GTOkiller is an exploitative poker solver built on Mass Data Analysis (MDA). While GTO solvers compute strategies against a perfect opponent that doesn't exist, GTOkiller solves against how your player pool actually plays, measured across millions of real hands, and shows you exactly which leak each deviation attacks and how much EV it extracts.

Key features: - Full-tree exploitation: the exploitative layer is applied to the entire game tree on every street simultaneously, not single-node nodelocking - 3-strategy view: GTO baseline, measured population frequencies, and the EV-maximizing exploit, side by side and fully auditable - Real pool data with visible sample sizes per node and a public methodology for showdown bias correction - AI Coach anchored to the actual numbers of each node, not a generic chatbot

Free plan available. Paid plans from โ‚ฌ39/month.

Possible disadvantages of PythonAnywhere

  • Limited Customization
    The pre-configured environment limits customization options, which may be a drawback for more advanced users who require specific configurations or installations.
  • Free Tier Limitations
    The free tier has significant limitations, including restricted CPU time and storage space, which can hinder more demanding applications.
  • Performance
    Shared plans might experience slower performance during peak times due to the shared nature of the infrastructure.
  • Lack of Root Access
    Users do not have root access to the underlying system, which can be a limitation for deploying certain types of applications or custom services.
  • Support Limitations
    While it offers community support and documentation, the level of professional support might not meet the needs of all users, especially those on lower-tier plans.
  • Limited Language Support
    Primarily focused on Python, which may not suit all projects, especially those requiring multi-language support.
  • Resource Constraints
    Lower-tier plans have stringent resource limits (CPU, RAM, storage), which can be restrictive for resource-intensive applications.

Questions & Answers

As answered by people managing GTOKiller and PythonAnywhere.

What makes your product unique?

GTOKiller's answer

GTOkiller is an exploitative solver, not a GTO solver. GTO solvers compute strategies against a theoretically perfect opponent that doesn't exist in real games. GTOkiller computes the strategy that maximizes EV against the way your player pool actually plays, measured with Mass Data Analysis across millions of real hands. The exploitative layer is applied to the entire game tree simultaneously, and every deviation is auditable: you see the GTO baseline, the real population frequencies, and the exploit side by side.

What's the story behind your product?

GTOKiller's answer

GTOkiller was built by a small team of poker players and engineers in Spain who kept running into the same wall: hours of solver study that real opponents simply didn't respect. If the pool doesn't play GTO, a strictly better strategy must exist. They built the engine to compute it: mass data analysis over millions of real hands, turned into full-tree exploitative strategies with every number visible.

Why should a person choose your product over its competitors?

GTOKiller's answer

Compared to GTO solvers (GTO Wizard, PioSOLVER, GTO+): they teach you to play against an opponent that doesn't exist. Their exploitative features rely on manual nodelocking, which is theoretical, biased by your own assumptions, and limited to one node at a time. GTOkiller applies real population data to the full tree automatically, at roughly half the price of GTO Wizard's top tier.

How would you describe the primary audience of your product?

GTOKiller's answer

Online cash game regulars at low and mid stakes (NL10 to NL200) who already study with solvers but feel their study doesn't translate into winrate, because their pools don't play anything close to GTO. Also MDA-oriented players who run population analysis by hand and want it automated and turned into complete strategies.

Which are the primary technologies used for building your product?

GTOKiller's answer

A proprietary solving engine and a Mass Data Analysis pipeline processing millions of hands per pool, served through a web app built on Next.js and Google Cloud.

Who are some of the biggest customers of your product?

GTOKiller's answer

Individual online cash game professionals and regulars across Europe, North America and Latin America

  • [Offer] I need someone to set up a webhook in my WordPress site and a Python server with listener + bot
    The website is already built. Each comment will have a reddit post URL, and the bot should leave a comment on that URL. We can use pythonanywhere.com for this to make it easiest. Source: about 3 years ago
  • Flask and web hosting
    If you are learning, use pythonanywhere.com as they specialize in python, and make setup easy. Only $5 a month. Start with a barebones flask app, get it to run, then follow a tutorial. Actually better to build the app locally, easier to test with IDE like Pycharm. Then upload to the net. Source: about 3 years ago
  • Redirecting client to my server via a external server
    Hello, I have a Minecraft server running on a Rpi with Paper. It works great and I use it to play with some of my friends. However, the server's public IP address often changes, meaning that I have to give my friends the new IP address daily. Being a programmer, I feel this could be automated. I don't want to buy a domain, so I want to try and setup a system where the server sends Its IP to my PythonAnywhere... Source: over 3 years ago
  • Question Gallery WebApp Django or Flask?
    Hosting wise, I would reccomend pythonanywhere.com, combined with either https://imagekit.io or https://cloudinary.com. Source: over 3 years ago
  • Cheap Heroku alternative for PHP MySQL app
    So what is the best alternative? I have one Plotly Dash app on pythonanywhere.com where I spend 6 bucks a month so I don't want to spend anymore than 5 dollars per month on the PHP + MySQL. Source: over 3 years ago
