Prowler vs Retool: at a glance
What is Prowler?
Prowler 5.47 collapses cloud onboarding to one step and explains why each issue matters.
Prowler ships a minor release every one to two weeks. 5.47.0 reworks the add-provider wizard into one connect step for every provider, with Lighthouse AI able to connect the provider itself after confirming details. The Issues page from 5.46 is renamed Exploitability issues and now leads with a verdict, an attack path and a Why column of five evidence legs. New Azure checks arrive, and an AWS security-group flaw where split CIDRs passed exposure checks is fixed.
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.

Prowler 5.47 collapses cloud onboarding to one step and explains why each issue matters.
◆ Current state
Prowler ships a minor release every one to two weeks. 5.47.0 reworks the add-provider wizard into one connect step for every provider, with Lighthouse AI able to connect the provider itself after confirming details. The Issues page from 5.46 is renamed Exploitability issues and now leads with a verdict, an attack path and a Why column of five evidence legs. New Azure checks arrive, and an AWS security-group flaw where split CIDRs passed exposure checks is fixed.
◆ Where it's heading
Prowler Cloud is moving from listing findings toward arguing which ones are exploitable, with the free engine as the data source. Lighthouse AI is also moving from advice to action, now connecting accounts as well as triaging findings, while MCP tools declare which calls are destructive. Coverage keeps growing through community-contributed checks.
◆ Prediction
Expect further Exploitability issues work built on the attack-path graph and more Lighthouse AI actions with confirmation steps.
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.
