Raneto
Raneto is a lightweight, file-based markdown knowledge base for Node.js with built-in search, a browser-based editor, and optional authentication. It's designed for self-hosted deployments where content is stored as markdown files rather than in a database.

What Raneto is
Node.js application that serves markdown files as a wiki, featuring full-text search, optional session-based authentication, configurable via environment variables, and an optional in-browser markdown editor. Stateless file-based architecture eliminates database dependencies.

Best use cases
Implementation considerations
- Session secret must be at least 32 characters; use `openssl rand -base64 32` to generate. Rotate regularly in production.
- Content directory path is configurable via `CONTENT_DIR` env var; ensure Node.js process has read/write permissions and the directory is backed up.
- Browser-based editor is optional; disable `ALLOW_EDITING` in production if content is managed offline or via Git only.
- Authentication defaults to disabled; enable with `AUTHENTICATION=true` and set `ADMIN_USERNAME` and `ADMIN_PASSWORD` via env vars.
- Default address is `127.0.0.1:8080`; expose via reverse proxy (nginx, Caddy) in production for SSL termination and access control.
When to avoid it — and what to weigh
- Real-time collaborative editing required — Raneto's file-based approach does not support simultaneous multi-user editing. Concurrent writes to the same markdown files risk conflicts.
- Complex permission models needed — Authentication is simple username/password. Fine-grained role-based access control, team-based permissions, or LDAP/SAML integration are not present.
- High-traffic, multi-tenant SaaS deployment — File I/O and search operations scale poorly with thousands of concurrent users or massive document volumes. No caching, CDN, or horizontal scaling strategy documented.
- Advanced content features required — No support for versioning, audit trails, custom metadata, or structured data. Limited to plain markdown rendering without extensive plugin ecosystem.

DEV.co evaluation signals
Editorial assessment — not user reviews. Directional, with an explicit confidence level.
| Signal | Assessment |
|---|---|
| Maintenance | Active |
| Documentation | Adequate |
| License clarity | Clear |
| Deployment complexity | Low |
| DEV.co fit | Good |
| Assessment confidence | High |
Session secret must be strong and rotated; default `127.0.0.1` binding limits exposure. Authentication is basic username/password; no multi-factor auth or modern OIDC/SAML support. Markdown editor allows arbitrary file writes; restrict `ALLOW_EDITING` in untrusted environments. No explicit security audit, vulnerability disclosure policy, or security update frequency documented. Dependencies should be reviewed for CVEs via FOSSA or npm audit.
Alternatives to consider
Docusaurus
Markdown-based documentation site generator with better SEO, versioning, and multi-language support. Requires build step but scales better for large docs.
BookStack
PHP-based wiki with database backend, more granular permissions, user management, and a rich web UI. Better suited for teams and non-technical users.
Outline
Modern, collaborative wiki built on React and Node.js with real-time editing, teams, and integrations. Requires more infrastructure but supports concurrent editing.
