NATS vs Nominatim
A side-by-side editorial comparison of NATS and Nominatim — release velocity, themes, recent moves, and the top alternatives to consider.
NATS vs Nominatim: at a glance
What is NATS?
NATS second release candidates add a config reload check and faster redelivery queues.
NATS keeps the 2.14 and 2.15 lines in step, and on November 6 both got a second release candidate. The RCs make filtered filestore scans skip non-matching messages, stop redelivery queues from copying whole backlogs on each dequeue, and fix AckAll and gateway interest bugs. 2.15.3-RC.2 also adds a -t --test_reload flag that tells operators whether a config change needs a restart.
What is Nominatim?
Nominatim 5.3.3 turns off its debug view by default because it can leak server details.
Nominatim releases a minor every few months with hotfixes when the update path breaks. 5.3.3, the first entry since April, restores compatibility with the latest SQLAlchemy and fixes reverse geocoding near overlapping POIs, POIs parented to unnamed streets, TIGER parent streets and rank-11 boundaries. It also tightens API parameter validation, output escaping and overlong query terms, and makes one breaking change: the debug view is now off unless NOMINATIM_SERVE_DEBUG_OUTPUT is set.

NATS
5.0DEVOPS
NATS second release candidates add a config reload check and faster redelivery queues.
◆ Current state
NATS keeps the 2.14 and 2.15 lines in step, and on November 6 both got a second release candidate. The RCs make filtered filestore scans skip non-matching messages, stop redelivery queues from copying whole backlogs on each dequeue, and fix AckAll and gateway interest bugs. 2.15.3-RC.2 also adds a -t --test_reload flag that tells operators whether a config change needs a restart.
◆ Where it's heading
The project is in a hardening stretch on both lines, with JetStream efficiency and correctness fixes landing alongside small operator tools. Account-hash subject mappings from RC1 remain the main new routing feature heading to release.
◆ Prediction
Expect 2.15.3 and 2.14.10 final releases shortly, carrying the RC2 fixes and the reload check.
Nominatim
2.5DEVOPS
Nominatim 5.3.3 turns off its debug view by default because it can leak server details.
◆ Current state
Nominatim releases a minor every few months with hotfixes when the update path breaks. 5.3.3, the first entry since April, restores compatibility with the latest SQLAlchemy and fixes reverse geocoding near overlapping POIs, POIs parented to unnamed streets, TIGER parent streets and rank-11 boundaries. It also tightens API parameter validation, output escaping and overlong query terms, and makes one breaking change: the debug view is now off unless NOMINATIM_SERVE_DEBUG_OUTPUT is set.
◆ Where it's heading
Since the move to a Python package was completed in 5.0, releases have concentrated on geocoding quality and the update pipeline. 5.3.3 adds a security-minded layer, validating and escaping API input and output and closing the debug view, which suggests operators running public instances are now a design concern. No migrations are needed, keeping upgrades cheap.
◆ Prediction
Expect a 5.4 minor to continue query-parser and update-pipeline work; the hardening in 5.3.3 may extend to further API defaults.
