Introduction
On this page you can see the beating heart of sanger-tol - the size of our community and the output of our work.
Please bear in mind the following points when looking over these numbers:
- Pipelines maybe worked on before they are transferred to sanger-tol. The age, stars and other metrics of the original parent repository are not shown.
- Metrics are for the default (
main) branch only - Commits and contributors are only counted if associated with a GitHub account
nextflow pullandnextflow runuses git to clone a remote repo the first time it runs, so the clones count gives some idea of usage. However:- Unique cloners is based on IP address, so will under-represent institutional users sharing a single external IP address
- Unique cloners is based on IP address, so will over-represent cloud users using multiple IP addresses
- Traditional HPC centres may share workflow installations, so only have one clone for many users / pipeline runs
- Cloud users will typically spin up a new instance and clone the workflow every time that they run a pipeline.
- Clone counts and repositoriy views are only available for two weeks - longer term data collection for sanger-tol repos started in July 2023 This is when we started counting the totals.
- Metrics are fetched once per day (last checked 2025-08-15).
Community
The numbers below track our growth over the various channels that the sanger-tol community operates in.
Click a number to see how the community has grown over time
GitHub organisation members
We use GitHub to manage all of the code written for sanger-tol. It's a fantastic platform and provides a huge number of tools. We have a GitHub organisation called sanger-tol.
It is not required to be a member of the sanger-tol GitHub organisation to contribute. However, members get the sanger-tol logo listed on their profile page and full write-access to all sanger-tol repositories.
By default, organisation membership is private. This is why you'll see a lower number if you visit the sanger-tol organisation page and are not a member.
GitHub contributors
Anybody can fork sanger-tol repositories and open a pull-request. Here we count how many different people have contributed at least one commit to an sanger-tol repository, or created or commented on an issue or pull-request.
Plot truncated to start of 2022 (some pipelines moved to sanger-tol so have older contributions).
Code stats
Whilst we always prefer quality over quantity, these numbers reflect the work output from the sanger-tol community.
Repository traffic
Every time a nextflow user pulls a sanger-tol pipeline, the repository is cloned. Here we can track how much that happens across all sanger-tol repositories. Please note that these numbers come with some caveats [ see more ].
Additionally, GitHub tracks how many times people view repository web pages on github.com.
Pull Requests
When people contribute code to a sanger-tol repository, we conduct a "Pull request" - other members of the sanger-tol community review the proposed code and make suggestions, before merging into the main repository.
Pull Request response times
Pull-requests are reviewed by the sanger-tol community - they can contain discussion on the code and can be merged and closed. We aim to be prompt with reviews and merging. Note that some PRs can be a simple type and so very fast to merge, others can be major pipeline updates.
First response is when a comment is made by a GitHub user other than the original PR author
Issues
GitHub issues can be created to log feature requests, bug reports or questions.
Issue response times
A sign of an active community is a quick response time to issues. Here we see a frequency histogram of how long it takes to respond to and close issues.
First response is when a comment is made by a GitHub user other than the original issue author
Contributor Leaderboard
We value each and every contribution to sanger-tol, no matter how small. However, that doesn't mean that we can not get competitive!
Here are the latest stats of who has contributed the greatest number of commits.
Remember
- There is more to contributing than commits! We're not counting issue comments, reviews or anything else here.
- People merging pull-requests get bonus commit counts from those merge commits.
- Some people commit often, others not so much. So it's not a perfect representation of amount of work - just a bit of fun!
mainbranch only, and all of the other caveats..
