linkding

Minimal self-hosted bookmark manager with LD_* env config and a documented REST API.

Free

Use it when
  • you want a bookmark service on a Raspberry Pi that an agent can post links to with a token
  • you left Pinboard or del.icio.us and want tags, notes, and archives without a heavy stack
An agent cannot reach
  • Import and export Netscape HTML
  • User administration
Gotchas
  • Single-maintainer project that declines features outside its scope (README)
  • Local HTML archiving requires the single-file sidecar image variant (linkding:latest-plus)
  • Managed hosting on linkding.link is third-party (not a Builder edition)

Karakeep

Self-hosted bookmark-everything app with an official MCP server, CLI, and REST API.

Free

Use it when
  • you want an agent to file every link you send it into lists and tags on a server you control
  • you are replacing Pocket or Omnivore and want full-page archives with LLM tagging from a local Ollama
An agent cannot reach
  • Subscribe to RSS feeds for auto-hoarding
  • Rule engine, webhooks, and user administration
Gotchas
  • AGPL-3.0: a modified instance you host for others must publish its source
  • docker-compose expects Meilisearch and a headless Chrome sidecar; without them search and crawling degrade
  • MCP server exposes tools only, no resources; RSS feeds, rules, and admin stay in the UI or REST API

Linkwarden

Collaborative bookmark manager that preserves pages, with an official REST API and a paid cloud edition.

Self-hosted · Cloud

Use it when
  • your team collects research links and needs the pages preserved even after they vanish
  • you want an agent saving links with tags into shared collections through a plain REST API
An agent cannot reach
  • AI tagging

1 more job is undetermined.

Gotchas
  • AGPL-3.0
  • Archiving runs a Playwright browser; expect memory use and a separate worker
  • SSO is limited to enterprise and self-hosted users
  • Community MCP wrappers (ni-c/linkwarden-mcp, homeserverhq/linkwarden-mcp) have near-zero stars; use the REST API directly
