Silverbullet

SilverBullet is a self-hosted web app that blends a clean Markdown editor with wiki-style linking, a built-in query language, and a Lua scripting environment. It's aimed at people who want more than a static notes app but don't want to stitch together separate tools to get there.

Your notes live as Markdown files in what SilverBullet calls a "space." You can browse them like a traditional app or follow bi-directional links like a wiki. The live-preview editor keeps things readable while you write, and a page picker lets you jump around quickly.

What sets it apart from tools like Logseq or SiYuan is the depth of its programmability:

• Space Lua scripting lets you write custom logic directly inside your notes, generating content dynamically at render time.
• SLIQ (Space Lua Integrated Query) lets you query your own notes like a database, pulling in tasks, tags, or page metadata on the fly.
• Templates can be driven by queries, so a "product features" page or a "recent pages" list stays current without manual updates.
• Bi-directional links connect pages automatically, and linked mentions surface everywhere a page is referenced.
• Tagging and custom attributes let you annotate pages with structured data that queries can sort, filter, and display.
• Task tracking works across your entire space, so you can collect incomplete tasks from all your pages in one view.

SilverBullet runs as a single self-contained server or container, which means you deploy it on a VPS, a Raspberry Pi, or anywhere you control. Your data stays yours. There's no account to create, no sync service to trust.

It's a good fit for writers who want structure without friction, for outliners who need hierarchy, and especially for people comfortable writing a little Lua who want their notes to do real work.
