About JavaScripting and GTOKiller

In their own words, as submitted to SaaSHub.

GTOKiller

No description of JavaScripting yet.

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...

Features and specs

What each product offers, as listed by its team.

JavaScripting 4 features
GTOKiller 6 features
  • Access to a Large Library
    JavaScripting provides access to a vast collection of JavaScript libraries, frameworks, and plugins, offering developers an extensive range of tools to enhance their projects.
  • Time-Saving
    Developers can save time by finding pre-existing solutions to common problems, allowing them to focus more on unique aspects of their applications.
  • Community Contributions
    The platform is supported by a community of developers who contribute and update libraries, ensuring you have access to the latest tools and trends.
  • Ease of Use
    JavaScripting is designed with a user-friendly interface that simplifies the process of searching and accessing JavaScript libraries.

Possible disadvantages

  • Quality Variability
    The quality of libraries can vary as they are community-contributed, meaning it can be challenging to find consistently high-quality or well-documented solutions.
  • Dependency Management
    Using multiple third-party libraries can lead to complex dependency management, potentially causing conflicts or bloat in your project.
  • Security Concerns
    Incorporating third-party libraries may introduce security vulnerabilities if libraries are not well-maintained or reviewed regularly.
  • Overlapping Functionality
    The large number of available libraries can lead to redundancy, with multiple libraries offering similar functionalities, which may confuse developers choosing the right tool.
  • 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 Population Data (MDA)
    Strategies computed from millions of real hands per pool, with visible sample sizes per node
  • Leak Detection
    Shows exactly which population leak each deviation attacks and how much EV it extracts, in bb/100
  • AI Coach
    Explanations anchored to the actual numbers of each node, not a generic chatbot
  • Transparent Methodology
    Public approach to showdown bias correction and sample filtering

Overall verdict

  • GTOKiller is a solid poker training tool for players looking to improve their game using GTO (Game Theory Optimal) principles in an affordable and accessible way. While not a replacement for full-scale solvers, it offers practical drills and quizzes that help build strong fundamentals.

Why this product is good

  • Provides GTO-based training drills that help players internalize optimal strategies
  • More affordable and beginner-friendly than heavyweight solvers like PioSolver or GTO+
  • Offers interactive quizzes and scenarios for practicing decision-making
  • Helps players recognize and correct common leaks in their game
  • Accessible interface that doesn't require deep technical solver knowledge

Recommended for

  • Beginner to intermediate poker players wanting to learn GTO concepts
  • Players on a budget who can't afford premium solver software
  • Anyone looking to practice preflop and postflop decisions through drills
  • Cash game and tournament players seeking to sharpen fundamentals
  • Recreational players wanting to move toward a more study-based approach

Questions & Answers

As answered by people managing JavaScripting and GTOKiller.

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.

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

How would you describe the primary audience of your product?

GTOKiller's answer:

Online cash game regulars at low and mid stakes (NL10 to NL100) who already study with solvers but feel their study doesn't translate into winrate, because their pools don't play anything close to GTO. Today the population data covers GG Poker NL10 to NL50; since leaks depend more on the stake than on the site, players at the same stakes on other sites use it as a close proxy.
