What we're building now
A studio update on today's MDG Labs lineup, with license and status for each. SlugBase, Hoserva, Release Ops and sqlite-migrate, and why not all of them are open-core.
What we’re building now
The lineup has changed since this blog started, and some earlier posts now point here. This is the current picture: what we build, under which license, and how far along each piece is. The lineup is narrower than it was. What is listed here is what we are working on.
The lineup
| What it is | License | Status | |
|---|---|---|---|
| SlugBase | Bookmark manager with short-URL forwarding | Elastic License 2.0 | In development, source available, Cloud coming soon |
| Hoserva | Home server platform for mixed-size disks | AGPL-3.0 | In development, no release yet |
| Release Ops | Self-hosted release monitor | AGPL-3.0 | v0.1.0, released 2026-10-07 |
| sqlite-migrate | SQLite schema migration tool | MIT | v0.1.3 |
SlugBase
A bookmark manager with optional short-URL forwarding. The source is public on GitHub under the Elastic License 2.0, which makes it source-available, not open source in the strict sense. You can self-host it today. SlugBase Cloud, the managed tier, is coming soon at slugbase.app. SlugBase itself is in development. More on the SlugBase page.
Hoserva
An open-source home server platform for mixed-size disks: a management layer with a Go daemon, a CLI and a web UI over mergerfs and SnapRAID on Debian. It is AGPL-3.0, in development and has no release yet. The storage core and the NAS features are built; apps and a guided migration from Unraid are the current phase. The introduction post goes into the details, and the Hoserva page has the summary.
Release Ops
A self-hosted release monitor with a web UI. It polls releases on GitHub, GitLab, Gitea, Forgejo and Codeberg, and creates a ticket in Kaneo, Jira or Linear when a real new release ships. It runs as a single Docker container on SQLite. It is AGPL-3.0, and v0.1.0 was released on 2026-10-07. See the Release Ops page, the source on GitHub and the docs.
sqlite-migrate
A small developer tool, not a product: a Go CLI and embeddable library that generates and safely applies SQLite schema migrations from a plain-SQL schema.sql. It rebuilds tables automatically for changes ALTER TABLE cannot express, requires every table to be STRICT, and apply defaults to a dry run. It is MIT-licensed, the latest release is v0.1.3, and it lives on GitHub with docs. It has no page here because there is no UI or hosted offering to describe.
Open-core describes SlugBase
The post on why we build open-core describes the model behind SlugBase: one codebase, Community Edition you host yourself, and a managed Cloud, coming soon, for people who want the product without the ops. That model needs a Cloud to exist.
So the split is simple. A product with a hosted tier next to a self-hosted edition is open-core, as SlugBase is. A product that is only software you run is plain self-hosted open source, as Hoserva and Release Ops are. sqlite-migrate is a library and a CLI under MIT, so there is nothing to host at all.
What’s next
Hoserva’s open work is apps and the migration from Unraid. Release Ops is at v0.1.0, released on 2026-10-07, and sqlite-migrate at v0.1.3. We will write about each when there is something worth saying, and status on this blog will stay as plain as it is here.
