jBPM might be a bit more popular than Timy. We know about 1 link to it since March 2021 and only 1 link to Timy. We are tracking product recommendations and mentions on various public social media platforms and blogs. They can help you identify which product is more popular and what people think of it.
I've used the Timy (https://timy.website/) free tier for this in the past. The one feature that was missing though was to schedule messages to be sent at a certain time in the recipient's timezone. Unfortunately it looks like MessageThemLater doesn't support that feature either. - Source: Hacker News / almost 3 years ago
Https://jbpm.org, https://kogito.kie.org, and the other projects under the https://kie.org umbrella are also worth looking into. Jbpm is the grandfather of several of the Java based BPMN solutions if I'm not mistaken. Source: over 2 years ago
