Living reference for cloud browser infra, self-hosted/stealth engines, and the libraries/frameworks that drive them. Curated for agentic web automation at scale (e.g. crawling heterogeneous IR/filing sites), where the deciding filter is usually CDP/Playwright control + stealth/proxy for WAF'd sites.

- CDP / Playwright — does it expose a Chrome DevTools Protocol endpoint (raw
wss://) or a Playwright/Puppeteer-compatible connection? This is the must-have for agentic loops that reason over the DOM (find a link, read selectors, build a crawl manifest) rather than over pixels. Tools that only return final HTML (scrape APIs) or only drive via vision/mouse can't host an interactive DOM agent unchanged. - Self-host — can you run it on your own infra (e.g. GKE) with no per-session fee?
- Stealth / Proxy / CAPTCHA — built-in anti-detection, residential proxy routing, and CAPTCHA solving (the lever for the WAF-blocked long tail: Cloudflare / Akamai / Incapsula).
- Maturity — rough production-readiness, not a benchmark.
- ✅ = supported ·
⚠️ = partial/caveat · ❌ = no/not applicable · ❓ = unverified
⚠️ Claims discipline: performance numbers (e.g. "11x faster") are vendor/marketing claims unless a benchmark link is given. Architecture facts (CDP support, control model) are verified from each vendor's API reference / docs, not their landing page — landing pages oversell. Re-verify before betting a production run on any single tool.
Direct Browserbase-class options. These host the browser; you keep programmatic control.
| Tool | CDP / Playwright | Self-host | Stealth / Proxy / CAPTCHA | Entry price | Maturity | Notes |
|---|---|---|---|---|---|---|
| Browserbase | ✅ CDP + Stagehand SDK | ❌ | ✅ (Stealth Mode, custom Chromium) | $39/mo (200 hrs, 3 concurrent); $99/mo (500 hrs, 50 concurrent) | Established — 50M sessions/2025, $40M Series B @ $300M | Market leader; Stagehand adds act()/extract()/observe() AI primitives. Usage-based pricing. |
| Steel.dev | ✅ CDP/Playwright | ✅ OSS, Apache-2.0 (Docker) | ✅ (cloud tier) | Cloud: free 100 hrs then $29/mo; self-host ~$5–15/mo infra | Established | Best self-host story. Run fleets on your own GKE, no per-session fee, full CDP. Batteries-included session API + UI. |
| Browserless | ✅ CDP/Playwright/Puppeteer/Selenium | ✅ (Docker, private deploy) | ✅ BrowserQL (strongest stealth: hidden-iframe/shadow-DOM verify clicks, CAPTCHA auto-solve) | ~$140/mo cloud; free 1k units; self-host available | Established | Best raw anti-bot engine + self-host. Good for the Cloudflare/Akamai tail. |
| Hyperbrowser (YC) | ✅ CDP/Playwright/Puppeteer + MCP | ❌ | ✅ Stealth + Ultra Stealth, fingerprint randomization, CAPTCHA | $30/mo (25 concurrent); $0.10/browser-hr + $10/GB proxy | Newer ("less proven") | Bursts to 10k+ concurrent. HyperAgent framework. LangChain/LlamaIndex/MCP native. |
| Anchor Browser | ✅ (CDP, computer-use flavored) | ❌ | ✅ stealthy Chromium fork + built-in VPN (no 3rd-party proxy) | $20 starter; $0.05/browser-hr + proxy; full-stealth tier $2,000/mo | Newer | Auth/identity handling focus; "plan deterministically, revert to AI at runtime." Full-stealth tier pricey. |
| Solari Browser | ✅ connectOverCDP(session.cdpEndpoint) + Puppeteer browserWSEndpoint; wire-protocol mode on patchright-core@1.59.3 |
❌ | ✅ stealth + residential proxy + CAPTCHA (opt-in) | Free; $20/mo Starter (20 concurrent, 200 hrs); Enterprise custom | Research preview | Control is DOM/CDP ("anything that works in Playwright works on Solari") despite landing page's "vision/keyboard/mouse" wording. Cheap; sub-second start. Maturity caveat. |
| Cloudflare Browser Rendering / Browser Run | ✅ CDP (Playwright/Puppeteer) + MCP client | ❌ | Usage-based on CF | Established (CF) | Serverless headless Chrome; integrates if you're already on Cloudflare. MCP support for Claude/Cursor. |
For maximum control + cost optimization at scale. You bring infra (and DevOps).
| Tool | CDP / Playwright | Stealth | Footprint / Lang | Stars / Status | Notes |
|---|---|---|---|---|---|
| Playwright (Microsoft) | ✅ native (CDP for Chromium; own protocol for FF/WebKit) | ❌ baseline (detectable) | Node/Python/Java/.NET | De-facto standard | The control layer everything else wraps. No stealth on its own. |
| Puppeteer (Google) | ✅ CDP (Chromium/Chrome) | ❌ baseline | Node | De-facto standard | Chrome-focused; puppeteer-extra-plugin-stealth adds patches. |
| Patchright | ✅ Playwright-compatible (drop-in) | ✅ stealth-patched Playwright runtime | Python/Node | Active | Stealth fork of Playwright. Note: Solari's wire-protocol mode pins patchright-core@1.59.3. |
| Camoufox (daijro) | ✅ Playwright-compatible | ✅ Firefox fork, C-level fingerprint spoofing (canvas/WebGL/screen/navigator), Playwright agent sandboxed | ~200 MB / C++ | ~8.8k★, active again | |
| nodriver / undetected-chromedriver | ✅ anti-detection | Python | Popular | Common stealth route for Selenium-based stacks. | |
| Lightpanda | ✅ CDP (Playwright/Puppeteer) + MCP | ❌ (proxy/header support, no fingerprint stealth) | ~9x less mem (claim) / Zig, V8 JS | ~30.7k★, beta | |
| Obscura (h4ckf0r0day) | ✅ CDP | ✅ stealth | ~30 MB (claim) / Rust, V8 | ~13.9k★, active | Real & maintained but no production track record found — fine for a spike, too green for a 48k run. |
These sit on top of an engine/infra. Different layer from §1–2.
| Tool | What it is | Notes |
|---|---|---|
| Stagehand (Browserbase) | Playwright + AI primitives (act/extract/observe) |
OSS SDK; bridges scripted Playwright and full agents. |
| browser-use | "Make websites accessible for AI agents" | Popular OSS agent loop; can drive CDP browsers (incl. self-hosted). |
| Skyvern | LLM + computer-vision automation (no brittle selectors) | OSS, Playwright-compatible, CAPTCHA + 2FA. Competes with a custom manifester agent, not with the infra. |
Vercel agent-browser |
Rust CLI giving agents browser control | agent-browser click @e2 style. |
Reach for these for the small % of sites blocked by Akamai/Cloudflare/Incapsula. Most expose a CDP-compatible "scraping browser" or a fetch-style unblocker. Fetch-only APIs (no CDP) can't host an interactive DOM agent — use as fallback fetchers, not as the manifester.
| Tool | CDP browser? | Notes / benchmark |
|---|---|---|
| Bright Data Scraping Browser / Web Unlocker | ✅ CDP-compatible | Enterprise unblocking on their proxy network. |
| Zyte API | Led Proxyway 2025 benchmark: 93.14% success on 15 heavily-protected sites. | |
| Oxylabs Web Unblocker / Scraper API | Agentic tooling (OxyCopilot); sub-second pre-indexed content for RAG. | |
| ScrapingBee | ❌ no CDP | 84.47% Proxyway 2025. Simple API; fallback fetcher only — not a manifester fit. |
Listed to prevent re-evaluation — these are terminal browsers for humans over SSH, not headless agent infra.
| Tool | Why it's here / why it's off-category |
|---|---|
| Carbonyl | Full Chromium in your terminal (~19k★) but last push 2024 (going stale). For human SSH use, not agent automation. |
| Browsh | Text-mode browser backed by headless Firefox; renders to terminal. Human tool. |
- Want self-host + no per-session fee + full CDP? → Steel (primary candidate).
- Need the strongest stealth for Cloudflare/Akamai sites? → Browserless / BrowserQL (self-host option) or a proxy-unblocker (Bright Data / Zyte) for the tail.
- Want cheap managed + fast start, OK with preview maturity? → Hyperbrowser or Solari (both CDP-compatible).
- Have a huge static-HTML majority and want to slash cost/latency? → spike Lightpanda as a fast-path engine, fall back to full Chromium for dynamic sites.
- Self-hosting stealth specifically? → Patchright (Playwright drop-in) > Camoufox (verify Akamai regression first).
- Avoid for DOM agents: fetch-only scrape APIs (ScrapingBee) and vision-only / terminal browsers.
At large scale, browser infra is often a minor line item vs LLM cost — optimize for coverage on protected sites and avoiding lock-in (favor CDP-standard + self-hostable) over squeezing per-session price.
- 2026-05-29 — Initial version. Verified CDP support for Solari (docs:
session.cdpEndpoint,connectOverCDP), Camoufox issue #555 (Akamai regression), GitHub stars/activity for Lightpanda/Camoufox/Obscura/Carbonyl. Confirmed "Solari Browser" is a real product (earlier dismissal retracted).
- Re-verify pricing + maturity quarterly; vendors change tiers often.
- When adding a tool: settle CDP support from its API reference / connection code, not the homepage.
- Mark every perf number as a claim unless paired with a benchmark link.
