From Proprietary Lock-In to Full Ownership in 6 Weeks

Client

A global workforce solutions enterprise running 400+ business applications on third-party low-code/no-code platforms.

Challenge

Active-user licensing costs across a 400-app portfolio scaled directly with business growth
Years on proprietary platforms created deep vendor lock-in, leaving no negotiating leverage or low-risk exit path
Scarce LC/NC platform talent drove higher operating costs and slower change velocity

Solution

Used an AI-first approach (powered by Indexnine SNAP™) to reverse-engineer application behavior into machine-readable, human-verifiable specifications
Rebuilt the application on self-hosted stack, then codified the approach into a repeatable blueprint
Used an AI-first approach to test pre- and post-rewrite codebases, proving full feature parity
Tech Stack: GCP, NextJS, PostgreSQL, Auth0, Cursor with codex & Sonnet4.5, SNAPTM Speckit

Impact

Delivered a production-ready migrated application in 6 weeks, giving leadership the confidence to greenlight a full portfolio transformation
Slashed platform operating costs by 70% by eliminating active-user licensing fees entirely
Enabled full customer ownership of the migrated application, ending vendor and scarce-skill dependency
A proven, repeatable modernization strategy for the entire enterprise portfolio

Strategic Significance

Demonstrates Indexnine’s ability to use an AI-first approach to reverse engineer from a no code proprietary platform with no loss of functionality in a massively accelerated factory approach.
