Wire vs Browserbase: why the layer your agent uses matters

Browserbase launched Browse.sh on June 8, 2026 - a catalog of reusable browser skills for AI agents. The pitch: agents rediscover the same websites from scratch on every run. A Craigslist search that costs $0.22 per run drops to $0.12 after a Browse.sh skill is loaded - a 45% reduction that compounds across thousands of production runs. (Browserbase Browse.sh launch 2026)

Wire's cost for the same call: $0.001.

That gap isn't an optimization difference. It's an architecture difference.

The problem both products are solving

Browser agents have a memory problem. Every time your agent needs to search Amazon or extract a Zillow listing, it starts from zero:

1. Spin up a Chromium instance
2. Load the full page - DOM, scripts, tracking pixels, ads
3. Screenshot or snapshot the rendered output
4. Pass the mess to an LLM: "find the product price"
5. The LLM reasons about the layout, locates the value, returns it
6. Repeat for every follow-up action

The cost is real. The latency is real. And if the site updates its layout, the whole thing breaks.

Browse.sh's answer: give agents a SKILL.md file per site with pre-loaded procedural knowledge - exact workflow steps, CSS selectors, undocumented API endpoints, site-specific gotchas. The agent still runs a browser, but it doesn't rediscover anything from scratch. Token spend drops. Reliability improves.

Wire's answer: don't run a browser at all.

What Browse.sh is

Browse.sh launched with 100 curated skills. Each skill is a markdown file plus optional helper scripts:

• Exact workflow steps for a specific task on a specific site
• CSS selectors and API endpoint paths
• Site-specific details agents would otherwise learn through trial and error (example: Craigslist's item[0] is an offset, not a posting ID - you need data.decode.minPostingId to avoid 404 errors)
• Fallback strategies when the primary path fails

Install and use via the Browse CLI:

npm i -g browse
browse skills add zillow.com/extract-listings

Then in your agent prompt: "Use /extract-listings to find apartments under $3,000 in SF with 2+ bedrooms."

The skill provides site knowledge. The agent provides reasoning. Under the hood, Stagehand - Browserbase's open-source browser SDK with 22,000+ GitHub stars and 700,000 weekly downloads - is still driving a real Chromium instance and calling an LLM on every run. Browse.sh adds a memory layer on top of the browser. It doesn't remove the browser from the execution path.

That difference shows up in cost and latency at scale.

How Wire works

Most high-traffic websites - Amazon, GitHub, Zillow, Reddit, Bloomberg, and 900+ others - already have internal APIs their own frontends use. When the Amazon product page loads, your browser isn't rendering from scratch: it's receiving structured JSON from backend services and rendering it client-side.

Wire identified those background API calls, reverse-engineered the request signatures, and wrapped them as maintained REST endpoints. Your agent calls Wire; Wire calls the site's real backend API directly - no browser, no screenshot, no LLM in the execution path.

curl -X POST https://api.openwire.sh/v1/wire/task \
  -H "X-API-Key: $ANAKIN_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "action_id": "amazon.search_products",
    "params": {
      "query": "mechanical keyboard",
      "limit": 10
    }
  }'

Response:

{
  "job_id": "job_01j5x...",
  "status": "queued",
  "poll": "/v1/wire/jobs/job_01j5x..."
}

Poll for the result:

curl https://api.openwire.sh/v1/wire/jobs/job_01j5x... \
  -H "X-API-Key: $ANAKIN_API_KEY" 

{
  "status": "completed",
  "latency_ms": 178,
  "credits": 2,
  "result": {
    "items": [
      {
        "title": "Keychron K2 Pro",
        "price": 99.99,
        "rating": 4.6,
        "reviews": 2340,
        "asin": "B0BJFDQ5KK"
      }
    ]
  }
}

Structured JSON. No HTML. No markdown-converted page dump. Zero tokens burned parsing a layout.

Wire's catalog covers 904 sites across 30+ categories - Finance, Marketplace, Research, Shopping, Government, Travel, Developer Tools, and more - with 4,918 discrete actions. New sites ship within days of a request.

Auth and credentials

Both products handle authentication. The approaches differ.

Browserbase offers Verified sessions - purpose-built Chromium instances with real fingerprints that bot-protection partners (including Cloudflare) recognize as legitimate. Their Web Bot Auth integration with Cloudflare Signed Agents means your browser agent gets allow-listed, not blocked. For login-gated workflows where you need a real session cookie, Browserbase's identity stack is built for it.

Wire uses a named identity model. Save credentials once as a named identity (e.g., id_personal), then pass the identity reference in your task request. Wire resolves the credential inside an AES-256 encrypted vault at runtime - the secret never crosses the API boundary and is never returned by responses. For data extraction tasks on Wire's catalog, the agent never handles raw credentials.

Wire also integrates with 1Password as a native identity source. Connect your 1Password account, bind a vault item to a Wire identity, and Wire handles session refresh automatically via 1Password when credentials expire - no manual re-login. The POST /v1/wire/login endpoint supports both manual password and 1Password auth in a single call. When a session goes stale, POST /v1/wire/credentials/verify re-authenticates via 1Password without surfacing the credential to your code.

Wire via MCP

Wire ships inside the Anakin MCP server. One configuration line and your agent gets a native wire_action tool that covers every site in the catalog - no SDK, no wrapper code. Available in Claude, Cursor, Cline, Windsurf, Zed, and any MCP-compatible client. See the Wire MCP quickstart to set it up.

Browse.sh integrates via the Browse CLI, which works with the same AI coding tools. Both products are designed for the agent-native path. The difference is what runs underneath when the action fires.

Head-to-head comparison

Where Browserbase and Browse.sh make sense

Wire can't do everything. Browser automation is the right tool for:

Interactive workflows - logging into accounts, navigating multi-step forms, submitting data. Wire reads structured data; it doesn't drive UI interactions.

Sites outside Wire's catalog - Wire covers 904 sites. Everything else needs a browser. Browse.sh makes those browser calls cheaper and more reliable by pre-loading site knowledge so agents don't pay the rediscovery cost on every run.

Visual and dynamic tasks - CAPTCHA handling, JS-heavy SPAs without stable backend APIs, tasks that require seeing a rendered layout. Browserbase's Verified sessions handle these, with the Cloudflare Signed Agents partnership providing real browser identity rather than evasion.

Stagehand is the right tool for this class of work. Browse.sh reduces cost and improves reliability for repeat browser workflows. Both work well for interactive automation on sites outside Wire's catalog.

Where Wire makes sense

For data extraction across covered sites, Wire's structural advantage compounds quickly:

High-volume pipelines - calling Amazon 10,000 times a day at $0.001 vs $0.12 is a $1,190/day difference. At production scale, the economics are hard to ignore.

Latency-sensitive workflows - <200ms end-to-end means Wire can run synchronously in pipelines where browser automation would require async queuing infrastructure.

Clean context windows - every Wire response is structured JSON. No tokens burned parsing page layouts. Models downstream see clean data, not page dumps.

Reliability - Wire maintains its integrations. When Amazon updates its internal API contract, Wire's team updates the endpoint. Browse.sh skills track CSS selectors and rendered layouts, which change more often and require manual skill updates when they do. Network-layer extraction follows a stable API contract; selector-based skills follow a rendered surface.

Check if your site is covered

curl "https://api.openwire.sh/v1/wire/search?q=your-site" \
  -H "X-API-Key: $ANAKIN_API_KEY" 

If your target isn't listed, you can request an action from the catalog page. Most ship within days.

The structural difference

Browse.sh is Browserbase's answer to agent amnesia - a sensible solution to a real problem. Pre-load site knowledge so agents don't pay the rediscovery cost on every call. It cuts browser agent costs by 45% and makes skills auditable: plain markdown that humans can read and modify.

Wire's position is that for most data extraction use cases on most popular sites, the browser was never the right tool. The background APIs are already there. Wire exposes them directly.

Browse.sh made browser automation smarter and cheaper. Wire skips the browser and goes to the source.

For anything on Wire's catalog, use Wire. For interactive workflows, sites Wire doesn't cover, and tasks that genuinely need a browser, Browserbase and Browse.sh are the right path.
