Modernize the code you can't afford to rewrite
Syntic AI Engineers migrate frameworks, languages, and platforms at a pace humans can't match — preserving behavior, generating tests, and shipping reviewable PRs your team can trust.
- 10x
- faster migrations vs. hand-rolled refactors
- <3%
- of migrated files require human rework
- 1 PR
- per logical change — every diff is reviewable
Built for the migrations nobody wants to do
Reads the whole codebase
Cross-file dependency understanding so refactors don't break what they shouldn't touch.
Cross-language fluency
Java→Kotlin, Python 2→3, AngularJS→React, COBOL→Java — and many more.
Reviewable PRs
Small, themed PRs with rationale and tests, not one mega-diff humans can't review.
Behavior preservation
Auto-generated characterization tests verify legacy behavior survives the migration.
Plugs into your CI
Migrations run in your pipelines, in your runners, against your test matrix.
Stays inside your boundary
Self-hosted runner option for proprietary, regulated, or air-gapped code.
How teams put it to work
Framework upgrades
React 16→19, .NET Framework→.NET, Spring Boot 2→3, Django 2→5 — done in weeks, not quarters.
Language migrations
Move off COBOL, VB6, Perl, or AngularJS with characterization tests covering the original behavior.
Cloud re-platforming
Refactor monoliths into services, lift-and-shift to managed runtimes, swap data layers.
Dependency hygiene
Remove deprecated APIs and obsolete libraries across thousands of files in a single pass.
