Hyperbrowser vs Anchor Browser
Both rent you a stealth Chrome in the cloud for your agents. Hyperbrowser adds short-lived Firecracker sandboxes for code and per-page web data APIs, while Anchor Browser stays a browser only and adds managed logins with MFA and hosted browser agents.
The companies and products
Hyperbrowser
Hyperbrowser calls itself the AI agents' gateway to the internet: cloud browsers, sandboxes, web data APIs and browser agents behind one API and one credit balance.
Its main product is a cloud Chrome session you drive with Playwright or Puppeteer, with stealth mode, residential proxies, CAPTCHA solving, saved profiles and recordings. Next to it Hyperbrowser sells Sandboxes, Firecracker VMs on Ubuntu 24.04 that live up to 24 hours, with memory snapshots, volumes and outbound rules, plus Fetch, Scrape and Search APIs and hosted browser agents. It is a browser and web data platform more than a general sandbox, so this page compares where it overlaps with bochka: agents that browse, and agents that run code.
Anchor Browser
Anchor Browser is cloud browser infrastructure for AI agents: managed Chromium sessions you control over CDP or a REST API, plus a hosted browser agent.
Anchor Browser is a different kind of product from bochka. Each session is a headful Chromium in its own VM that is erased when the session ends, and you drive it with Playwright or Puppeteer, with mouse and keyboard calls, or by sending a task in plain words to its hosted agent. It adds managed logins with MFA, residential proxies, stealth and CAPTCHA solving, and its own docs tell you to run your agent's code in a separate sandbox and connect to the browser over CDP.
Which use cases each one fits
For each use case, Battleships prices every sandbox provider on the same workload and sorts them from the cheapest monthly bill up. “20th cheapest of 367” means 19 of the other 366 providers run that workload, with every feature it needs, for less. “With limits” means the provider runs it but misses something, so it is listed after every full match. Open a use case for its whole ranking and what each provider misses.

Performance
There is no comparable measurement for either. Neither Hyperbrowser nor Anchor Browser publishes the CPU behind a browser session, and neither is in StarSling's CPU benchmark, where bochka scored 26.69 runs per second at 4 vCPU / 8 GB. Hyperbrowser publishes start times of under 50 ms for sandboxes and under 500 ms for a ready browser.
Node.js build-and-test loop at 4 vCPU / 8 GB, higher is better. Measured with the open hpc-sandbox-benchmarks suite. Hyperbrowser and Anchor Browser have no published run in this suite yet, so there is no like-for-like number to compare.
Pricing in five scenarios
Each bill is priced from the providers' public price lists by the open Battleships engine, with the cheapest plan that runs the scenario.
| Scenario | Hyperbrowser, a month | Anchor Browser, a month | bochka, a month |
|---|---|---|---|
| One coding agent, workdays 4 vCPU / 8 GB, 50 GB disk, 8 hours a day, 22 days a month, files kept between days | $16 · Free · with limits | $7 · Free · with limits | $20 · $20/mo |
| One agent that never stops 4 vCPU / 8 GB, 50 GB disk, running 24/7 all month | $73 · Free · with limits | $42 · Free · with limits | $26 · $20/mo |
| 50 agents in parallel 50 machines of 4 vCPU / 8 GB at once, 8-hour sessions, 1,100 sessions a month, Docker inside | $792 · Scale · with limits | $500 · Team · with limits | $317 · $20/mo × 3 seats |
| Sandboxes for your users 2 vCPU / 4 GB, 30,000 sessions of 10 minutes a month, up to 300 at once | $450 · Scale · with limits | $2,000 · Growth · with limits | $200 · $100/mo × 2 seats |
| 1,000 short jobs at once 2 vCPU / 4 GB, 1,000 at once, 3 minutes each, 200,000 jobs a month | $994 · Scale · with limits | $2,510 · Growth · with limits | $2,000 · $2000/mo · with limits |
Hyperbrowser: Everything spends one credit balance: browsers cost $0.10 a browser-hour plus $10 per GB of proxy data, and sandboxes $0.045 per vCPU-hour plus $0.015 per GiB-hour. Startup ($30) and Scale ($100) turn their fee into credits that reset each month.
Anchor Browser: Anchor bills $0.05 per browser-hour, counted to the nearest minute, plus $0.01 for each browser created. Plan fees (Starter $50, Team $500, Growth $2,000) become credits worth $1 each, and proxy traffic ($8 per GB) and AI task steps are extra.
Anchor Browser: Plans start at $20 a month, and the whole fee is usage credit spent per second while a sandbox runs. A stopped sandbox costs nothing and keeps its disk.
Limits in those scenarios
None of the five scenarios fits either one as written, because each asks for a general 4 vCPU / 8 GB machine and both price a browser session whose size is not published. Hyperbrowser's browsers keep no disk and neither offers Docker inside. Concurrency bites next: 100 browsers at once on Hyperbrowser's Scale and 200 on Anchor's Growth, so 300 sandboxes for your users and 1,000 short jobs at once need Enterprise on both. bochka fits four scenarios; at 1,000 short jobs at once its $2,000 plan queues the starts.
| Scenario | Hyperbrowser | Anchor Browser | bochka |
|---|---|---|---|
| One coding agent, workdays |
|
| None that bite |
| One agent that never stops |
|
| None that bite |
| 50 agents in parallel |
|
| None that bite |
| Sandboxes for your users |
|
| None that bite |
| 1,000 short jobs at once |

Which one should you use?
Use Hyperbrowser when
your agents mostly browse but also need short code sandboxes, warm starts from memory snapshots, or per-page fetch and search APIs, all on one credit balance.
- Sandboxes for code in the same account. For agents that browse and run some code: Firecracker sandboxes up to 32 vCPU sit next to the browsers on one credit balance.
- Warm starts from memory snapshots. For many short code runs: snapshot a running sandbox with its memory, then start new sandboxes from it as often as you like.
- Web data without a browser. For teams that just need page content: Fetch, Scrape and Search APIs are billed per page or query, so no browser has to run.
Use Anchor Browser when
your agents only need a browser and the hard part is the website: logins with MFA, city-level residential proxies, stealth, and sessions that run as long as you set.
- Logins handled for you. For agents working inside web apps with no API: managed identities with MFA stay logged in across sessions.
- Fine control over proxies. For scraping by place: residential proxies target country and city, with sticky IPs or your own proxy.
- Long sessions and your own cloud. For long browser jobs or strict hosting needs: sessions have no upper limit, and Enterprise runs in your own cloud or on-premise.
Where bochka fits
Hyperbrowser and Anchor Browser are browser companies, and both are good at getting a browser past bot checks. If what you are really running is agents that browse and also install, build, run Docker and keep their work, look at bochka: one full Linux VM per agent with Chromium and a desktop inside. You can also use both, with stealth pages on a cloud browser and everything else on bochka.
A real machine with Docker and root
Anchor has no shell and its docs send agent code to a separate sandbox, so you pay for and wire two services. Hyperbrowser's sandboxes do not document Docker inside, so docker compose and emulators have nowhere to run.
Work that survives the stop
A Hyperbrowser sandbox lives at most 24 hours and loses its disk on stop, and each Anchor session VM is erased. Volumes, profiles and snapshots keep some files, but installed tools start over. bochka saves the whole disk every minute.
Coding agents driven from outside, keys kept out
Hyperbrowser passes model keys in as environment variables and Anchor types secrets into the page, where a prompt-injected agent can reach them. bochka's credentials proxy keeps real keys outside, and you prompt and steer Claude Code or Codex through one API.
Use bochka when your agent does more than browse: it needs a shell, Docker, a desktop or a server next to Chromium, and it has to keep its work between runs. Compare it one to one: bochka vs Hyperbrowser and bochka vs Anchor Browser.
Questions people ask
Is Hyperbrowser cheaper than Anchor Browser?
Anchor's browser-hour is cheaper ($0.05 plus $0.01 per browser, against $0.10), so it costs less in most scenarios: 50 agents in parallel come to $792 on Hyperbrowser against $500 on Anchor. Sandboxes for your users flip it, $450 against $2,000, because Anchor needs Growth for that many browsers at once.
Which is faster, Hyperbrowser or Anchor Browser?
There is no comparable measurement. Neither publishes the CPU behind a browser session, and neither is in the CPU benchmark where bochka scored 26.69 runs per second. Hyperbrowser publishes under 500 ms for a ready browser.
Can Hyperbrowser or Anchor Browser run Docker?
Not in a documented way. Hyperbrowser uses Docker on your own machine to build a sandbox image, and its docs do not describe Docker inside a sandbox. Anchor has no shell at all; every bochka sandbox runs Docker, systemd and /dev/kvm.
How long can a session run?
Hyperbrowser browsers run up to 12 hours and its sandboxes up to 24 hours from VM start. Anchor sessions end after 180 minutes by default, but you can raise that with no upper limit. bochka has no session cap on paid plans and keeps the disk when you stop.
Which is better at getting past bot checks?
Both solve CAPTCHAs and offer stealth and residential proxies on paid plans. Anchor adds country and city targeting, sticky IPs and unique fingerprints on Enterprise, and Hyperbrowser adds ultra stealth on Enterprise. bochka runs Chromium on datacenter IPs and solves no CAPTCHAs.
Can I use Hyperbrowser or Anchor Browser from bochka?
Yes. An agent on a bochka sandbox can open either browser over CDP, and Anchor's docs describe exactly this setup. The code, files and tools stay on the bochka VM, and only the pages that need stealth go to the cloud browser.
Try bochka
Install the CLI, then run bochka new.
