What is Lima?

Lima 2.3 nears release, with a Windows path that drops QEMU and a new TUI

Lima v2.3.0-rc.0 is out with an experimental HCS driver that removes the QEMU dependency on Windows hosts, block device attachment for VZ guests on macOS, and experimental shared, host and bridged networks on Linux hosts. limactl menu adds a menu-based interface, which now opens when limactl runs on a terminal without arguments. The default Ubuntu template moves to 26.10.

What is Retool?

Retool's app builder hits GA, generating React apps, with spend controls beside it.

Retool's app builder is generally available: it builds React apps from natural language, from MCP-compatible coding agents or from imported React code. On the same day Retool shipped limits on AI credit and token usage by user, group and model, along with credit packs by card on all paid plans. Private npm registries for Enterprise apps and GPT 6.1 Terra followed, while self-hosted stable channels took three more 4.34 updates.

Lima 2.3 nears release, with a Windows path that drops QEMU and a new TUI

◆ Current state

Lima v2.3.0-rc.0 is out with an experimental HCS driver that removes the QEMU dependency on Windows hosts, block device attachment for VZ guests on macOS, and experimental shared, host and bridged networks on Linux hosts. limactl menu adds a menu-based interface, which now opens when limactl runs on a terminal without arguments. The default Ubuntu template moves to 26.10.

◆ Where it's heading

The any-guest, any-host direction now reaches all three desktop platforms in one release, and each host gets a feature suited to its own virtualization stack. The menu interface is a different kind of addition: it aims at people who do not want to memorize the CLI. LFX mentees and outside contributors continue to carry much of this work, and the project's experimental-first labeling still applies to the biggest items.

◆ Prediction

A 2.3.0 final is the next step after rc.0. The HCS driver and Linux network modes should stay experimental there, following the pattern earlier platform additions took.

Retool's app builder hits GA, generating React apps, with spend controls beside it.

◆ Current state

Retool's app builder is generally available: it builds React apps from natural language, from MCP-compatible coding agents or from imported React code. On the same day Retool shipped limits on AI credit and token usage by user, group and model, along with credit packs by card on all paid plans. Private npm registries for Enterprise apps and GPT 6.1 Terra followed, while self-hosted stable channels took three more 4.34 updates.

◆ Where it's heading

Retool is turning AI app generation into a metered product line: the builder is the surface, and credits and spend limits are how it gets sold and governed. Private npm registries point the same way, since generated React apps need a company's own packages. Self-hosted customers stay on a separate steady cadence of Edge builds and stable patches.

◆ Prediction

Expect more Enterprise controls around app builder output and the next frontier model added soon after launch. The entries don't show how AI credits are priced.
