Frequently Asked Questions
Find quick answers about CapSkip setup, features, licensing, and troubleshooting.
General
CapSkip is a desktop CAPTCHA solver that runs locally on your machine, VPS, or server. It supports image CAPTCHAs, Google reCAPTCHA, Cloudflare Turnstile, GeeTest v3, ALTCHA, CaptchaFox, Capy Puzzle, and Friendly Captcha, and can be integrated with third-party software using API emulation.
CapSkip supports:
- Image CAPTCHAs
- Google reCAPTCHA (v2, Invisible, v3, Enterprise)
- Cloudflare Turnstile
- GeeTest v3 slide puzzle
- ALTCHA proof of work
- CaptchaFox
- Capy Puzzle slide puzzle
- Friendly Captcha proof of work, both widget versions
Support for additional CAPTCHA types may be added over time.
Unlike traditional services, CapSkip runs locally and uses a flat-rate pricing model. There are no per-CAPTCHA charges, and performance depends on your hardware and setup.
No. CapSkip can be used through its interface, service emulator, or browser extension without coding. Developers can also integrate it using API endpoints.
Yes. CapSkip captcha solver works with almost any application by emulating the APIs of major CAPTCHA-solving services like 2Captcha, Anti-Captcha, and DeathByCaptcha. This allows CapSkip to plug into existing tools without modification. You can also use these same emulated APIs to integrate CapSkip into your own apps, scripts, and automation workflows.
For image CAPTCHA solving and for ALTCHA, Capy Puzzle, and Friendly Captcha v1, a standard Windows PC or VPS is more than sufficient and no high-end hardware is required. None of those types opens a browser, and ALTCHA and Friendly Captcha v1 are plain CPU work, so extra cores help far more than extra memory.
For reCAPTCHA, Cloudflare Turnstile, GeeTest, CaptchaFox, and Friendly Captcha v2 solving, real browser instances run in the background, so a Windows system with at least 32 GB of RAM is recommended for stable performance, especially when using higher thread settings.
ALTCHA is a proof of work CAPTCHA rather than a recognition one. There is no image to read and no audio to play. The target site issues a challenge, the client has to brute force the number that satisfies it, and that CPU cost is the whole defence.
Two things follow from that. A solve is deterministic, so there is no accuracy figure to quote: either the answer exists inside the range the site set, or the challenge was malformed. Solve time is set by the target site rather than by CapSkip, so most ALTCHA challenges finish in milliseconds, while a site that raises its maxnumber value can take noticeably longer.
ALTCHA also needs no browser and no proxy, which makes it the cheapest type CapSkip solves.
Friendly Captcha is the other proof of work type and works the same way, with one difference: the service sets the difficulty per request rather than the site setting it once, so solve time varies more between two challenges on the same site key.
Installation & Setup
Download the Windows application, run the installer, and log in using your account credentials after purchase or trial activation.
Set the correct Service Emulator, then use the configured IP:Port in your software. If needed, add the emulator domain using the Add to Hosts File option.
The Service Emulator allows CapSkip to mimic existing CAPTCHA-solving APIs.
Choose the emulator that matches the service your software expects, such as 2captcha.com.
Use:
- 127.0.0.1 if CapSkip runs on the same machine.
- Your VPS/server IP if running remotely.
Each Service Emulator sets its own port when you select it, from 8080 for 2Captcha to 8088 for NextCaptcha. Use that port in your software, or set another free port if it is taken.
Yes, if you want to use the original service domain (like 2captcha.com). This redirects requests to your local CapSkip instance.
Yes. You can run CapSkip on a VPS and connect to it using the server IP and port.
Browser Extension
Install it from the Chrome Web Store or Firefox Add-ons. Chromium browsers like Edge, Brave, and Opera also support Chrome extensions.
Common reasons:
- CapSkip is not running
- Wrong IP or port
- Service Emulator is not set to 2captcha.com
- CAPTCHA type is not enabled
- Missing proxy configuration
Right-click the CAPTCHA image and select Mark as CAPTCHA source, then right-click the input field and select Insert CAPTCHA answer here.

API & Integration
CapSkip exposes API endpoints that mimic existing CAPTCHA-solving services. Your software sends requests and receives results using the same structure.
CapSkip currently emulates:
- 2Captcha
- RuCaptcha
- Anti-Captcha
- CapMonster Cloud
- CapSolver
- DeathByCaptcha
- SolveCaptcha
- NextCaptcha
- Captchas.io
Only if API key validation is enabled. Otherwise, any key string will be accepted.
Any API key value will be accepted, which reduces security but simplifies setup.
Yes. They all work on the 2Captcha style endpoints (/in.php and /res.php) and on the Anti-Captcha style endpoints (/createTask and /getTaskResult), so an existing SDK usually needs nothing beyond the right task type.
The newer types use method=captchafox, method=capy and method=friendly_captcha on the form API, and CaptchaFoxTask, CapyTask and FriendlyCaptchaTask on createTask, each with a Proxyless variant. Capy Puzzle and Friendly Captcha also answer the DeathByCaptcha type codes, and Friendly Captcha the CapMonster custom task shape.
One detail is worth knowing for ALTCHA. DeathByCaptcha and CapSolver publish no ALTCHA task type of their own, so their clients have no spelling to send. CapSolver users can submit the Anti-Captcha AltchaTaskProxyless type instead, which CapSkip accepts.

Performance & Settings
It defines how many CAPTCHA tasks can be processed simultaneously.
The time CapSkip waits for a free processing slot when all threads are busy.
The maximum time allowed to solve a CAPTCHA before it is marked as failed.
The number of times CapSkip will retry solving a failed CAPTCHA.
Yes, for high-load environments. This improves performance by reducing interface overhead.
- Increase threads within system limits
- Use high-quality proxies
- Load only required models
- Disable unnecessary UI updates
Proxies
For image CAPTCHAs, ALTCHA, and Capy Puzzle, proxies are not required.
For reCAPTCHA, Cloudflare Turnstile, GeeTest, and CaptchaFox, proxies are required to avoid blocks.
ALTCHA is a partial exception worth knowing about: a proxy is used only when you ask CapSkip to fetch the challenge from a URL for you. A challenge you submit inline is solved locally and never touches the network.
Friendly Captcha sits between the two. It solves without a proxy, but the service raises the difficulty for an address it has already seen a lot of, so a proxy pool keeps throughput steady on a busy site key.
- HTTP/HTTPS
- SOCKS5
- SOCKS5 with DNS (SOCKS5h)
Low-quality or overused proxies often get blocked. Use reliable and rotating proxies.
It depends on your thread count. Ideally, use enough proxies to avoid reuse under load.
Use the Configure Proxies section and load them via list, URL, or file.
Licensing & Pricing
Each license is one flat monthly subscription with no setup fee: Bronze $35, Silver $60 or Gold $75 a month for one, two or three devices, with unlimited solving.
No. You pay the monthly price and nothing else: no setup fee, no per-solve charges and no overage invoice.
Access will be suspended. You can reactivate anytime by paying the subscription again.
Yes. Subscribe again whenever you like, with no setup fee.
No. You can use the trial to test the software before purchasing.
Yes. CapSkip offers a free trial with full app access for 3 days, including 500 CAPTCHA solves of any type, so you can test everything before choosing a license. No card is needed. Trial solving speed is lower than premium licenses. Start the Free Trial
All three licenses solve the same CAPTCHA types with the same accuracy. The difference is how many machines you can run CapSkip on: Bronze covers 1 device for $35 a month, Silver 2 devices for $30 each, and Gold 3 devices for $25 each. Each machine solves as fast as its own CPU and memory allow, so more machines run more threads at the same time: Silver solves twice as many CAPTCHAs at once as Bronze, and Gold three times as many.
Troubleshooting
Some antivirus programs may incorrectly flag CapSkip during installation or execution. This is a false positive, not an actual security threat.
This happens because CapSkip:
- runs advanced local processing and automation
- Frequent updates or unsigned binaries
- uses packaging methods common in high-performance desktop tools
These behaviors can sometimes trigger overly aggressive antivirus heuristics.
CapSkip does not contain malware, spyware, or any harmful code.
If your antivirus blocks the application, simply add CapSkip to your antivirus whitelist or exclusions list and run it again.
This is a common step for advanced automation and security-related software.
Check:
- CapSkip is running
- IP:Port is correct
- Service Emulator is set properly
- Proxies are configured for reCAPTCHA, Turnstile, GeeTest, and CaptchaFox
The CAPTCHA may be too difficult or not supported. You can request training for new types.
On ALTCHA there is one specific cause. CapSkip implements the PBKDF2 and SHA algorithms and refuses Argon2id and scrypt rather than attempting them, so a task using one of those returns this error in about a third of a second and shows Unsupported algorithm in the task list. ALTCHA recommends PBKDF2 as the default, so few sites are affected.
Friendly Captcha has a version trap of its own. Two different protocols ship under that one name and a sitekey does not say which one a site uses, so solving against the wrong one returns a well formed token that the site then rejects. Send the widget script URL along with the task and CapSkip reads the version off the build the site actually loads.
Possible causes:
- Too many threads
- Not enough proxies
- Slow system performance
Speed depends on your hardware, proxies, and configuration.
