Verify comparisons

Honest comparisons.

These pages are written by the engineering team, not marketing. Where the other platform is the better pick, we say so, and each page names what it is great at before it names anything else.

Verification is a narrow product and the differences are concrete: which channels a passcode can arrive on, whether a retry can send a second code, how much a failed check tells you, and how much of the verification surface an AI agent can operate without you.

If you find a claim on these pages that doesn't hold up, mail devs@bird.com and we'll fix it.

Start with one channel.
Add the others when you're ready.

A test API key is yours immediately. Production unlocks when you add a payment method and verify a sender.

Using Claude Code, Cursor, or Codex? Copy a setup prompt and your agent installs the Bird CLI and skills for you. Pick yours:
