About Grantiva: built by
a developer, for developers.
Grantiva started from a simple frustration: iOS developers deserve better infrastructure that just works. Not five SDKs. Not enterprise sales calls. One tool that does everything after you write the code.
The origin story
I was building an iOS app that needed device attestation, feature flags, in-app feedback, and visual testing. The security side alone required server-side CBOR decoding, challenge management, and key attestation verification. The rest meant integrating LaunchDarkly, Instabug, and Percy.
Five vendors. Five SDKs. Five dashboards. Five bills. Each tool solved one problem well but created integration overhead, inconsistent APIs, and a monthly bill that made no sense for a team of one.
I wanted a single tool that understood iOS. Something where import Grantiva gave me attestation, risk scores, flags, feedback, support tickets, visual testing, and analytics. I wanted it to take three lines of Swift, not three sprints.
So I built it -- with Swift on both ends, Claude Code as my pair programmer, and the conviction that iOS developers deserve infrastructure that respects their time and their budgets.
Mission
Give iOS developers one tool instead of five
Every iOS app needs the same post-development infrastructure: device trust, feature management, user feedback, visual QA, and analytics. Today that means five vendors, five integrations, five bills. Grantiva collapses all of that into a single SDK with transparent pricing and a free tier that actually works.
Principles
What we believe
Transparent pricing
Flat monthly plans. No per-attestation fees. No overages. No surprise invoices. The price you see is the price you pay.
Developer experience first
Three lines of Swift to integrate. If it takes longer, we failed. The best platform is the one that ships.
One SDK simplicity
Nine capabilities from a single import. No dependency hell, no version conflicts, no integration overhead.
Privacy by default
Minimum data collection. Device IDs are ephemeral. IP addresses are anonymized after geolocation. We never sell data.
Technology
Built with boring, reliable technology
No bleeding-edge experiments. Every technology choice is proven at scale and chosen for reliability, developer experience, and operational simplicity.
Swift + Vapor
Same language on client and server. Type safety end-to-end. Swift 6 concurrency.
PostgreSQL
Battle-tested relational storage with Fluent ORM and 9 optimized indexes.
Redis
In-memory caching for MAD counts, sessions, rate limits, and real-time SSE.
Apple App Attest
Hardware-backed device verification built into every iPhone.
Railway
Reliable hosting with per-second billing and zero DevOps overhead.
React + Vite
Fast, modern frontend with TanStack Router, TanStack Query, and Tailwind CSS.
Claude Code
AI-assisted development from day one. Every line of backend and frontend code.
Stripe
Subscription management with lookup keys. Transparent pricing, no surprises.
