Manticore Search vs Nacos
A side-by-side editorial comparison of Manticore Search and Nacos — release velocity, themes, recent moves, and the top alternatives to consider.
Manticore Search vs Nacos: at a glance
What is Manticore Search?
Manticore 31.0.7 undoes a 2x COUNT(DISTINCT) slowdown its own collation fix caused.
Manticore Search's 31.x tags so far are fixes rather than features. 31.0.3 and 31.0.4 were CI and packaging work; 31.0.7 restores string COUNT(DISTINCT) speed after the 29.18.5 collation fix made it 2x slower (1.1 s to 2.4 s on the logs10m benchmark) by calling tolower() per byte. A lookup table replaces the call without changing hash values, so secondary indexes and histograms stay compatible.
What is Nacos?
Nacos is hardening the AI registry it just built, and closing the door behind its deprecated APIs.
Nacos has finished turning a microservice registry into a registry for AI agents — MCP, Skill, Prompt and Agent resources all live under one AI Registry — and the 3.2 line is now spending its releases making that surface safe to operate. The newest patch adds server-identity authentication to internal JRaft traffic, puts MCP tool imports from private addresses behind an administrator allowlist, and returns HTTP 410 on deprecated AI APIs by default. The 2.x line runs in parallel as a JDK 8 maintenance branch that receives only backported fixes.

Manticore Search
5.0DEVOPS
Manticore 31.0.7 undoes a 2x COUNT(DISTINCT) slowdown its own collation fix caused.
◆ Current state
Manticore Search's 31.x tags so far are fixes rather than features. 31.0.3 and 31.0.4 were CI and packaging work; 31.0.7 restores string COUNT(DISTINCT) speed after the 29.18.5 collation fix made it 2x slower (1.1 s to 2.4 s on the logs10m benchmark) by calling tolower() per byte. A lookup table replaces the call without changing hash values, so secondary indexes and histograms stay compatible.
◆ Where it's heading
October has been correctness work on string handling (range filters, collation-aware COUNT(DISTINCT)) followed by fixing the performance cost of those fixes. The 31.x line still appears in the feed without notes on what features justified the major version.
◆ Prediction
Expect more 31.0.x patches in this vein. What new capability defines 31.x remains unclear from these entries.
Nacos
6.3DEVOPS
Nacos is hardening the AI registry it just built, and closing the door behind its deprecated APIs.
◆ Current state
Nacos has finished turning a microservice registry into a registry for AI agents — MCP, Skill, Prompt and Agent resources all live under one AI Registry — and the 3.2 line is now spending its releases making that surface safe to operate. The newest patch adds server-identity authentication to internal JRaft traffic, puts MCP tool imports from private addresses behind an administrator allowlist, and returns HTTP 410 on deprecated AI APIs by default. The 2.x line runs in parallel as a JDK 8 maintenance branch that receives only backported fixes.
◆ Where it's heading
Two threads are running at once: 3.3.0-BETA is extending the registry to protocol-neutral agent registration and vector-based resource discovery, while 3.2.x closes off the compatibility and security debt that the fast AI-registry build-out accumulated. The breaking notice in 3.2.4 — an irreversible JRaft authentication transition and 410s on legacy endpoints — reads as the project deciding the AI surface is stable enough to stop carrying old shapes. Operator-facing work, not new capability, is where the 3.2 series is heading.
◆ Prediction
Expect 3.3.0 to go final on the agent-registration and vector-discovery work while 3.2.x keeps shipping security hardening; the temporary nacos.core.api.compatibility.enabled switch is the obvious next thing to be removed.
