Blue was really an excellent process and project management tool. Reliable, fast, generous limits, easy to use, great features. Most of all, the founder was always approachable and responsive.

In May 2026, Blue enforced a change to a new Version 2.0. Literally everything turned south from here. Limits were cut in ridiculous ways disabling any reasonable utilization. Everything implemented before became unusable over night. To get things back, the only option s entering a USD 500 subscription. The founder stopped responding in the usual attentive way and turned literally hostile.
It appears as if the AppSumo campaign was intentionally created to lure users to use the systems and to generate funds to develop Blue - only to kick everyone out that was helping to expand the capabilities of Blue financially and with useful feedback/ input. And AppSumo also got offended when the old unlimited features were still sold via the platform till the end. Which could be considered intentional cheating.

Total and utter disappointment.
Hope AppSumo will find a way out of this mess although they did nothing wrong at all.
