Code Conversion &
Language Migration Services

Beehive rewrites software while preserving every feature, improving every pattern.

Who We Build For
  • Companies migrating from legacy languages (PHP, Perl, ColdFusion) to modern stacks
  • Teams unifying codebases after acquisitions or consolidating polyglot architectures
  • Startups rewriting prototypes or AI code from one framework to another for production readiness
  • Enterprises moving from JavaScript to TypeScript or from monolith frameworks to modern alternatives

Code conversion isn’t just translating syntax, it’s re-engineering software to take advantage of the target language’s strengths, idioms, and ecosystem.

Beehive Software rewrites codebases from one language or framework to another while preserving all business logic, improving code quality, and adding test coverage that didn’t exist before.

We handle full application rewrites, gradual migrations, and hybrid approaches that let teams transition incrementally without downtime.

An extraordinary collaboration with the AI-developing team at Beehive. Respectful, responsive, going out of their way to understand the specifics of our world in the design of the software. I would give them six stars.

Blue Zones engaged Beehive software initially to develop a mobile app based on Dan Buettner's book "The Blue Zones Challenge." What initially started as an isolated mobile app engagement quickly grew to more comprehensive scope of services supporting all consumer-facing technologies. Beehive's unique project decomposition and trusted developer network crowdsourcing has kept costs low, quality high, and most importantly timelines ahead of schedule. The speed of feature development has been tremendous, allowing us to respond to market conditions and new ideas very rapidly. Lastly, the service we get from Beehive is personal, supportive and strong. Every team member we interact with proves that they hold our interests very highly, and they push us to design and build better solutions than we could alone.

Working with Beehive Software was so much more than just hiring someone to build my vision it was a true partnership from start to finish. From the beginning,Yaron and his team made the experience feel collaborative, smooth, and genuinely enjoyable. They weren’t just coding a product; they were deeply invested in bringing my ideas to life in a way that felt aligned, intuitive, and strategic. The process was easy, flexible, and even fun. Every time I had a new request, change, or question, they were there on time, responsive, and ready to support. What stood out most was how confident they made me feel at every step. I always had the sense that Yaron and the team knew exactly what they were doing, and that level of competence gave me peace of mind through what could have been an overwhelming process. If you’re looking for a team that’s professional, experienced, collaborative, and genuinely cares about your success, I can’t recommend Beehive Software enough. They exceeded my expectation.
