LibreSpeed vs Prowler
A side-by-side editorial comparison of LibreSpeed and Prowler — release velocity, themes, recent moves, and the top alternatives to consider.
LibreSpeed vs Prowler: at a glance
What is LibreSpeed?
After a two-year redesign, LibreSpeed is adding tests instead of polishing pixels.
LibreSpeed is a self-hosted speed test that spent roughly two years landing a new frontend design, shipped it behind a feature switch, then promoted it to default in 6.0.0. With that out of the way, 6.2.0 turns to capability: a standalone connection-stability test with live latency charting, packet-loss tracking, alerts and CSV export, plus PWA metadata so the tool can be installed from a browser. Docker deployment has been reworked in parallel, including a port change and PHP limits that were silently rejecting default upload chunks.
What is Prowler?
Prowler is turning its scanner into an agent that acts — and putting it behind the subscription.
Prowler still ships an open-source multi-cloud security scanner, but the last six releases have been about Lighthouse AI, its in-product agent, and the MCP server that feeds it. Lighthouse went from read-only Q&A to executing scans and managing providers, and now carries page context and reaches every tool family the MCP server advertises. Alongside that, 5.34.0 redrew the product line: CLI, Local Server, Local Dashboard and Hub stay free, while Cloud, Private Cloud and Lighthouse carry a subscription note on nearly every new feature.

LibreSpeed

After a two-year redesign, LibreSpeed is adding tests instead of polishing pixels.
◆ Current state
LibreSpeed is a self-hosted speed test that spent roughly two years landing a new frontend design, shipped it behind a feature switch, then promoted it to default in 6.0.0. With that out of the way, 6.2.0 turns to capability: a standalone connection-stability test with live latency charting, packet-loss tracking, alerts and CSV export, plus PWA metadata so the tool can be installed from a browser. Docker deployment has been reworked in parallel, including a port change and PHP limits that were silently rejecting default upload chunks.
◆ Where it's heading
The redesign was the blocker; now that it is default, releases are moving outward — a second measurement mode, installability, better multi-server list handling. The Docker thread runs alongside and is where the breaking changes live: default port moved from 80 to 8080 in preparation for rootless operation, post_max_size raised to accept the tool's own 20 MiB chunks, Alpine base updated. Much of the recent throughput comes from outside contributors and automated agents rather than a single maintainer.
◆ Prediction
Expect the stability test to gain the configuration and server-side plumbing the main speed test already has, and the rootless-container work that the port change was preparation for to land next. Nothing in the entries suggests a change to the project's self-hosted, no-backend-dependency positioning.
Prowler
7.5INFRA · APIS
Prowler is turning its scanner into an agent that acts — and putting it behind the subscription.
◆ Current state
Prowler still ships an open-source multi-cloud security scanner, but the last six releases have been about Lighthouse AI, its in-product agent, and the MCP server that feeds it. Lighthouse went from read-only Q&A to executing scans and managing providers, and now carries page context and reaches every tool family the MCP server advertises. Alongside that, 5.34.0 redrew the product line: CLI, Local Server, Local Dashboard and Hub stay free, while Cloud, Private Cloud and Lighthouse carry a subscription note on nearly every new feature.
◆ Where it's heading
The direction is a control plane, not a scanner. Prowler MCP is becoming the real API surface — integrations, users and roles are now agent-manageable on both Cloud and the self-hosted server, with RBAC as the only guardrail. Enterprise consolidation plumbing is arriving at the same cadence as the AI work: multi-domain SAML, Compliance Watchlist and Cross-Provider Compliance all target the org juggling many tenants and frameworks. The patch releases in between are dominated by container CVE reduction and correctness fixes in M365 and Attack Paths.
◆ Prediction
The admin surfaces not yet wired to MCP are the obvious next additions — compliance framework selection and the watchlist itself, given every other section of the app has been connected in sequence over the last four releases.
