The official codemod handles 40% of changes. AI assistants fix files in isolation without migration context. You end up reading a 3-page guide and manually editing 200 files. MigrateBot understands the entire migration surface and applies every change with confidence scoring.
Watch a migration happen
// app/blog/[slug]/page.tsxexport default function BlogPost({ params }) {const { slug } = params;const session = cookies().get("token");const lang = headers().get("accept-language");return <Article slug={slug} />;}
Paste a GitHub URL or upload a zip. We detect the framework version automatically.
See every file that needs changes, grouped by category — async APIs, caching, config, tests, dependencies.
Deterministic transforms for config and deps. Claude for complex code changes. Every change gets a confidence score.
Get a zip with your migrated code, a full report, and a checklist of items flagged for manual review.
A purpose-built migration engine with hybrid AST + AI architecture.
AST-based detection to identify what needs to change. AI transformation only where deterministic rules aren't enough.
The #1 silent breakage in Next.js 15. Every fetch() call is flagged with explicit caching strategy recommendations.
No other tool touches your test files. Jest and Vitest mocks are updated for async API changes automatically.
Every change is rated high, medium, or low confidence. You decide what to trust and what to review manually.
Watch the migration happen file by file via server-sent events. No black box processing.
Migration report documenting every change, plus a manual review checklist for flagged items.
Pay per project or go unlimited. A manual migration costs 4-8 hours of engineering time.

Next.js 14 to 15 at launch. React, Tailwind, and more framework migrations are coming soon.
Your code is processed in ephemeral containers and deleted immediately after migration. We never store your source code.
Every change includes a confidence score. Low-confidence changes are flagged in a dedicated manual review report.
Yes — upload a zip file of your project. GitHub App integration for private repos is planned for v2.
Most projects under 200 files complete in 2-5 minutes.
