Why we're better
Honest comparisons.
These pages are written by the engineering team, not marketing. Where a competitor is better, we say so. Where they're not, we say why — with code, line counts, and the actual API surface, not with adjectives.
Rules we hold ourselves to: no straw men. No screenshot from 2019. No "we're faster" without the benchmark.
If you find a claim on these pages that doesn't hold up, mail devs@bird.com and we'll fix it.
Pick the comparison that matches your stack.
Each page follows the same structure: what the other vendor is great at, where Bird is different, a matrix table, side-by-side code, and an honest switching-cost estimate.
vs Twilio
Twilio is the incumbent. They invented this category, the API surface is enormous, and the community is real. The honest read: Bird wins on register and on multi-channel parity; Twilio wins on scope and customer mass. Both are true.
vs Resend
Resend is the email API we admire most. Their React Email integration, their dashboard polish, their voice — all sharp. If you only ship email and don't see SMS or voice on your roadmap, Resend is great. If you ship more than email, or expect to, Bird is the better long-term bet.
vs Prelude
Prelude is hyper-specialized verify routing, with ML-based fraud detection at create time. If verify is your whole need, Prelude is sharp. If you'll also send transactional email or account notifications by SMS, Bird is the same API for all of it.
vs SendGrid
SendGrid was the email-API default a decade ago. The developer experience hasn't materially improved since. For new builds, Bird wins on register, multi-channel, OSS libraries, and dashboard. The honest reason teams stay on SendGrid today is brand inertia for procurement and existing IP reputation.
Numbers above were reported to us by each customer or surfaced from bird.com today. Full named-quote attribution is being confirmed customer-by-customer ahead of launch; the three pages that exist now (Airwallex, Bazaar, Glovo) have signed-off attribution on them.

We'll add comparison pages for these as customers ask for them. If you're evaluating Bird against a vendor we haven't written about, mail devs@bird.com — we'll write the comparison alongside your evaluation, and you can hold us to the same honesty rule as the four above.
