Real-time Open Source Indexes: Databases, Headless CMSs and Static Site Generators

Hi COSS Community!

Here at Runa Capital every quarter we publish ROSS Index - the fastest-growing open-source startups by Github stars ⭐. ROSS index appeared to be a decent predictor for future rounds as around 40% of early-stage startups raised $750M+ totally after being mentioned in the index. But it has some inevitable flaws. Github stars are barely a community strength metric and manual quarterly updates are hardly scalable. So we decided to take a step forward and create a few more OSS indexes, which will be updated automatically and based on the most important metrics for open-source projects — contributors.

Now we present the first three open-source indexes — databases, headless CMSs and static site generators.

Open-Source Database Index

We have published Open-Source Database Index with daily updated metrics, and there are 3 clear leaders with the highest number of active contributors:

  1. ClickHouse (349 active contributors). Originated in 2009 at Yandex and now developed by ClickHouse, Inc. (valued at $2B in 2021).
  2. Spark SQL (302 active contributors). Founded in 2009 at UC Berkeley and commercialized by Databricks (valued at $38B in 2021).
  3. ElasticSearch (257 active contributors). Founded in 2010, developed and commercialized by Elastic (NYSE: ESTC, $7.2 market cap).
