EsperHA: High-Availability for Event Processing

EsperHA is now generally available under a commercial license. You can sign up for a free time limited trial license and get a unique chance to try the product features with out of the box samples and possibly even in your context. The evaluation include a free entitlement to EsperTech support system for the time of your evaluation.

How does it work? How much does it cost?

Please fill in the form below.
You will have to accept a trial evaluation license agreement in a click-wrap form, and will be granted access to a trial version of EsperHA with all documentation and samples. You will also be entitled access to EsperHA private community forums and EsperTech support system to conduct your evaluation with appropriate confidentiality.
You will also be entitled a license key for 30 days evaluation that you can renew upon demand.
This is provided at no cost, and we reserve the right to refuse to grant trial licenses if contact information such as email, role and company name are innacurate or incomplete. An EsperTech representative may also contact you to understand your objectives for this evaluation.

Will there be a public trial version for which I don't need to register?

We don't plan to provide trial license anonymously. Esper is already available under an open source license, and EsperHA is tailored for dependability and availability requirements typical of an enterprise use.
Take action today to leverage Esper with no compromise on high-availability with EsperHA.
