Production Meteor apps: maintenance, Meteor 3, and a road out.

Meteor app assessment

A structured audit of your app — versions, Atmosphere packages, Meteor 3 readiness, MongoDB and Node exposure, hosting posture — ending in a clear keep, upgrade, or migrate recommendation.

Meteor 3 migration

Fibers to async/await, package replacement, Node and MongoDB upgrades — converted in dependency order, behind tests, while you keep shipping.

Maintenance & feature delivery

Senior engineers who know pub/sub, methods, and Blaze work in your codebase — fixing what breaks and shipping what the roadmap needs.

Migration off Meteor

When leaving is the right end state: an incremental strangler migration to Next.js and React that preserves your MongoDB data layer, route by route, with a parallel-run cutover.

Meteor internals fluency

Pub/sub tuning, oplog tailing, method patterns, accounts internals — working knowledge that is genuinely rare in 2026.

Async migration experience

The Fibers-to-async conversion is a known, boundable problem to us: inventory first, mechanical diffs, linters carrying the load.

Unbiased keep-vs-leave counsel

We recommend keeping an app as readily as migrating off it. The evidence decides, not a rewrite agenda.

Tell us where it stands. We will give you a straight read on keep, upgrade, or migrate — and a plan for whichever it is.
