Show HN: Transmit.dev – A fair, credit-based alternative to CPaaS vendors

Share This Post

Hey HN — we built Transmit.dev because we were frustrated with how communication APIs keep hiking prices and forcing developers into tiers they don’t need.

When Mailgun doubled their prices overnight, that was the last straw — so we decided to launch today.

Transmit.dev is a developer-first communication API — starting with email today and expanding to SMS, voice, and chat next.

We were tired of paying $20, $50, $100+ per month for plans we didn’t fully use. If you’re in e-commerce or run seasonal workloads, you know the pain — those unspent credits you already paid for just expire. That shouldn’t happen.

Here’s how we fixed it:

$0.50 per 1,000 emails
Credits that last — no expiration BS
Real-time billing and usage tracking
Unified credit system across all channels

Stack:

Next.js 15 + Vercel (frontend)

Convex + PlanetScale (backend)

TypeScript everywhere

We wanted something simple, fair, and transparent — so we built it.

Would love feedback from the HN community, especially around developer experience, pricing clarity, and feature priorities (e.g. webhooks, logs, jobs, SMS).

Puches & the Transmit.dev team
