Questions

Which projects does this track?

Open-source projects under the data and AI stack: engines (DuckDB, Spark, Flink, Trino, Polars), table formats (Iceberg, Delta Lake, Hudi), Kafka, pipelines (Airflow, dbt, Dagster, Prefect, Airbyte), databases (ClickHouse, Redis, Valkey, MongoDB, CockroachDB), search and vector (Elasticsearch, OpenSearch, Milvus, Qdrant), infrastructure (Terraform, OpenTofu, Vault, OpenBao, MinIO), model serving (vLLM, SGLang, llama.cpp, Ollama), frameworks (PyTorch, JAX, Transformers, Ray, MLflow, LangChain, LlamaIndex) and Superset.

Which projects changed their license?

Elasticsearch (Apache 2.0 to SSPL or the Elastic License in 2021, AGPL added in 2024), Redis (BSD to RSAL or SSPL in 2024, AGPL added in 2025), Terraform and Vault (MPL 2.0 to the Business Source License in 2023), CockroachDB (to the BSL in 2019, to the CockroachDB Software License in 2024), MongoDB (AGPL to SSPL in 2018), MinIO (Apache 2.0 to AGPL in 2021) and Airbyte (MIT to the Elastic License, 2021 and 2025). Each change links to the commit that changed the LICENSE file.

Which projects are forks made after a license change?

OpenSearch (from Elasticsearch 7.10.2, 2021), OpenTofu (from Terraform, 2023), OpenBao (from Vault, 2023) and Valkey (from Redis 7.2.4, 2024). Each now lives at a foundation.

What is the difference between open source and source-available?

Open source here means at least one of the licenses offered is approved by the Open Source Initiative (MIT, Apache 2.0, BSD, MPL, AGPL and so on). Source-available licenses such as the Business Source License, SSPL, the Elastic License or RSAL publish the code but limit how it can be used, typically offering it as a service.

How are stars per week measured?

From weekly snapshots of GitHub star counts: stars added between two readings at least six days apart, per week. Until two snapshots exist, the figure comes from OSS Insight's weekly star history for the three weeks to September 21, 2026, and is labelled as such.

Can I use the data in my own tools or agents?

Yes. There is a public JSON API with an OpenAPI spec, llms.txt for language models, and a For AI agents page with copy-paste examples. Please cite Repos (repos.fru.dev).

Something is wrong or missing. How do I fix it?

Every project page has Suggest a correction, and the listing pages have Suggest a missing project. Each suggestion is checked against the source before anything changes.

License changes by email

Only when a tracked project changes its license, foundation or name, at most once a week.
