IronBarcode Roadmap

IronBarcode originated from our customer requests. Its origin story was a direct result of developers' pain points, with our team doing a deep dive into community forums and finding a repeated demand for a more effective solution.

We listened to our community and created a product to give them a better solution than the market was offering.

Today we continually drive IronBarcode’s performance by applying the latest technology to improve image filters, computer vision, and machine learning. IronBarcode is now used in 96 countries, and we’d like to see its application grow as it continues to improve.

More use cases will be covered to improve reading from live streams and barcode readers. Longer term, our plan is to launch IronBarcode for multiple programming languages.
