REALbasic Developers
für jede Arbeit ein

A REALbasic developer is a software engineer who builds cross-platform desktop applications using the REALbasic language and its modern successor, Xojo. These freelancers design, code, debug, and deploy native apps for macOS, Windows, and Linux from a single shared codebase. Hiring a skilled REALbasic developer is the fastest way to maintain legacy REALbasic projects or migrate them into the current Xojo IDE without rewriting your entire application.

What a REALbasic developer delivers

REALbasic, originally released by REAL Software, evolved into Xojo in 2013, and most experienced REALbasic programmers today work fluently across both. A freelance REALbasic developer produces compiled, native binaries that run on multiple operating systems while sharing the same business logic, user interface, and database layer. That cross-platform capability is the commercial reason clients still invest in this skill: one codebase, multiple deployment targets, and predictable maintenance costs.

Typical engagements range from small utilities and internal business tools to commercial shareware, scientific instruments, point-of-sale systems, and database-driven desktop clients. Many projects involve modernising older REALbasic 2005, 2006, or 2009 codebases that still run in production but need updates for current macOS or Windows releases.

How to evaluate REALbasic candidates

The right freelance REALbasic developer should show evidence of shipped, signed, cross-platform applications, not just code samples. Look for portfolio markers such as named applications on the Mac App Store or Microsoft Store, public Xojo forum activity, contributions to open-source Xojo projects, and experience with both API 1 and API 2 codebases. Strong candidates are comfortable reading legacy REALbasic code written by other developers and explaining migration trade-offs in plain language.

What are the steps to hiring a freelance REALbasic developer?

Hiring a REALbasic developer goes smoothly when your brief reflects the realities of cross-platform desktop work: target operating systems, IDE version, plugins in use, and the state of the existing codebase. The three steps below walk you through posting your project, reviewing bids, and awarding the work with confidence.

Step 1: Post your project on Freelancer.com

Your project post is the single biggest determinant of bid quality. A clear, specific brief filters out generic responses and attracts REALbasic developers whose experience genuinely matches your codebase and target platforms. Head to the post project page , where you fill in the brief, scope, timeline, and budget before publishing the project for freelancers to bid on.

Step 2: Review bids from freelancers

Bids are not just price quotes. They are short proposals that reveal how each freelancer interprets your brief, what approach they propose, and whether their timeline is realistic. Read the proposals carefully and shortlist candidates whose understanding of your REALbasic or Xojo work clearly matches what you described.

Step 3: Evaluate freelancers and award the project

The final decision combines proposal quality with hard profile evidence. For a REALbasic engagement, weigh consistency across multiple completed projects, not just a single impressive sample, since legacy desktop work rewards developers with a long track record of delivery.
