License changes


Hope you like the latest release introducing Gauges. We also announce some licensing changes with Visifire 4.0.

Hundreds of Thousands of users have used Visifire at no charge for past 3 years. The growth in usage has been phenomenal & we think Visifire has helped many in their charting needs. Our investment in conceiving, and continuously advancing Visifire to where it is today has been substantial and we’re proud of the contribution that we are able to make to the community. Given the ever-increasing popularity, growing support costs, and the need for continuous product improvements, it is no longer feasible for us to offer Visifire at no charge. Version 4.0 onwards Visifire will no longer be free & open-source. This should also bring a great relief to all WP7 app developers who were finding it difficult to list their apps which use Visifire in Windows Marketplace due to Microsoft’s stance on GPLed apps. All previous versions of Visifire remain open-source & can be used at no charge as long as you conform to GPLv3. We’ll continue to support the previous versions till we find it feasible.

Download Visifire 4.0 Trial here. It contains all features of full version but with a tiny watermark saying that its a trial edition.

We know that this sudden change will cause pain for some people in the Visifire community, and we apologize for the change in policy. As always, your feedback is important to us. Feel free to add your thoughts in the comments section below.

    I totally understand to shift to a more commercial product. However you mention that previous version are still available, but it seems to not be the case. Am I missing something or this post is not up do date ? if so you should cut the part that say this, it is confusing.

    Yes, the previous versions are still available along with their source code. You can find them in hosted project on Google code –

    I think you should release a free version with a basic set of charts

    I’ve downloaded the GPU 3.6.8 version, but it still has a ‘Trial’ watermark. Why is this?

    To avoid multiple binaries we let the watermark stay on both Trial & Open Source Edition. There are no limitations what-so-ever with GPL version.

    I also completely see the need to start charging, and thanks for keeping the GPL version available! However, I also had a problem with the banner and I needed to remove the banner as it was covering some small plots I made. I posted instructions on how to do that here for anyone who wants to do the same:
