What Changed in Mirth Connect's Licensing Model?
For most of its history, Mirth Connect was free to download, deploy, and modify under the Mozilla Public License, which is why it became the default choice for cost-conscious healthcare integration teams for well over a decade. That changed with NextGen's 2026 announcement moving future versions to a commercial-only model, ending new open-source releases and reshaping what every existing deployment actually pays.
Versions Through 4.5.2 Remain Free and Open Source
The last open-source release, version 4.5.2, remains available under its original license and continues to function for existing deployments. It simply won't receive further security patches, bug fixes, or feature updates from NextGen going forward.
Version 4.6 and Later Require a Commercial License
Starting with 4.6, new releases are commercial-only, and the underlying source code is no longer publicly published on GitHub the way earlier versions were. Upgrading past 4.5.2 now means entering NextGen's licensing structure directly.
No Per-Interface or Per-Data-Source Charge
NextGen states directly that Mirth Connect licensing is not charged per interface or data source. Pricing is structured as a flat annual fee per server, which matches the flat-cost model the open-source version was known for.
Three Tiers: Enterprise, Gold, and Platinum
NextGen's current commercial structure offers three named tiers — Enterprise, Gold, and Platinum — each bundling a different set of extensions and support case allowances. Enterprise is positioned as the lower-cost entry point introduced alongside the 2026 change.
What Does Each License Tier Actually Cost?
NextGen doesn't publish a public price list for any of the three tiers, so the numbers below come from what third-party Mirth partners and support vendors have reported rather than an official rate card from NextGen itself. Treat anything not explicitly sourced as a starting point for your own quote, not a guarantee of what you'll actually be charged.
| Tier | What's Included | Reported Cost |
|---|---|---|
| Enterprise | Latest version access, SSL Manager, Channel History, Message Generator plugins | Not publicly disclosed |
| Gold | Enterprise features plus additional extensions and support cases | Not publicly disclosed |
| Platinum | Full extension set and highest support case allowance | Historically reported around $30,000/year by a NextGen integration partner |
| Research | Complimentary license for active non-profit research studies | Free, per NextGen's own published terms |
Enterprise and Gold Pricing Is Not Publicly Disclosed
Neither tier has a published rate on NextGen's own site, and third-party sources we reviewed didn't report a specific figure for either one. Any number you're quoted should be confirmed directly with NextGen or an authorized reseller.
Platinum Has Been Reported Around $30,000 Annually
One NextGen integration partner has publicly cited a historical Platinum price point near $30,000 per year, though this figure isn't from NextGen's own materials and may not reflect current pricing exactly.
The Research Tier Is Genuinely Free for Eligible Studies
NextGen offers a complimentary license specifically for active studies linked to non-profit research institutions, which is one of the few tier costs actually confirmed directly from NextGen's own published information.
Multi-Server and OEM Licensing Cost More Than a Single Tier Price Suggests
Running multiple production servers, or embedding Mirth Connect inside your own product under an OEM arrangement, adds cost beyond a single tier's base price, and neither is covered by the publicly reported figures above.
How to Actually Figure Out Your Real Cost
Since NextGen doesn't publish a rate card, getting an accurate number means combining what's publicly confirmed with a direct conversation with the vendor, rather than assuming any single reported figure applies to your specific deployment as-is.
Confirm Which Version You're Currently Running
Your actual cost path depends entirely on whether you're already on 4.5.2 or earlier, versus needing to move to 4.6 or later, since only the latter requires entering the new commercial licensing structure at all.
Request a Quote Specific to Your Server Count
Because pricing is per server rather than per interface, your real cost scales with how many production servers you run, not how many channels or message types are deployed on each one.
Ask Directly About OEM or Multi-Instance Terms
If you're embedding Mirth Connect in your own product or running several environments, ask specifically about OEM and multi-instance pricing, since the standard tier figures don't reflect either scenario accurately.
Compare the Total Against Third-Party Support Alternatives
Before committing to a commercial tier, compare the total annual cost against staying on the legacy open-source version with third-party support, which several vendors offer as a lower-total-cost alternative for existing deployments.
