Eureka vs Sanity
A side-by-side editorial comparison of Eureka and Sanity — release velocity, themes, recent moves, and the top alternatives to consider.
Eureka vs Sanity: at a glance
What is Eureka?
Eureka cut its first release in two years, and the notes live in a release candidate, not the tag.
Netflix's Eureka reached v1.10.19 in August 2026 after a candidate train that started in January 2024. The final tag's body is a single CI fix — the JDK setup in the publish workflow — byte-identical to rc.6 before it. The actual accumulated changes sit in rc.4: replacing servo with spectator in the client, EIP support for secondary ENIs, allocation-reduction backports from the 2.x line, VIP address lookup metrics, and xstream upgrades clearing two CVEs.
What is Sanity?
Sanity's MCP server now explains failed validations and stops skipping them.
Sanity made Context Knowledge Bases generally available on November 10, letting agents read datasets, websites and files over MCP. The days since have been follow-up: MCP server 2.46.1 and 2.46.2 return stable error codes, explain incomplete validations and stop writes from skipping schema checks, while the console now shows when each robot token was last used. Media Library made PDF previews zoomable and folder counts in big libraries about seven times faster.

Eureka

◆ Current state
Netflix's Eureka reached v1.10.19 in August 2026 after a candidate train that started in January 2024. The final tag's body is a single CI fix — the JDK setup in the publish workflow — byte-identical to rc.6 before it. The actual accumulated changes sit in rc.4: replacing servo with spectator in the client, EIP support for secondary ENIs, allocation-reduction backports from the 2.x line, VIP address lookup metrics, and xstream upgrades clearing two CVEs.
◆ Where it's heading
This is a maintenance-mode project shipping a catch-up release rather than a roadmap. The substantive content is backports and dependency hygiene — the perf work is explicitly ported from 2.x, and the last two candidates exist only to bump xstream and fix the publish pipeline. The 2.0.x line saw its own small patch, so both lines are alive but neither is being extended.
◆ Prediction
Direction is hard to read from a feed where the release tag carries less information than its candidates. The pattern suggests further releases will be driven by CVE remediation in transitive dependencies rather than by feature work.
Sanity
6.3DEVOPS
Sanity's MCP server now explains failed validations and stops skipping them.
◆ Current state
Sanity made Context Knowledge Bases generally available on November 10, letting agents read datasets, websites and files over MCP. The days since have been follow-up: MCP server 2.46.1 and 2.46.2 return stable error codes, explain incomplete validations and stop writes from skipping schema checks, while the console now shows when each robot token was last used. Media Library made PDF previews zoomable and folder counts in big libraries about seven times faster.
◆ Where it's heading
Sanity is making the agent-facing parts dependable: the MCP server is getting the error codes and validation rules a production client needs. Access visibility for tokens and members follows the same push to let teams audit what automated clients do.
◆ Prediction
Expect more MCP server point releases around validation and Knowledge Base commands, and more usage data on tokens and agents in the console.
