Luckily I found Jestor right before the deal end. It is superbly useful with lots of features, an AIO for internal app building. I love the Superform with very powerful form building tools. The Gant and Smart Kanban apps are of the top useful - for me it is the first one that help me to build and customize a real Kanban app.

Also, it is extremely handly to have the built-in database for the apps. The no-code automations and integrations are there with some ready-made integrations (some very useful to Office, Google, Asana etc.). However, I wish there will be more integrations in the future.
