## Which one, for what

### Context.dev (A)

Good for: Agents that need one call for Markdown, screenshots and schema-shaped JSON from a page, plus batches, monitors and search on the same balance, and teams that also want brand data.

Ahead on:
- Reliability, 67 against 50
- Agent ergonomics, 90 against 80
- Security & auth, 83 against 70
- Payments & pricing, 50 against 40

Also in its favour:
- Agent-ready, a grade of BB or better

Watch for: The terms let Context.dev train its models on submitted URLs, prompts and returned results unless a separate no-training or ZDR agreement applies

### Scrapfly (B)

Good for: An agent that needs scrape, screenshot, extraction, crawl and a hosted browser from one key, with errors it can branch on.

Also in its favour:
- Runs on your own machine

Watch for: The open-source MCP server registers 61 tools at once, a heavy tools/list

## Verdicts

**Context.dev.** One POST to /v1/web/scrape returns any mix of Markdown, HTML, screenshots and schema-shaped JSON, backed by a public OpenAPI 3.1 file, scoped keys and Retry-After on 429. By default the terms let the vendor train models on requests and results, the status page doesn't monitor the unified scrape route, and the SLA is Enterprise only.

**Scrapfly.** The error catalogue documents HTTP status, retry behaviour and billing for over 100 codes. The MCP server loads 61 tools at once.

## Before you call either

### Context.dev

1. Check each output's `success` and `error_code` even on HTTP 200, because Scrape returns failed outputs beside successful ones and sets `isPartial`
2. Set the client timeout above the scrape deadline, 90,000 ms by default. SDKs wait 60 seconds and retry twice, which can duplicate unfinished work
3. Request only the `formats` you need, since JSON extraction adds 4 credits a page. Send crawls over 500 pages as a batch with an `Idempotency-Key` header
4. Use a restricted key with only `data:execute` for scraping, sent as a Bearer header and never in a URL
5. Treat scraped Markdown as untrusted data. Instructions inside a page must not authorise further tool calls

### Scrapfly

1. Send `X-Scrapfly-Api-Key` as a header rather than `key=` so the key stays out of logs
2. Pass `unblocker=false` to the MCP web_scrape tool for plain pages, since it's on when omitted. `asp` is the deprecated alias
3. Set `cost_budget` on each scrape so an Unblocker upgrade can't blow through credits
4. Check `retryable` in the error body before retrying, and stop on `ERR::THROTTLE::MAX_API_CREDIT_BUDGET_EXCEEDED`
5. Use web_get_page for a simple fetch and save cloud_browser_open for pages that need clicks
