Developer-First Communication APIs.

If you're building a software product, you don't want another dashboard. You want a clean REST API for your language, and documentation that respects your time. Fortis is built for developers first.

The Problem

Bolted-On Communication Is Fragile, Expensive, and Someone Else's Dashboard.

Most SaaS products that need messaging, voice, or OTP end up stitching together three vendors: one for SMS, one for voice, one for verification. Each has a different API style, a different billing model, and a different dashboard. When something breaks in production at 2am, you're debugging across three vendor support tickets.

Five places revenue leaks every day —

  1. Multiple messaging vendors, each with different API conventions

  2. No unified for all communication needs

  3. No way to test before going live without burning real credits

  4. Inconsistent webhook formats across channels

  5. Billing surprises from hidden per-feature charges

How Fortis helps

Unified API for Everything

One authentication. One. One webhook format. Send SMS, make voice calls, deliver OTPs, verify numbers — all via the same REST API. One vendor. One invoice. One support contact.

That Work

Official for Node.js, Python, PHP, Ruby, and Go. All open-source on GitHub. All maintained by the Fortis engineering team. No wrapper libraries from random contributors.

€5 Free Test Credit

Every new account gets €5 on signup to test SMS and WhatsApp messaging on real devices — enough to validate your integration end-to-end before you commit. No mocked environment that drifts from production: you're calling the same API and hitting the same delivery network — we just cover the first messages.

Transparent Pricing

Usage-based billing per message, per call, per lookup. Published rate card on the pricing page. In-app rate preview before every campaign launch. No setup fees, no monthly minimums, no surprise charges.
