What is Flagsmith?

Feature flag platform meets developers where they already work — Backstage, GitHub, Sentry — while adding governance for larger teams.

Flagsmith is a feature-flag and remote-config platform shipping monthly-ish improvements that fall into two clear arcs: bringing flag visibility into developer portals and CI surfaces (Backstage plugin, GitHub code references, Sentry tracking) and adding governance for larger teams (change requests for segments, granular permission inspection, multi-tenant segmentation).

What is Prowler?

Prowler 5.48 stops waiting for the next scan: it watches AWS live and can fix what breaks.

Prowler ships a minor release every one to two weeks. 5.48.0 adds Prowler Realtime for AWS in Prowler Cloud: it reads CloudTrail events as they happen, runs a targeted check on the touched resource and then alerts, opens a Terraform pull request or fixes the resource directly, depending on each account's policy. 5.47 had reduced provider setup to one step and made Issues lead with a verdict and an attack path.

Feature flag platform meets developers where they already work — Backstage, GitHub, Sentry — while adding governance for larger teams.

◆ Current state

Flagsmith is a feature-flag and remote-config platform shipping monthly-ish improvements that fall into two clear arcs: bringing flag visibility into developer portals and CI surfaces (Backstage plugin, GitHub code references, Sentry tracking) and adding governance for larger teams (change requests for segments, granular permission inspection, multi-tenant segmentation).

◆ Where it's heading

The arc is becoming a quieter primitive in larger engineering organizations — show flags inside Backstage, surface code references inside the dashboard, link feature releases to Sentry observability — alongside the change-control tooling those organizations require. Each release ladders into one of those two themes; the team is not chasing a category-redefining capability.

◆ Prediction

Expect more developer-portal and observability integrations (Datadog, Honeycomb, internal IDE plugins) and continued governance depth — likely audit-log filtering and SCIM/SSO additions. AI-assisted flag management is a plausible next direction given sector momentum but is not visible in the entries.

Prowler 5.48 stops waiting for the next scan: it watches AWS live and can fix what breaks.

◆ Current state

Prowler ships a minor release every one to two weeks. 5.48.0 adds Prowler Realtime for AWS in Prowler Cloud: it reads CloudTrail events as they happen, runs a targeted check on the touched resource and then alerts, opens a Terraform pull request or fixes the resource directly, depending on each account's policy. 5.47 had reduced provider setup to one step and made Issues lead with a verdict and an attack path.

◆ Where it's heading

Prowler is moving from a periodic scanner toward a response system: partial re-scans in 5.44, exploitability verdicts in 5.46-5.47, and now event-driven detection with reversible auto-remediation. The paid cloud tier carries most of this, with the open scanner feeding it.

◆ Prediction

Expect Realtime to extend to Azure or GCP event feeds and more checks to gain automatic fixes.
