Page: alternatives/raindrop-io.html

## linkding

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

- Listing: apps/sissbruecker--linkding.html
- JSON: apps/sissbruecker--linkding.json
- License: MIT
- Agent interface: API, from the builder
- Reach: 8 of 10 jobs
- Last activity: 2026-09-03
- Effort: config-only
- Agent cannot reach: Import and export Netscape HTML; User administration
- Use it when: you want a bookmark service on a Raspberry Pi that an agent can post links to with a token
- Use it when: you left Pinboard or del.icio.us and want tags, notes, and archives without a heavy stack
- Gotcha: Single-maintainer project that declines features outside its scope (README)
- Gotcha: Local HTML archiving requires the single-file sidecar image variant (linkding:latest-plus)
- Gotcha: 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.

- Listing: apps/karakeep-app--karakeep.html
- JSON: apps/karakeep-app--karakeep.json
- License: AGPL-3.0
- Agent interface: MCP server, from the builder
- Reach: 8 of 10 jobs
- Last activity: 2026-08-31
- Effort: config-only
- Agent cannot reach: Subscribe to RSS feeds for auto-hoarding; Rule engine, webhooks, and user administration
- Use it when: you want an agent to file every link you send it into lists and tags on a server you control
- Use it when: you are replacing Pocket or Omnivore and want full-page archives with LLM tagging from a local Ollama
- Gotcha: AGPL-3.0: a modified instance you host for others must publish its source
- Gotcha: docker-compose expects Meilisearch and a headless Chrome sidecar; without them search and crawling degrade
- Gotcha: 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.

- Listing: apps/linkwarden--linkwarden.html
- JSON: apps/linkwarden--linkwarden.json
- License: AGPL-3.0
- Agent interface: API, from the builder
- Reach: 8 of 10 jobs
- Last activity: 2026-09-02
- Effort: config-only
- Agent cannot reach: AI tagging
- Use it when: your team collects research links and needs the pages preserved even after they vanish
- Use it when: you want an agent saving links with tags into shared collections through a plain REST API
- Gotcha: AGPL-3.0
- Gotcha: Archiving runs a Playwright browser; expect memory use and a separate worker
- Gotcha: SSO is limited to enterprise and self-hosted users
- Gotcha: Community MCP wrappers (ni-c/linkwarden-mcp, homeserverhq/linkwarden-mcp) have near-zero stars; use the REST API directly
