Open Source Managed File Transfer Software

Current & Past Options [Updated January 2019]


If you are looking for an open source Managed File Transfer (MFT) solution, this blog is for you. It’s written by Pro2col Managing Director James Lewis, who is a self-confessed file transfer geek with over two decades’ experience working with file transfer technologies and vendors. He’s been following open source projects for many years and regularly updates this blog as new options become available.


I originally wrote this post back in July 2012, after a number of requests for open source MFT from potential customers. They’d found us via our website, which clearly promoted a wide variety of commercial products, with no reference to open source, however they were only interested in open source options.

Free clearly doesn’t pay the bills, but being a bit of an industry geek, I decided to do the research and find out what was available. I identified a couple of SourceForge projects, which I’ve been following over the years.

For the record, I’m a fan of open source. Our previous Technical Director was a thrifty Northerner, who converted me. We ran various elements of the business very successfully on open source projects. Our support ticketing system was based on OTRS and our monitoring system used Nagios. Both were mature applications, widely used in the open source community and provided considerable functionality at a price that suited!



When it comes to open source MFT though, the landscape is patchy at best. Open source FTP servers exist in abundance and can provide the landing point for incoming and outgoing files, but open source MFT projects appear to be scarce. I suspect that this is because MFT hasn’t been one of those technologies that every company deploys.

Recent changes in EU regulation in the form of GDPR, also impacts this space. GDPR legislation requires increased levels of security, audit trails and reporting on any transfers involving personal data. (See our blog posts Encryption at rest for GDPR and Where is your data going and why?)

Open source MFT trends

My research over the past 6-7 years has highlighted a few trends that don’t bode well for open source MFT projects, and may be a reflection of the wider open source landscape. In general, they have slotted into the following categories:

  • The company is acquired and the free option is removed. Some or all of the functionality is incorporated into a commercial offering.
  • The part-time developer gets a contract or new job and the project gets shelved.
  • The project is labeled as MFT, but doesn’t contain the key functions of all commercial offerings in the market.
  • Commercial vendors offer a pseudo open source product with limited functionality and encourage migration to their commercial solution.

Genuine open source projects

There are just two genuine projects that I’ve found so far. I couldn’t recommend either, as I’ve not invested any time personally or asked our technical consultants to review them, however they have ongoing development and support packages.

Yade – an open source project, previously going under the name of SOSFTP. This project has been around since at least 2012. SOS Berlin lists a number of customers on their website and provides support and consulting packages. Currently my favourite option, based upon the length of time they’ve been around.

WAARP – a relative newcomer to the market but it looks to have all the basics covered. It also provides commercial support options and their website provides visibility of who is involved in the project. This is certainly one to watch.

If you’re a user of either Yade or WAARP, I’d be interested in hearing from you. I’m keen to understand how complete the project is, how responsive the development team are and what your experience of their support offering has been like.

Free products from commercial vendors

As I’ve already mentioned, these tend to be products with limited functionality, which will ultimately encourage migration to a commercial solution.

Coviant Diplomat OpenPGP Community Edition – This is a free OpenPGP tool to automate PGP encryption and decryption.

Coviant Diplomat Cloud Storage Community Edition – A free tool to PGP-encrypt files being transferred to cloud storage sites.

HelpSystems Free FTP Server – this is a free edition of GoAnywhere MFT, with administrator dashboard, extensive security, audit reports and more.

FTP Voyager – A free GUI FTP client, FTPS client and SFTP client software for Windows. The main interface is similar to dozens of other FTP clients, but it also includes powerful scheduling utilities and synchronisation utilities for free.

Some open source MFT that is no more

These are some of the open source projects that I have been following, which are no longer available:

Policy Patrol by OPSWAT – has now become Metadefender Email Security. The Managed File Transfer element of the open source project appears to have been shut down.

ShieldShare by BlockMaster – now appears to be part of the DataLocker stable but their focus is on encrypted storage. It’s unclear whether the product was acquired for the encryption capabilities. Project shut down.

Appterra – their open source supply chain integration platform with Managed File Transfer capabilities was acquired by Descartes. The open source project has been shut down.

DivConq MFT – a SourceForge project that looked promising but the developers seem to have ended the project and the associated website has closed down.

Karonte – positioned as an open source Managed File Transfer solution but it doesn’t have the basic functionality we consider critical for MFT.

In conclusion

Whilst the open source marketplace can be a fantastic resource for some business applications, MFT isn’t currently one of them. If your business is in the tech space or you’ve got an extensive development and technical team, then open source MFT may be a viable option for you.

However, MFT is mission critical for almost all of our customers. Many come to us looking to mitigate the security and compliance risks associated with supporting a bespoke or homegrown solution. Unmanaged in-house scripts in particular are one of the biggest risks to an organisation’s GDPR compliance. Additionally, as developers and contractors move on, companies get stuck with a solution without documentation, no training and no one to make changes or fix faults.

If you’d like to discuss your MFT requirements and the impact of GDPR, I’d be pleased to talk them through with you. You may be surprised at how much bang you get for your buck these days in commercially available products. You can contact us via the web form, or call 0333 123 1240.
