Why Choose an Affordable FastAPI Development Vendor
IRPR delivers production APIs faster and cheaper than most agencies.
We have shipped over 200 products in 50+ countries. Our average delivery time is 12 weeks, and 98% of projects launch on time. Every API gets a fixed price, not hourly billing.
Our senior engineers work with FastAPI daily. We use Pydantic for validation, SQLAlchemy for ORM, and async endpoints for maximum throughput. You get source code, CI/CD, and docs included.
How IRPR Compares to Other Vendors
Most agencies bill hourly and miss compliance. IRPR is different.
Generic dev shops often start without a fixed scope. They charge by the hour, delay timelines, and deliver undocumented code. You end up with hidden costs and no ownership.
IRPR locks the price and timeline after a 2-week Roadmap. We build FastAPI APIs with full documentation, CI/CD, and compliance from day one. You own everything.
- Hourly billing with no cap
- Unclear timeline, often delayed
- No compliance knowledge (HIPAA, PCI)
- Code ownership unclear
- No CI/CD or documentation
- No post-launch support
- Fixed price from $80K
- 8-12 week delivery guarantee
- HIPAA, PCI-DSS, SOC 2 expertise
- Full code ownership in your repo
- CI/CD pipeline and docs included
- 30-day post-launch support
Our FastAPI Development Process
We follow a 4-phase process to ship your API on time and on budget.
Every project starts with a discovery phase where we map your requirements. Then we build a detailed Roadmap with fixed price and timeline.
Our engineers code in 2-week sprints with daily standups. You see progress in real time. After testing and deployment, we hand over everything.
What Ships With Every FastAPI Project
Every deliverable includes more than just code. You get a production-ready system.
We don't just hand over a GitHub repo. Every project ships with infrastructure, monitoring, and documentation so your team can run it immediately.
From CI/CD pipelines to error tracking, we include everything needed for a smooth launch.
- Source code in your GitHub repository
- CI/CD pipeline with GitHub Actions
- Docker containers for local and production
- API documentation with Swagger/OpenAPI
- Unit tests with pytest (90%+ coverage)
- Sentry error tracking
- Logging with Datadog or CloudWatch
- Deployment to AWS, GCP, or Azure
- Post-launch support for 30 days
