Gloo Gateway vs Robusta: at a glance
What is Gloo Gateway?
Gloo Gateway 1.20.29 stops a failed restart from wiping every Envoy's config
Gloo Gateway keeps maintaining 1.19, 1.20 and 1.21 in parallel. The 1.20.29 release fixes a failure where, after a gloo restart, a failed first reconcile sent every connected Envoy an empty config; it also keeps the in-memory Proxy store across setup re-runs and delays setup restarts until the first xDS sync. The 21 October batch had fixed proxies stuck on stale endpoints.
What is Robusta?
Robusta's 0.54.0 alpha returns to features: Prometheus tenants by namespace and Holmes fixes.
After a month of image patching and CI changes, Robusta's 0.54.0-alpha.1 carries product work again. It derives the Prometheus tenant from a namespace label in the UI and alert graphs, adds dnsConfig to the forwarder Helm deployment, stops the Holmes Slack bot check from blocking or dropping Slack messages, and retires the grafana-renderer. It also patches another set of Python dependency CVEs and stops self-hosted stores from fetching a Supabase key from SaaS.

Gloo Gateway 1.20.29 stops a failed restart from wiping every Envoy's config
◆ Current state
Gloo Gateway keeps maintaining 1.19, 1.20 and 1.21 in parallel. The 1.20.29 release fixes a failure where, after a gloo restart, a failed first reconcile sent every connected Envoy an empty config; it also keeps the in-memory Proxy store across setup re-runs and delays setup restarts until the first xDS sync. The 21 October batch had fixed proxies stuck on stale endpoints.
◆ Where it's heading
Recent work concentrates on control-plane failure modes: what Envoy receives when gloo restarts, reconciles badly or sends mismatched endpoint data. Each fix is backported across the supported lines alongside routine Go and dependency bumps.
◆ Prediction
The 1.21 and 1.19 backports of the empty-snapshot fix are the likely next entries, following the same-day batch pattern.
Robusta
5.0INFRA · APIS
Robusta's 0.54.0 alpha returns to features: Prometheus tenants by namespace and Holmes fixes.
◆ Current state
After a month of image patching and CI changes, Robusta's 0.54.0-alpha.1 carries product work again. It derives the Prometheus tenant from a namespace label in the UI and alert graphs, adds dnsConfig to the forwarder Helm deployment, stops the Holmes Slack bot check from blocking or dropping Slack messages, and retires the grafana-renderer. It also patches another set of Python dependency CVEs and stops self-hosted stores from fetching a Supabase key from SaaS.
◆ Where it's heading
The release mixes multi-tenant Prometheus support, Holmes AI assistant reliability and fewer SaaS dependencies for self-hosted installs. CVE patching remains a constant in every tag.
◆ Prediction
Further Holmes integration work and multi-tenant monitoring changes are the likeliest next items, alongside the usual CVE bumps.
