What is PgBouncer?
PgBouncer added LDAP and direct TLS, then spent two releases patching auth-path CVEs
PgBouncer's 1.25 line introduced LDAP authentication and client-side direct TLS connections, the faster handshake PostgreSQL 17 added. The two releases since have been security patches: an integer overflow in packet parsing and an unchecked strlcat return in the SCRAM code, both remotely crashable pre-auth, following a December fix for arbitrary SQL execution via a malicious search_path in the startup message.
What is Rivet?
Rivet 3.0 Preview runs as one stateless binary on WarpDrive, with S3 as its only dependency.
Rivet has spent two months building infrastructure for long-lived actors and AI agents: BYOC in customer clouds, OpenTelemetry tracing, actor-scoped JWTs, Pi agent runtimes and agentOS Hosted VMs. On October 5 it said 3.0 would replace NATS with S3. The October 26 3.0 Preview delivers that: a new storage engine, WarpDrive, promises bottomless storage on S3 at SSD speed, and Rivet becomes a single stateless binary.

PgBouncer added LDAP and direct TLS, then spent two releases patching auth-path CVEs
◆ Current state
PgBouncer's 1.25 line introduced LDAP authentication and client-side direct TLS connections, the faster handshake PostgreSQL 17 added. The two releases since have been security patches: an integer overflow in packet parsing and an unchecked strlcat return in the SCRAM code, both remotely crashable pre-auth, following a December fix for arbitrary SQL execution via a malicious search_path in the startup message.
◆ Where it's heading
The pattern is unmistakable — every recent vulnerability sits in the authentication path, which is exactly where PgBouncer has been adding surface. LDAP, SCRAM handling and startup-parameter tracking all expanded what the proxy parses before a client is trusted. The connection-limit and admin-console work in 1.24 suggests a parallel track aimed at multi-tenant operators.
◆ Prediction
Expect continued hardening of the pre-authentication parsing path, and eventually server-side direct TLS, which 1.25.0 explicitly noted PgBouncer cannot yet do.
Rivet
7.5DEVOPS
Rivet 3.0 Preview runs as one stateless binary on WarpDrive, with S3 as its only dependency.
◆ Current state
Rivet has spent two months building infrastructure for long-lived actors and AI agents: BYOC in customer clouds, OpenTelemetry tracing, actor-scoped JWTs, Pi agent runtimes and agentOS Hosted VMs. On October 5 it said 3.0 would replace NATS with S3. The October 26 3.0 Preview delivers that: a new storage engine, WarpDrive, promises bottomless storage on S3 at SSD speed, and Rivet becomes a single stateless binary.
◆ Where it's heading
Each release removes operational burden: BYOC moved the control plane into the customer's cloud, and 3.0 reduces the self-hosted footprint to one binary plus an S3 bucket. The agent work (Pi, agentOS) sits on top as the main workload Rivet is courting.
◆ Prediction
Expect benchmarks and migration guidance for 2.x users during the preview, followed by a 3.0 GA. The entry gives no performance numbers, so the SSD-speed claim is unverified.
