humble-bundle-keys

Pull every Steam key out of your Humble Bundle account into a single CSV.

humble-bundle-keys walks every page of your Humble Bundle Keys & Entitlements list, drives the Humble Choice membership pages on your behalf, captures every revealed key it finds, and writes them all into a single CSV you can sort, search, and bulk-paste into Steam.

It does NOT log into Steam. It stays inside humblebundle.com so the security model is simple.

Quick start

Requires Python 3.10+ and Chromium (auto-installed via Playwright).

# Install (using uv, recommended):
uv tool install humble-bundle-keys
playwright install chromium

# Or with pip:
pip install humble-bundle-keys
playwright install chromium

# First run — opens a browser window for login, then walks your library.
humble-bundle-keys

# Recommended first-time flow: read-only preview before anything mutates.
humble-bundle-keys --dry-run -v

# The full thing: extract everything, reveal pre-allocated keys, drive
# Humble Choice membership pages to claim subscription games.
humble-bundle-keys --browser-claim --max-claims 200 -v

After the run, your CSV is at ./humble-bundle-keys.csv and a full DEBUG-level log is at ~/.humble-bundle-keys/runs/run-<timestamp>.log.

What it does

1. Logs you in once in a real Chromium window (so 2FA works normally) and saves the session for reuse.
2. Walks every order in your library via Humble's private JSON API.
3. Reveals already-allocated keys by calling Humble's "Redeem" endpoint on each unrevealed entry.
4. Claims Humble Choice subscription games via API or browser-driven flows.
5. Writes everything to a CSV with one row per key.

What it doesn't do

• ❌ Log into Steam, GOG, Origin, or any other store
• ❌ Store your Humble password
• ❌ Make purchases or modify account settings
• ❌ Gift games to friends (gifts are irrevocable)

Three extraction modes

# Combined run: API reveal + browser claim, all in one go.
humble-bundle-keys --browser-claim --max-claims 200 --merge -v

Troubleshooting

See the Troubleshooting guide for common issues. The short version:

• Cloudflare 403s: Transient 403s are now auto-retried (up to 3 attempts with backoff). If you see persistent HTML errors, re-run normally.
• Selector breakage: Run humble-bundle-keys diagnose -v and attach safe-to-share.zip to an issue.
• Session expired: humble-bundle-keys logout && humble-bundle-keys
• Choice items detected: The summary now prints a copy-pasteable re-run command with the exact flags needed.
