This is a monthly newsletter about the current state of Radicle CI, what has happened recently, and near future plans.
Current status
Radicle CI is in production use. There are several CI nodes, and Lars runs a
public one for open source projects at callisto.liw.fi. It is now open to
all open source projects, not just Rust projects.
CI node leaderboard
(Unfortunately, the node that collects CI run data is currently not running, but will return, hopefully soon. The data hasn't been updated.)
This is a demonstration of a leaderboard of CI nodes that have opted into being on the board. For privacy reasons I won't publish node IDs whose owners haven't opted in. But the next version may have securely anonymized node identifiers for those who don't opt in.
Tell Lars if you want your CI node to be included.
Total 23561 CI runs across all nodes.
| Pos | Node ID | Alias | CI run count |

Radicle CI use metrics
I track Radicle CI use by counting job COBs that reach a public seed node run by Adrian. The data below excludes CI runs on my own CI nodes, to avoid skewing the numbers. I run CI a lot, as part of developing Radicle CI.
The data is collected in the
job-cob-data repository by the job-cob-counts software.

Office hours
Radicle CI office hours are on hold for now.
Overview of the past month
For the next month, Lars has worked on fixing the issue backlogs in the various CI components.
Goals for 2026 (unchanged)
The primary goal for Radicle CI in 2026 is to get more people using it. To achieve this, much work is needed to improve awareness, documentation, installation, configuration, and operation. Some feature work and bug fixing will also be needed. While the basics work and are in use, things could be much more polished.
In addition, a supporting goal is to start tracking how much Radicle CI is used, based on job COBs.
Future plans
For the next month, Lars plans to work on getting Radicle CI used more. This will involve updates to documentation and targeted demos and tutorials, such as setting up CI for a Radicle repository.
Notes
If you have an open source project and want to try Radicle and Ambient on
callisto, see callisto.liw.fi for instructions.
