Oxynote is a new open-source (Apache-2.0) internal wiki for engineering teams. A page can include a chart that runs its own query against Prometheus, PostgreSQL, MySQL, or MariaDB right next to the explanatory text, and changes to important pages go through a draft, a diff, and approval, like a pull request.
Internal docs go stale because people open them only when something breaks. Live data gives the team a reason to open a page every day, and pages read daily stay up to date. How it works with PostgreSQL: * Live Metrics blocks run SQL against your PostgreSQL databases and show the result as a time series, bar chart or gauge. * Queries can use Grafana-style macros such as `$__timeFilter`, `$__timeGroup` and `$__timeFrom`, so existing dashboard queries carry over. * Oxynote only connects to read-only data sources: a role or database with `default_transaction_read_only` enabled, or a standby. Every session also runs in read-only mode. * Oxynote stores its own data in PostgreSQL 18, which is embedded in the all-in-one Docker image. A typical use is a runbook that shows replication lag or slow query counts next to the steps for handling them, so the chart and its explanation are reviewed together. Oxynote is available from: * [Source and install instructions](https://github.com/oxynote/oxynote) * [Latest release](https://github.com/oxynote/oxynote/releases)
