PgBouncer vs Scalingo
A side-by-side editorial comparison of PgBouncer and Scalingo — release velocity, themes, recent moves, and the top alternatives to consider.
PgBouncer vs Scalingo: at a glance
What is PgBouncer?
PgBouncer patches a SCRAM flaw that let a known user log in as an admin
PgBouncer's 1.26 line pairs features with a heavy security load. 1.26.0 tracks search_path and default_transaction_read_only by default, so one client's SET no longer leaks to others in transaction pooling, adds pool_idle_timeout and per-user query_wait_timeout, and removes the old online-restart takeover in favour of rolling restarts. It also fixed three CVEs. Three weeks later, 1.26.1 fixed three more, including one where a user with a password in auth_file could log in as any other SCRAM user, admins included.
What is Scalingo?
Scalingo is back to routine runtime updates after its October router incident.
Scalingo is a European PaaS that keeps runtimes close to upstream. After a week of incident response that included router filters for Brotli and multipart requests, November 3 brought new base images for every stack, scalingo-22 through scalingo-26, patching a Brotli decoder CVE. The rest of the changelog is routine buildpack currency: Node.js, two JDK rounds, Composer 2.11, Python defaults and nginx 1.31.8 mainline. Python 3.11 is now deprecated.

PgBouncer patches a SCRAM flaw that let a known user log in as an admin
◆ Current state
PgBouncer's 1.26 line pairs features with a heavy security load. 1.26.0 tracks search_path and default_transaction_read_only by default, so one client's SET no longer leaks to others in transaction pooling, adds pool_idle_timeout and per-user query_wait_timeout, and removes the old online-restart takeover in favour of rolling restarts. It also fixed three CVEs. Three weeks later, 1.26.1 fixed three more, including one where a user with a password in auth_file could log in as any other SCRAM user, admins included.
◆ Where it's heading
Since 1.25.1 every release has carried CVE fixes in the authentication and packet-handling paths, and 1.26.1 found a second instance of a bug class fixed weeks earlier. The project is auditing its pre-auth surface in public, while 1.26.0 shows it still cleaning up long-standing pooling surprises.
◆ Prediction
More security point releases are likely while the auth and buffer code is under review; the entries give no sign of the next feature release.
Scalingo
5.0DEVOPS
Scalingo is back to routine runtime updates after its October router incident.
◆ Current state
Scalingo is a European PaaS that keeps runtimes close to upstream. After a week of incident response that included router filters for Brotli and multipart requests, November 3 brought new base images for every stack, scalingo-22 through scalingo-26, patching a Brotli decoder CVE. The rest of the changelog is routine buildpack currency: Node.js, two JDK rounds, Composer 2.11, Python defaults and nginx 1.31.8 mainline. Python 3.11 is now deprecated.
◆ Where it's heading
The changelog has returned to its normal rhythm of runtime currency. The Python 3.11 deprecation is the one item that will require customer action.
◆ Prediction
Expect more buildpack updates weekly and, at some point, a removal date for Python 3.11; whether the Brotli block on existing Node.js apps is lifted is unclear.
