Prometheus vs Sanity
A side-by-side editorial comparison of Prometheus and Sanity — release velocity, themes, recent moves, and the top alternatives to consider.
Prometheus vs Sanity: at a glance
What is Prometheus?
Prometheus 3.16 ships GA with query cost limits behind a flag and stable Smoothed/Anchored selectors
Prometheus 3.16.0 went GA on 4 November after four release candidates. It makes Smoothed and Anchored vector selectors stable and always-on, adds experimental query cost estimation with configurable execution limits, an experimental integral() function, per-query start-timestamp overrides and metadata-wal-records in Agent mode. The rest is TSDB correctness fixes for out-of-order samples and a long list of scrape and remote-write performance work.
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.

Prometheus

Prometheus 3.16 ships GA with query cost limits behind a flag and stable Smoothed/Anchored selectors
◆ Current state
Prometheus 3.16.0 went GA on 4 November after four release candidates. It makes Smoothed and Anchored vector selectors stable and always-on, adds experimental query cost estimation with configurable execution limits, an experimental integral() function, per-query start-timestamp overrides and metadata-wal-records in Agent mode. The rest is TSDB correctness fixes for out-of-order samples and a long list of scrape and remote-write performance work.
◆ Where it's heading
The 3.16 cycle makes PromQL cost measurable before making it enforceable: subquery samples now count toward statistics, and limits ship behind --enable-feature=query-cost. Remote Write 2.0 keeps dropping legacy metadata metrics, and the 3.15.x and 3.13 LTS lines move separately on security rebuilds.
◆ Prediction
Expect 3.15.x and 3.13.x security patches next and a 3.17 rc within weeks; whether query-cost leaves its flag depends on feedback the entries do not yet show.
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.
