Why choose a Python app development agency
Python delivers speed, readability, and a massive ecosystem. But building production-grade apps requires more than writing scripts.
Python is the second most popular language on GitHub. Its frameworks like Django and FastAPI let you build secure, scalable backends in weeks instead of months. But most teams underestimate the overhead of DevOps, security, and compliance. That is where a dedicated Python app development agency like IRPR delivers real value.
We handle the full lifecycle: architecture, coding, testing, CI/CD, cloud deployment, and 90-day post-launch support. Our fixed pricing model means you know the cost upfront. No hourly surprises. Over 200 products shipped across 50 countries.
Generic Python shop vs IRPR
Not all Python agencies deliver the same result. Here is how we compare.
Many Python shops work hourly, hand off code without documentation, and disappear after launch. That leaves you with technical debt, broken CI, and no one to call.
IRPR treats each project as a product. We write tests, set up automated deployment, and hand over full ownership of the code. Our average engagement lasts 12 weeks for an MVP, and we guarantee 99.9% uptime in production.

Fixed price, not hourly
Every Python app project gets a fixed quote after the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. Average MVP costs $80K-$250K.
Senior engineers only
Every engineer on your project has 8+ years of Python experience. No junior developers. We are a Python app development agency with a 98% on-time delivery rate.
Production-ready from sprint 2
From the second sprint, your app runs on a staging environment with CI/CD, automated tests, and error tracking. No waiting until the end to see working software.
Compliance built in
We have built HIPAA, PCI-DSS, SOC 2, and FERPA compliant apps for clients in healthcare, fintech, and edtech. Compliance is not an add-on - it is part of the architecture from day one.
Full code ownership
You own all source code, Docker files, CI/CD configs, and documentation. No lock-in, no licensing fees. We deploy to your AWS or GCP account.
Post-launch support included
Every project includes 90 days of monitoring, bug fixes, and hotfixes. We set up Sentry and PagerDuty so you can sleep while we watch the logs.
