Gloo Gateway vs Retool
A side-by-side editorial comparison of Gloo Gateway and Retool — release velocity, themes, recent moves, and the top alternatives to consider.
Gloo Gateway vs Retool: at a glance
What is Gloo Gateway?
Gloo Gateway's October batch fixes proxies that silently kept stale endpoints.
Gloo Gateway still maintains 1.19, 1.20 and 1.21 in parallel and releases them in same-day batches. The 2026-10-21 batch fixes a bug where a placeholder EDS assignment carried the wrong cluster name, so a proxy received an update it could not match, kept its old endpoints and never recovered. Each line also moved to Go 1.26.10; 1.21 additionally upgraded kin-openapi.
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.

Gloo Gateway

Gloo Gateway's October batch fixes proxies that silently kept stale endpoints.
◆ Current state
Gloo Gateway still maintains 1.19, 1.20 and 1.21 in parallel and releases them in same-day batches. The 2026-10-21 batch fixes a bug where a placeholder EDS assignment carried the wrong cluster name, so a proxy received an update it could not match, kept its old endpoints and never recovered. Each line also moved to Go 1.26.10; 1.21 additionally upgraded kin-openapi.
◆ Where it's heading
Releases remain maintenance: Go and Kubernetes bumps on a weekly rhythm, with an occasional real bug fix shipped to every line at once. The 1.18 line no longer appears in the October batches. No new features are visible.
◆ Prediction
Expect further same-day dependency batches across the three lines; the entries show no feature release coming.
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.
