https://appledger.net/docs/

Version 0.2.0 (upload preview, consent, secret-file exclusion, scheduling) is being released to PyPI; until then pip install appledger gets 0.1.x.

Company dashboard

Create a free account at appledger.net to keep every app your people check in one ledger: owner, grade, score trend, who may use it and which AI tool built it. Create a connection key under "Connect a computer", then save it on each computer:

python -m appledger --connect al_your_key

Or tell Claude: "Connect AppLedger with this key: al_…". The key is saved in ~/.appledger/key; APPLEDGER_KEY overrides it and --disconnect removes it.

From then on each check also saves a summary to your dashboard: the app's name, score, grade, problem counts, the list of problems found (level and short title, up to 60; never code or file paths), and the scanners used. Never the code.

You can also add an app in the web app with Add app: register it without code, or upload a zip to check it in the browser (the zip is scanned and deleted the same way).

Scheduled checks

python -m appledger path/to/your-app --schedule weekly --yes   # or daily
python -m appledger --schedules                                 # list
python -m appledger path/to/your-app --schedule off             # stop

Uses Windows Task Scheduler on Windows and cron on macOS and Linux. Hosted scheduled checks need the one-time --yes consent; add --local to schedule local checks instead. --quiet prints one line per check.

Local mode setup

1. Trivy: winget install AquaSecurity.Trivy (Windows) or brew install trivy (Mac)
2. Opengrep: download from the releases page and put it on your PATH
3. Rules: git clone --depth 1 https://github.com/opengrep/opengrep-rules.git ~/.appledger/opengrep-rules
4. Check: python -m appledger --doctor
