SilverBullet review
A flexible Markdown knowledge base for users comfortable with self-hosting and scripting.
Reviewed by iTechGuides Editors · Editorial team · Updated Nov 2026
SilverBullet is an open-source, self-hosted knowledge management and note-taking application built around Markdown files. It is designed for individuals and teams that want control over where notes are stored, how pages are structured, and how the workspace can be extended. The browser-based editor supports live preview, wiki-style bidirectional links, outlining, task management, objects, queries, and programmable pages. Its Progressive Web App supports offline access, while the listed platforms include web, Windows, macOS, Linux, iOS, Android, and self-hosted deployments.
Its strongest distinction is the depth of its programmable knowledge-base model. Lua scripting can add commands, templates, and widgets, while sandboxed web-worker plugs provide another extension path. Built-in queries and objects support structured information alongside ordinary Markdown pages, making SilverBullet more suitable for interconnected personal knowledge bases and customized workflows than for simple, linear note capture. Notes are stored as files on disk, and page sharing and publishing work through HTTPS and GitHub.
Collaboration is supported through shared spaces for multiple authenticated users, near-real-time propagation, and three-way merging of concurrent edits. That approach can help preserve changes when people edit at the same time, but it is not intended to replicate classic Google Docs-style collaborative editing. SilverBullet follows an open-source model rather than conventional paid tiers, so its main tradeoff is operational: users choose the flexibility of self-hosting instead of a managed service experience. Pick it for extensibility, offline-first access, and Markdown ownership; choose an alternative if you want broad integrations, managed hosting, or document-style real-time collaboration.
