What is Retool?

Retool is retiring standalone Assist while folding the same capability into the app builder.

Releases arrive several times a week and split into two lines. One extends the app-building agent — plan mode, managed agent context, multiple threads per branch — and the other builds out governance: access policies on PostgreSQL resources down to row level, BYOK AI token management, an admin onboarding hub. Against that, Assist is being removed outright on September 30, 2026.

What is Umbrel?

umbrelOS now pins any Docker container to the home screen — the app store stopped being the boundary.

umbrelOS 1.7 shipped in late April with home screen Shortcuts pointing at websites, custom ports and Docker containers, a text editor built into Files, advanced networking controls, folder sharing from external drives and seventeen new languages. The three patches since have been split between its own bugs — storage error screens, Tor connectivity — and inherited Linux kernel vulnerabilities, with emergency updates for CopyFail in early May and DirtyFrag a week later.

Retool is retiring standalone Assist while folding the same capability into the app builder.

◆ Current state

Releases arrive several times a week and split into two lines. One extends the app-building agent — plan mode, managed agent context, multiple threads per branch — and the other builds out governance: access policies on PostgreSQL resources down to row level, BYOK AI token management, an admin onboarding hub. Against that, Assist is being removed outright on September 30, 2026.

◆ Where it's heading

The agent is being consolidated into the app builder rather than offered as a separate assistant, and Assist's removal is the clearest statement of that. Alongside it, the controls an administrator needs before letting an agent touch production data are arriving in the same cadence — resource-level policies, token management, permission migrations. Retool is treating agent capability and agent governance as one shipping problem.

◆ Prediction

Access policies should extend past PostgreSQL to other resource types as they exit beta, and the app-building agent will likely gain review or approval steps of its own.

umbrelOS now pins any Docker container to the home screen — the app store stopped being the boundary.

◆ Current state

umbrelOS 1.7 shipped in late April with home screen Shortcuts pointing at websites, custom ports and Docker containers, a text editor built into Files, advanced networking controls, folder sharing from external drives and seventeen new languages. The three patches since have been split between its own bugs — storage error screens, Tor connectivity — and inherited Linux kernel vulnerabilities, with emergency updates for CopyFail in early May and DirtyFrag a week later.

◆ Where it's heading

Umbrel is building a desktop metaphor on top of a personal server: 1.5 added encrypted backups, file history and GPU acceleration, and 1.7 adds shortcuts, a text editor and network shares. At the same time, shipping a full operating system means inheriting the kernel's vulnerability schedule, and two of the four releases in this window exist solely because of it. That is the ongoing cost of the model.

◆ Prediction

Expect the Files and home screen surfaces to keep absorbing desktop functionality, since that is where the last two feature releases have concentrated. Also expect the kernel CVE cadence to keep interrupting it — the two May releases arrived a week apart and neither was planned.
