Yarify provides outsourced software development services for companies that would otherwise hire developers. Four ways to work with us: a fixed-price MVP or fixed-scope build, a dedicated team of 2–4 senior engineers, staff augmentation inside your team, and rescue of a stalled codebase. Fixed-scope and rescue projects carry our guarantee: our estimation overruns are our cost. Team engagements bill monthly with 2 weeks’ notice. You own all code and IP.
What we build, and how we work
Four engagement models, one free audit, and the software we build most often.
-
MVP development
Fixed-price MVP development. A senior team scopes it in writing, ships a deployed build early, demos weekly and launches a focused MVP in typically 8–12 weeks.
-
Dedicated development team
A dedicated development team of 2–4 senior engineers working on your product. Monthly billing, cancel with 2 weeks’ notice, 100% of code and IP is yours.
-
Staff augmentation
Senior engineers embedded in your existing team: your repo, your standups, your tracker. Monthly billing, 2 weeks’ notice, and every line of code is yours.
-
Software rescue
Stalled at 80%? Vendor vanished? AI-generated code nobody understands? We audit it for free, tell you to salvage, refactor or rebuild, then fix it for a fixed price.
-
Free code audit
A free, no-obligation codebase audit by a senior engineer. You get a written report: what is healthy, what is risky, and whether to keep, refactor or rebuild.
-
Custom software development
Internal tools, client portals, CRM and ERP integrations, and workflow automation. Built by senior engineers on a fixed written quote, owned by you.
-
AI development
Production AI, not demos. LLM integration, RAG, document processing and AI features built with evaluations, human review and GDPR-aware data handling.
-
SaaS development
SaaS products built on solid foundations: multi-tenancy, Stripe subscriptions, auth and roles, admin dashboards and product analytics. Fixed quote for the first version.
-
Web app development
Fast, SEO-ready web applications in Next.js and React: customer-facing apps, sales platforms and portals, with performance and search built into the architecture.
-
Mobile app development
iOS and Android apps from one React Native or Flutter codebase. A senior team takes it from scope to App Store review, at a fixed price or as a monthly team.
-
DevOps services
CI/CD, Docker, Kubernetes, Terraform and monitoring on AWS or GCP. Senior engineers make deploys boring, outages visible and the cloud bill smaller.
-
Cloud migration
Move from on-prem servers, a VPS or a legacy platform to AWS or Google Cloud. Containerised, defined in Terraform, rehearsed, and cut over with a rollback plan.

How every engagement starts
-
Free call
30 minutes with the engineer who would build it.
-
Written scope
What gets built, what does not, and how we will know it works.
-
Fixed quote or team plan
One price for a project, or a monthly plan for a team.
-
Kickoff
Your repo, your accounts, a staging URL early.
Fixed price. We eat the overruns.
On MVP, fixed-scope and rescue projects, the quoted price for the agreed written scope is the price you pay. If our estimate was wrong, the extra hours are our cost. Team engagements bill monthly with 2 weeks’ notice.
Start with a free code auditA senior team, on purpose
Our founder and a core of senior engineers. No juniors learning on your budget, no account managers. You talk to the person who writes the code.
If you need fifty engineers next month, we will say so on the first call. Everyone else gets the people who built Astrooly and our content automation platform.
Questions buyers ask us
Which software development service do I need?
A defined product to launch: a fixed-price MVP. A live product and an ongoing roadmap: a dedicated team. A tech lead who needs senior hands: staff augmentation. A stuck project: a free code audit, then a rescue. The free call sorts this out in 30 minutes.
Do you publish prices?
No. You get a fixed written quote or a monthly team plan after a free scoping call. Our cost guides show market ranges and the factors that drive price, so you can sanity-check any quote, including ours.
What does “we eat the overruns” cover?
MVP, fixed-scope and rescue projects. The quoted price for the agreed written scope is what you pay. If our estimate was wrong, the extra hours are our cost. Changes you request are quoted separately first. It does not apply to monthly team engagements.
Who owns the code?
You do, 100%, from day one, on every engagement model. We work in your repository and deploy to your cloud accounts, so there is nothing to transfer and nothing held back.
How big is your team?
Small and senior: our founder plus a core of senior engineers. Dedicated teams are usually 2–4 engineers. If you need a large team quickly, we will tell you on the first call that we are not the right vendor.
Do you work with companies outside the Czech Republic?
Yes. We are a Czech company based in Prague and work with clients internationally. We work CET hours, overlapping with EU business hours and US East Coast mornings, and contract under EU law.
No 40-page proposals. A fixed price and a start date.
