Stop Fighting Your
Legacy Code.
Modernize It.
Repave.ai transforms your old, tangled codebase into clean, modern code — so your team ships features in days, not weeks.
Legacy Code Is Slowing You Down
Your competitors move fast. But your team is stuck maintaining decades-old code that nobody fully understands.
Legacy systems create a vicious cycle: the harder they are to change, the more workarounds pile up, making them even harder to change.
- ✗Simple features take weeks to ship
- ✗Every change risks breaking something else
- ✗Top developers leave out of frustration
- ✗Technical debt compounds every sprint
We use AI to turn your legacy codebase into clean, modern code — while your developers sleep.
Repave.ai breaks massive modernization projects into small, safe units of work. Our AI orchestrator schedules, executes, and verifies each transformation automatically — so you wake up to cleaner code, every single day.
Define. Discover. Design. Develop. Decision.
You set the rules and make the final call — Repave handles the discovery, design, and development in between. Every stage is reviewable before the next begins.
Define
Set the guardrails up front — the validation rules every AI agent must follow, and your database policy for which schemas and stored procedures to retain versus modernize.
Discover
AI scans the codebase and builds a complete, source-traced inventory — requirements, features as legacy-grounded BDD, screens, APIs, data, batch jobs, and the as-is architecture.
Design
Design the modern target before implementing — the to-be architecture and tech stack, a design system, and a reusable application shell with interactive Figma prototypes.
Develop
Autonomous agents implement approved scenarios feature-by-feature on the modern stack, with tests, in isolation — bound by your rules and the agreed design.
Decision
You make the call: review completed features by replay, run UAT, triage bugs, then accept the work or send it back with feedback.
What You Get
Quality is speed. When your code is clean, everything gets faster.
10x Faster Delivery
Features that took weeks now take days. Clean code means your team spends time building, not deciphering.
Zero-Risk Migration
No big-bang rewrites. AI transforms your code incrementally with verified functional equivalence at every step.
Clean Architecture
Your modernized codebase follows industry best practices — modular, testable, and easy for any developer to understand.
Full Test Coverage
AI generates comprehensive tests during transformation, giving your team confidence to move fast without breaking things.
Slash Maintenance Costs
Stop paying a premium to maintain legacy systems. Modern code costs less to operate, change, and scale.
Attract Top Talent
Great engineers want to work with modern tech. A clean codebase helps you hire and retain the best people.
The Old Way Doesn't Work Anymore
Manual rewrites take years, cost millions, and often fail. AI changes everything.
Manual Rewrites Fail
Industry research shows that 70% of large-scale rewrite projects fail or go massively over budget. The all-or-nothing approach is too risky and too slow for today's pace of business.
AI Makes It Possible
For the first time, AI can understand entire codebases, apply modern patterns at scale, and verify every transformation — doing in weeks what used to take years.
