## Browserless

Browserless gives developers a browser that already works in production instead of one that crashes, leaks memory, or gets blocked. Rather than running your own fleet of Chrome processes, you connect with a few lines of code over the WebSocket endpoint using Puppeteer or Playwright, or call task-specific REST endpoints for scraping, screenshots, PDFs, and downloads. The platform handles Chrome version upgrades, auto-scaling through traffic spikes, retries, and session queues so your automation code stays unchanged.

Its modern focus is AI agents. A built-in MCP server exposes search, scrape, and crawl tools that Claude, Cursor, or any MCP client can call directly, while Authenticated Profiles let an agent log in once and stay signed in across runs instead of hitting login walls or hard-coding credentials. Stealth fingerprints, CAPTCHA solving, and residential/datacenter proxies are included so agents that work in a demo also work against anti-bot-heavy production sites.

You can run Browserless as a fully managed cloud, a managed private cloud, or on your own hardware, using the same API in every case. The free tier covers 1,000 units per month with two concurrent browsers and no credit card; paid plans and enterprise agreements add concurrency, dedicated workers, SLAs, and compliance coverage such as SOC 2 Type II and HIPAA BAAs.

**Pricing & Plans:** Freemium: a free plan includes about 1,000 units per month with 2 concurrent browsers and no credit card. Paid plans scale units and concurrency, and self-hosted/enterprise options are quoted on request.

- **Puppeteer & Playwright endpoints:** Swap launch() for connect() and point your existing Puppeteer or Playwright scripts at a managed cloud browser — no rewrite required.
- **MCP server & browser agent:** Give MCP clients like Claude or Cursor ready-made search, scrape, and crawl tools, or run Browserless's own stateful agent for multi-step tasks.
- **Stealth, CAPTCHA & proxies:** Automatic anti-bot bypass, built-in CAPTCHA solving, and residential or datacenter proxy rotation to get through blocked targets.
- **Authenticated Profiles:** Log in one time and reuse the session across every run, so agents start signed in without credentials baked into your code.
- **Screenshot, PDF & debug APIs:** Generate pixel-perfect screenshots and PDFs from any URL, with a live debugger, request metrics, and worker health in the dashboard.

**Strengths:** One-line migration from self-hosted Puppeteer/Playwright to managed browsers; Built-in stealth, CAPTCHA solving, and proxies remove the hardest scraping work; Same API across cloud, managed cloud, and self-hosted deployments; Strong fit for AI agents via MCP server and persistent authenticated sessions

**Limitations:** Concurrency and unit quotas mean heavy scrapers can hit plan limits quickly; Pricing scales with usage, so high-volume workloads need cost planning; Advanced enterprise controls like dedicated GPUs and region pinning require sales contact

## StealthWriter

StealthWriter is built around two steps: scan and rewrite. The detector highlights sentences that still read as AI-written, and the humanizer then rewrites the text to smooth those passages out. Because you can run the detector again afterwards, it works as an iterative loop rather than a one-shot button, which makes it more practical for longer articles where only a few paragraphs sound robotic.

The tool targets people who draft with large language models but publish under their own name: bloggers, marketers, copywriters and researchers. Output can be tuned by rewriting level and, at the sentence level, by picking from alternative phrasings. Processing is quick — typically a matter of seconds — and the free tier with 10 daily humanizations and 1,000 words per input is enough to test whether the tone matches your writing style. Paid plans raise both the daily allowance and the maximum input length, which matters if you humanize long-form content regularly.

StealthWriter is a service of AiVantage LLC. On privacy, the company states that text submitted for humanizing or scanning is not stored after processing, not shared with third parties and not used for training. It is best treated as a drafting and polishing assistant: it improves how naturally AI-assisted text reads, but you should still review facts, claims and citations yourself before publishing.

**Pricing & Plans:** Freemium. The free plan costs $0 and includes 10 humanizations and 10 AI scans per day with up to 1,000 words per input. Paid tiers are Starter at $20/month (50/day), Plus at $50/month (150/day), Pro at $100/month (350/day) and Scale at $400/month (2,000/day), each allowing 5,000 words per input, with discounts for annual billing.

- **AI text humanizer:** Rewrites AI-generated drafts with natural phrasing, rhythm and flow, and lets you pick light, medium or aggressive rewriting depending on how much change you want.
- **Built-in AI detector:** Scan text before and after humanizing to see which sentences still look machine-written, with colour-coded sentence-by-sentence highlights.
- **Alternative rewrites per sentence:** Click any sentence to see alternative rewrite options and fine-tune the output until it matches your own voice.
- **Fast batch processing:** Returns humanized text in seconds, with word limits per input ranging from 1,000 words on the free plan up to 5,000 words on paid tiers.
- **Volume-friendly quotas:** Daily allowances scale with your plan, from 10 humanizations a day on the free tier up to 2,000 a day on the Scale plan, for high-volume content workflows.

**Strengths:** Free plan lets you test the humanizer and detector at no cost; Detector and humanizer in one workflow makes quality checking easy; Sentence-level alternative rewrites give fine control over tone; Three rewrite strengths suit different content types

**Limitations:** Monthly quotas are metered per day, so bursty heavy users may hit limits; Humanised text still needs a human read-through for factual accuracy; Result quality varies by language and by how obviously AI-written the source is; No built-in grammar or plagiarism checker beyond the AI detector
