Browserless alternatives: How to pick by job

The right pick among Browserless alternatives depends on why you are leaving. Choose a hosted CDP browser when anti-detection upkeep or the billing unit is the problem, self-hosted Playwright or Puppeteer when you need isolation or a fixed load, Selenium Grid for cross-browser testing, and a scraping API when you only need page content.

You look for Browserless alternatives when the bill scales with something you didn’t expect, when you now patch around bot blocks yourself, or when a session cap or self-hosting rule gets in the way.

After reading, you can sort the options by job, change the connection line in Playwright or Puppeteer, model your own bill and pick one. We sell one of these options, Wayfern, and we list its downsides next to everyone else’s.

Key Takeaways

• Moving between CDP endpoints changes one line in Playwright or Puppeteer, PandaStack notes, but only when the target exposes CDP.
• For bursty loads, per-session minimums and concurrency caps set your cost more than the headline rate, Sliplane’s comparison says.
• On Wayfern, 1,000 five-second pages bill 133.3 credits instead of 11.1, because each page carries a 60-second minimum.
• Moving to a scraping API means rewriting the calling code, because it exposes no WebSocket endpoint to connect to.

What counts as a Browserless alternative?

A Browserless alternative is any tool that does the same job for your workload, and for a hosted browser driven from code that means a service with a CDP WebSocket endpoint. Scraping APIs, Selenium Grid and serverless rendering solve adjacent jobs. They replace Browserless only when you can change how your code talks to the browser.

Browserless exposes a WebSocket endpoint that existing Puppeteer or Playwright code connects to with one line changed, as PandaStack’s roundup describes it. A direct replacement keeps that contract.

Browserless alternatives split into six classes, and each one changes your script differently:

• Hosted CDP browsers (Browserbase, Hyperbrowser, Steel hosted, Wayfern): keep the script, swap the WebSocket URL and token.
• Open-source or self-hosted browser APIs (Steel’s repository, Browserless’s own self-hosting option): keep the script, point it at your own host, and read the license terms in each repository before you ship.
• Serverless rendering (Cloudflare Browser Rendering): port the script to the platform’s runtime and the API subset it supports.
• Scraping APIs of the request-and-response type (ScrapingBee, Firecrawl): rewrite the calling code, because you send a URL and receive content instead of driving a page.
• Self-run Playwright or Puppeteer: keep the script and launch the browser yourself, which makes you the owner of upgrades, crashes and proxies.
• Selenium Grid: rewrite to WebDriver if your code is CDP-based.

Among Browserless alternatives, Selenium Grid does a different job from the rest. Selenium’s Grid documentation says the Grid works by “routing commands sent by the client to remote browser instances”. A hub routes WebDriver sessions to nodes that each run a browser, so it works as a test farm with no CDP URL to drop in.

Our comparison of Browserless alternatives covers the hosted CDP class in more detail.

How do you switch to Browserless alternatives in Playwright and Puppeteer?

Switching endpoints in Playwright or Puppeteer means replacing the WebSocket URL you pass to connectOverCDP() or connect(), provided the new target exposes CDP over WebSocket. In Playwright, only the first argument changes:

import { chromium } from "playwright";

// Before: Browserless-style URL, token as a query parameter
// const browser = await chromium.connectOverCDP("wss://BROWSERLESS_HOST?token=BROWSERLESS_TOKEN");

// After: Wayfern
const browser = await chromium.connectOverCDP(
  "wss://api.wayfern.com/ws?token=LINK_TOKEN&country=US",
  { timeout: 90_000 },
);
const page = await browser.contexts()[0].newPage();
await page.goto("https://example.com");

Puppeteer follows the same pattern:

import puppeteer from "puppeteer-core";

// Before: browserWSEndpoint: "wss://BROWSERLESS_HOST?token=BROWSERLESS_TOKEN"
const browser = await puppeteer.connect({
  browserWSEndpoint: "wss://api.wayfern.com/ws?token=LINK_TOKEN&country=US",
});

Everything after the connect call stays as it was. Then work through these steps:

1. Raise the connect timeout to 90 seconds or more. A Wayfern cold start runs longer than Playwright’s default connect timeout in many setups.
2. Delete launch options. Arguments you passed to launch() or packed into the old URL have no effect on a browser you attach to.
3. Strip vendor query parameters. Wayfern reads token, country, region, city, session, proxy, width and height. Unknown location codes are not ignored: Wayfern’s anti-detect sessions guide states that “an unknown location is refused with close code 4007 instead of falling back to the wrong place.”
4. Remove session lifecycle calls. Opening the socket starts the session, so there is no create-session REST call to keep.
5. Reuse the existing context. Call browser.contexts()[0] instead of newContext(), and confirm your script doesn’t depend on fresh contexts for isolation.

Playwright’s own docs warn that a CDP attach is not equivalent to its native protocol: “This connection is significantly lower fidelity than the Playwright protocol connection via browserType.connect().” Run your suite once before you cut over, especially if it uses advanced features.

How does pricing differ across Browserless alternatives?

Browserless alternatives differ in what they meter: a unit, a credit, an open-page hour, or a server you rent.

	Browserless	Wayfern	Self-hosted
Billing unit	Units	Credits	Server fee
Cost grows with	Concurrency, session length	Open-page seconds, residential GB	Server count
Concurrency set by	Plan tier	Plan (20 to 400 pages)	Your hardware

Sliplane’s comparison describes Browserless as billed in units, with costs that “can climb fast when you need more concurrency or longer sessions.”

Browserbase, Steel, Hyperbrowser and Cloudflare Browser Rendering each publish their own meters. From each pricing page, copy the unit, the per-session minimum, the concurrency cap and the separately metered items.

Wayfern’s pricing page lists browser time at 8 credits per open-page hour, metered per second with a 60-second minimum per page, at a $0.0125 list rate per credit.

According to Wayfern’s limits docs, plans cap concurrency at 20 pages open at once on Developer, 100 on Business and 400 on Scale.

If you open 1,000 pages and each needs 5 seconds, the bill works out like this:

• Per-second billing alone: 1,000 × 5 s = 5,000 s, or 1.39 hours × 8 = 11.1 credits.
• With the minimum: each page bills 60 s, so 8 ÷ 60 = 0.133 credits per page, 133.3 credits in total, about $1.67.
• One page held open 2 hours: 16 credits, about $0.20. The minimum never applies.

Short bursts pay for 12 times the time they use. Long sessions pay for what they hold. Datacenter egress is free, while residential bandwidth is 320 credits per GB.

The pricing page also states: “Hard stop at zero. Nothing runs on credit you did not buy. Auto top-up is off until you turn it on.” At zero, calls are refused and open sessions close.

The same balance pays for Search API pages (2 credits per provider results page) and captcha solving (1 credit per successful solve). The MCP server uses the same wf_ token model. If you now pay a browser vendor, a SERP API and a captcha solver separately, those three bills become one balance.

Each of these Browserless alternatives suits a different load:

• Browserless suits teams whose workload already fits its units and tiers. Check whether short bursts cost less there than under a 60-second minimum.
• Wayfern suits long sessions and workloads that combine browser, search and captcha. It has no free tier.
• Self-hosting suits fixed loads where a flat server fee beats any meter.

What does anti-detection mean for hosted Browserless alternatives?

Anti-detection for a hosted browser means keeping the signals a site compares across requests consistent with one another, so the session reads as a single visitor. A site rarely blocks on one odd value; the usual trigger is two values that disagree.

A few checks cover most of the mechanics for hosted Browserless alternatives:

• Browser identity: the fingerprint is either applied inside the browser build or injected by scripts into each page you load.
• Exit IP and cookie state: a cookie issued to one IP and replayed from another is an easy signal for a site to read, according to Wayfern’s anti-detect sessions page.

In a login flow, passing the same session value on every connection keeps the cookie and the exit together:

const browser = await chromium.connectOverCDP(
  "wss://api.wayfern.com/ws?token=LINK_TOKEN&country=US&region=CA&session=run42&width=1366&height=768",
);

The term “anti-detect browser” covers two different products. Desktop profile managers are driven by a person and keep many long-lived profiles with per-vector switches. Programmable hosted browsers are driven by code over CDP, and Wayfern is this second kind.

Buy a profile manager when a person is the operator, and a programmable hosted browser when your scripts are. Our buyer’s guide to anti-detect browsers compares both kinds on fingerprint control and state persistence.

If you maintain your own patches, proxies and driver versions, a hosted browser replaces that upkeep. If you need hand-managed identities, it does not.

To test it, mint a link token and run the snippet against a page you own.

What is the downside of each Browserless alternative?

Every Browserless alternative costs you something specific: a vendor-defined session model, upgrade work, API lock-in, or the loss of a CDP endpoint.

1. Hosted CDP browsers (Browserbase, Hyperbrowser, Steel hosted, Wayfern). The vendor defines and meters the session model, so session length, concurrency caps and self-hosting rules are theirs. This class fits best when anti-detection upkeep or a bursty load is why you left. Our Browserbase alternatives comparison covers where Browserbase remains the stronger cloud browser platform.

2. Open-source or self-hosted browser APIs (Browserless itself, Steel’s open-source release). You own upgrades, scaling and proxy wiring. This class fits a fixed, predictable load, or isolation rules that keep browsers on your network. Sliplane describes self-hosted Browserless as having “no per-unit fees, no session limits, and no shared resources.”

3. Cloudflare Browser Rendering. You build against Cloudflare’s supported API and live within the session and concurrency limits its docs list. It fits when the rest of your stack already runs on Cloudflare and your jobs are short.

4. Scraping APIs (ScrapingBee, Zyte, Bright Data, Firecrawl). There’s no CDP endpoint, so multi-step logged-in flows don’t fit. They suit jobs that only need page content, such as markdown, HTML or JSON for a list of URLs.

5. Self-run Playwright or Puppeteer. You maintain the pool, the driver versions and the proxies. PandaStack lists what that means in practice: “dealing with zombie processes, memory that only goes up, crashed tabs that hold a slot forever.” It fits when you want full control over a small, steady workload.

6. Selenium Grid. It runs WebDriver sessions with no CDP WebSocket URL, so connectOverCDP() and puppeteer.connect() code can’t point at it. It fits when you need Firefox, WebKit or cross-browser QA.

Match the reason you’re leaving to the list. A billing unit that doesn’t fit your load points to options 1 or 2. Anti-detection upkeep points to option 1, and isolation or self-hosting requirements point to options 2 or 5. A job that only reads pages points to option 4, and cross-browser testing points to option 6.

What are Wayfern’s limits, and when should you pick something else?

Wayfern has several limits, and for each one another tool does the job better.

• Session state: you save and restore cookies and storage in your own code.
• Fingerprint control: there are no per-vector fingerprint switches. If hand-managing identities is the job, a desktop profile manager such as Multilogin does it, as our Multilogin comparison explains.
• Browser coverage: a CDP endpoint speaks Chromium’s protocol only, so use Selenium Grid for cross-browser QA.
• Mobile: there’s no mobile emulation.
• Trial: there’s no free tier or trial.
• Cold start: a session takes about 45 to 50 seconds to start, longer with a residential exit.

For a fixed nightly load, run Playwright or Puppeteer on your own servers, where a steady job keeps the machines busy and the startup delay doesn’t recur per session.

If you only need page content, a scraping API returns the page without a browser session for you to manage. If Browserless’s session model matches your load, compare both in our Browserless alternatives page before moving.

Which of the Browserless alternatives fits your job?

Your job decides which Browserless alternative fits: match the workload to an option class, then check one limit before you pay.

Job	Option class	Verify before committing
Bursty scraping	Hosted CDP browser	Per-session minimum and concurrency cap
Long agent sessions	Hosted CDP browser	Session length limit and hard stop behavior
Cross-browser QA	Selenium Grid or self-run Playwright	Firefox and WebKit support
Fixed nightly crawl	Self-hosted	Server cost against metered cost
Content-only extraction	Scraping API	Output format and what is billed on failure

A hosted CDP browser bills by a unit you don’t control. A short burst can cost a full minimum per session, and a concurrency cap queues the rest. Long sessions end at a limit, and the browser closes whatever was mid-task. Wayfern sits in this class, so the same checks apply to it.

Selenium Grid or self-run Playwright is the better pick when Firefox or WebKit matters, because a CDP endpoint speaks Chromium’s protocol only. You then run, patch and scale the fleet yourself.

Among Browserless alternatives, self-hosting wins on a fixed load. A server costs the same busy or idle, so it beats metered billing when it stays busy, and you own upgrades, crashes and proxy wiring.

A scraping API wins when you only need page content. Logins and multi-step flows on top of one mean rewriting the calling code.

Frequently asked questions

What is the best Browserless alternative?

The best Browserless alternative depends on why you’re leaving. Pick a hosted CDP browser for bursty or protected targets, self-hosted Playwright for fixed loads, Selenium Grid for Firefox or WebKit, and a scraping API for page content only. Check the billing unit and session limits first.

Can I switch from Browserless by changing one line?

Usually, if the new service exposes a CDP WebSocket. As PandaStack notes, you replace the URL in Playwright’s connectOverCDP() or Puppeteer’s connect(). Playwright’s docs call that connection lower fidelity than its own protocol, so retest advanced features.

Is there a free Browserless alternative?

Self-hosted Playwright or Puppeteer needs no vendor plan, but you run the servers, upgrades and proxies. Read each license before shipping it, and check each hosted vendor’s pricing page.

Do I need an anti-detect browser or a hosted browser?

Choose by who operates it. A desktop profile manager suits a person managing many long-lived profiles by hand (see our Multilogin comparison). A programmable hosted browser suits code driving sessions over CDP, which fits scheduled scraping and agents.

When is a scraping API better than a hosted browser?

A scraping API is better when you only need page content. It returns markdown, HTML or JSON per request with no CDP endpoint, so there’s no session to manage. Logins, multi-step forms and waiting for elements need a driven browser. Our web scraping buyer’s guide compares both.

Next steps for testing Browserless alternatives

Today, before you compare Browserless alternatives, write down why you’re leaving and the job the browser has to do. Match both against the decision table, and drop every option class that can’t give you a CDP endpoint for that job.

This week, change the one connection line in connectOverCDP() or connect() to point at a candidate endpoint, then run one real flow end to end. Set the connect timeout high enough to allow for a cold start.

Before committing budget, compare the billing unit, the per-session minimum and the concurrency cap against your actual load. Your own targets are the only measurement that applies to your workload.

To run that test on Wayfern, buy a small credit pack or the Developer plan, then point your existing script at its CDP endpoint. Current plans and packs are on the Wayfern pricing page.
