Agile delivery
Minerva
Plan and ship work with projects, configurable issue types, Scrum and Kanban boards, sprints, releases and a roadmap.
About MinervaEarly development
Delivery, knowledge and support. On your own infrastructure.
Castra is an open-source, self-hosted suite: Minerva for agile delivery, Caelus for documentation and Mercury for service desk. One platform, one sign-in, one audit log.
Three tools
Use one, or all three. Each has its own colour and its own job.
Knowledge hub
Caelus
Write together in spaces and page trees. Pages are stored as Markdown, history shows word-level diffs, and live Minerva and Mercury data can be embedded.
About CaelusService desk
Mercury
Run requests, incidents, problems and changes with queues, SLAs, a requester portal and strict rules on who can see what.
About MercuryOne platform underneath
Sign-in, access, audit and links work the same way across all three tools.
- Multi-tenant: platform, organisation, project
- Single sign-on with any OIDC provider (Keycloak is the reference)
- Directory groups mapped to roles by project admins
- Tamper-evident audit log
- Smart links with live previews across tools
Runs where you do
Castra runs fully on your own infrastructure. Start on a single host with Docker Compose, scale to Kubernetes, or swap in managed cloud services.
No outside calls
No CDN, no telemetry and no licence server. It works air-gapped.
Open protocols
Postgres, S3, the Redis protocol, OIDC, SCIM, SMTP and OpenTelemetry.
One image, many roles
Run the roles together or scale each one on its own.
Moving from Atlassian
Castra is a self-hosted alternative to Jira Software, Confluence and Jira Service Management. The mapping is direct.
| If you use | Look at |
|---|---|
| Jira Software | Minerva, agile delivery |
| Confluence | Caelus, knowledge hub |
| Jira Service Management | Mercury, service desk |
There is no import tool from Atlassian products yet.
Try it on your own hardware
Castra is in early development. The quick start is on the self-hosting page and may change.
