Incus vs Retool: at a glance
What is Incus?
Incus 7.6 fixes 18 security issues, eight critical, and adds SR-IOV NIC live migration
Incus 7.6, released October 30, carries 18 security fixes, eight rated critical, many of them about restricted projects reaching the default project or the host, plus an authentication bypass through unverified client certificate chains. Its features aim at larger environments: live migration for VMs using SR-IOV NICs, multifd for VM live migration, cluster healing options, compression for block volumes, and OIDC opaque tokens. 7.5 before it added live migration between projects, cluster metrics and NVIDIA GPU cliques. The 7.0 LTS branch received a second patch, 7.0.2, with no described changes.
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.

Incus 7.6 fixes 18 security issues, eight critical, and adds SR-IOV NIC live migration
◆ Current state
Incus 7.6, released October 30, carries 18 security fixes, eight rated critical, many of them about restricted projects reaching the default project or the host, plus an authentication bypass through unverified client certificate chains. Its features aim at larger environments: live migration for VMs using SR-IOV NICs, multifd for VM live migration, cluster healing options, compression for block volumes, and OIDC opaque tokens. 7.5 before it added live migration between projects, cluster metrics and NVIDIA GPU cliques. The 7.0 LTS branch received a second patch, 7.0.2, with no described changes.
◆ Where it's heading
Live migration is still the through-line: 7.4 made it near-live for dependent disks, 7.5 took it across projects, and 7.6 extends it to VMs using SR-IOV NICs. The other thread is multi-tenancy under scrutiny. The size of the 7.6 security batch, with several critical items in project isolation, shows that restricted projects are now being tested as a real boundary, and the release adds a build and threat model for Anthropic's OSS Scanner.
◆ Prediction
Expect a 7.6.x patch or further security fixes, because the project-isolation findings cover a wide surface. The monthly feature cadence should continue with more live-migration throughput work, given multifd and the throughput improvements in this release.
Retool
6.3INFRA · APIS
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.
