Scalingo vs WildFly
A side-by-side editorial comparison of Scalingo and WildFly — release velocity, themes, recent moves, and the top alternatives to consider.
Scalingo vs WildFly: at a glance
What is Scalingo?
Scalingo opens its Application Firewall to every app and adds CLI commands for it.
Scalingo is a European PaaS that keeps runtimes close to upstream. On November 9 its Application Firewall became available for all applications, letting any app restrict public HTTP and HTTPS access to allowed IPv4 ranges, and CLI 1.52.0 added commands to list, add and remove those rules plus an organizations command. Earlier in the month it patched every stack image for a Brotli decoder CVE and rebuilt nginx against zlib 1.4.
What is WildFly?
WildFly 42 brings virtual threads to Jakarta Concurrency.
WildFly is a Jakarta EE application server on a regular train of Beta, Final and patch releases. WildFly 42.0.0.Final (October 22) supports virtual threads in the Jakarta Concurrency 3.1 implementation, promotes idle time-based eviction for distributable sessions, SFSBs and timers to default stability, and adds automatic meter management for resources added at runtime. 41.0.1 in August was a security patch closing three IIOP CVEs.

5.0DEVOPS
Scalingo opens its Application Firewall to every app and adds CLI commands for it.
◆ Current state
Scalingo is a European PaaS that keeps runtimes close to upstream. On November 9 its Application Firewall became available for all applications, letting any app restrict public HTTP and HTTPS access to allowed IPv4 ranges, and CLI 1.52.0 added commands to list, add and remove those rules plus an organizations command. Earlier in the month it patched every stack image for a Brotli decoder CVE and rebuilt nginx against zlib 1.4.
◆ Where it's heading
After October's router incident, the platform is adding security controls at the edge alongside its routine runtime updates. Firewall rules in the CLI suggest they are meant to be scripted, not just set in the dashboard.
◆ Prediction
Expect the firewall to gain more options, IPv6 ranges being the obvious gap, alongside the usual buildpack updates.
WildFly
5.0DEVOPS
WildFly 42 brings virtual threads to Jakarta Concurrency.
◆ Current state
WildFly is a Jakarta EE application server on a regular train of Beta, Final and patch releases. WildFly 42.0.0.Final (October 22) supports virtual threads in the Jakarta Concurrency 3.1 implementation, promotes idle time-based eviction for distributable sessions, SFSBs and timers to default stability, and adds automatic meter management for resources added at runtime. 41.0.1 in August was a security patch closing three IIOP CVEs.
◆ Where it's heading
WildFly moves features through stability levels release by release; 42 promotes the eviction configuration that first arrived in 39. The bug list also shows continuing cleanup of XML parsing issues (CWE-611) and clustering edge cases.
◆ Prediction
Expect 42.0.1.Final next, consolidating fixes and component upgrades as 41.0.1 did.
