Raindrop.io vs Cowpin: Collections vs Flat Tags (and Which API You Get)

Raindrop.io is alive, actively maintained, and good at what it does. This is not a shutdown post. If nested collections, cover tiles, and Raindrop's native apps are the workflow you love, stay — Cowpin is deliberately different, not "Raindrop but cheaper."

This page is for the decision you actually face: folder-like collections vs a flat tag space, and Raindrop's REST API vs a Pinboard-compatible API that existing bookmark scripts already speak.

Collections vs flat tags

	Raindrop.io	Cowpin
Mental model	Nested collections (folders) + optional tags	Flat tags + bundles (saved tag groups)
Visual browse	Cover images, grid, strong mobile UI	Text-first lists and reader; no cover grid
Filing speed at 5k+ saves	Drill into collection tree	Type `#tag` once; multiple tags per save without picking one folder
Import from Raindrop HTML	—	Each collection becomes a tag (including nested collections)

Raindrop optimizes for browsing what you saved. Cowpin optimizes for finding text again — full-text search on archived page text, semantic search on the AI plan, and Rediscover surfacing old saves.

Neither model is "correct." Power users who outgrow folders often want many tags per link without duplicating the bookmark into three collections. People who think in albums and mood boards usually want Raindrop.

Search and archive (check pricing before you decide)

Raindrop's free plan is unusually generous: unlimited bookmarks and collections on unlimited devices (Raindrop pricing FAQ).

Raindrop Pro adds full-text search (including indexed video speech on their marketing), permanent copies, larger uploads, cloud backup, and cleanup tools — billing via Paddle, monthly or yearly (yearly is typically ~20% less).

Cowpin charges from a 14-day full trial (no card), then $22/year for the Pinboard-equivalent core: unlimited saves, full-text search on archived text, tags, export, public RSS, and a Pinboard-compatible API. An optional AI & Archive add-on ($29/year on top of base) adds semantic search, Ask-with-citations, AI summaries, higher AI tag quotas, and on-demand full-page HTML snapshots. See pricing for current numbers.

Honest trade: Raindrop gives you a polished free tier forever; Cowpin bets on paid-from-trial like Pinboard — fewer free riders, more margin to keep export and API stable.

APIs: different shapes, different ecosystems

	Raindrop API	Cowpin API
Style	Raindrop-native REST (developer.raindrop.io)	Pinboard-compatible `/api/v1/*`
Best for	Apps built for Raindrop, OAuth collections, Raindrop automations	Scripts, legacy Pinboard clients, Zapier-style "add bookmark" flows, MCP tools
Auth	Raindrop OAuth / tokens per their docs	API tokens; same endpoints Pinboard users already document on the web

If you already run automations against Pinboard's API shape, Cowpin is a drop-in target. If you live inside Raindrop's ecosystem, their API is the right tool — switching means rewriting integrations, not renaming endpoints.

Export and lock-in

Both services let you leave with data:

Raindrop: Settings → Export → HTML (Netscape format) or CSV. Highlights are not in the HTML file; CSV can carry notes/highlights Raindrop puts in that export.
Cowpin: Export anytime (HTML, Pinboard JSON, highlights Markdown, etc.).

Step-by-step Raindrop → Cowpin: /migrate/raindrop. Broader "nshould I leave?" framing: Raindrop alternative.

Who should pick which

Stay on Raindrop if: collections + visuals are the product for you; Pro features justify the subscription; you're happy with Raindrop's API for your automations.

Try Cowpin if: you want tag-first filing, Pinboard-compatible automation, full-text search on the base plan after trial, and a library built around text archive + export rather than cover art.

Start a 14-day trial and import one Raindrop HTML export — you can run both libraries in parallel until you're sure.
