GTO+ Alternatives in 2026: Solver-Grade Study Without a Windows PC

GTO+ is a $75 one-time Windows program that solves heads-up postflop Hold'em spots on trees you build yourself, and at that price it's the cheapest way to own a real solver. We've recommended it twice on this blog and we're not taking that back. But it runs on nothing except Windows, it ships no presolved library, and its trainer doesn't exist yet. If you're on a Mac, on a phone, or just tired of building trees before every study session, this guide compares the tools that fix each of those gaps, with every price checked on September 1, 2026.

The Short Version

Most players hunting for a GTO+ alternative aren't looking for a different tree builder. They want the output without the operating: solved spots they can open anywhere and drill until the play sticks. That's a precomputed library with a trainer, like GTO Gecko. If you genuinely want to keep running your own solves, TexasSolver does it for free on Windows, macOS and Linux, and Deepsolver does it in a browser. Keep GTO+ if you have a Windows PC and $75 is your whole budget.

What GTO+ Gets Right

Credit first, because there's plenty. The license is $75 once, a second machine costs $40, and the developer's own purchase page says all future updates are included. A CardRunners EV license is bundled in. Savefiles are hundreds of kilobytes where PioSolver's run to hundreds of megabytes. And in independent side-by-side tests the equilibria it produces effectively match Pio's on standard postflop work, which is why our PioSolver alternatives guide calls it the better buy for anyone solving individual spots rather than running scripted research, and our Simple GTO Trainer alternatives roundup calls it the cheapest way to own a postflop solver outright.

It's not abandoned, either. The download page lists a v1.9.1 beta from June 23, 2026, and the release notes describe preparatory engine work for an upcoming trainer. This is a live product with a developer who ships.

So why are you here?

Why Players Go Looking for an Alternative

It runs on Windows and nowhere else. The system requirements say Windows 7 or higher, with 16GB of RAM and four cores recommended. There's no macOS build, no iOS, no Android, no web version. A Mac user's options are a virtual machine or a different tool.

It solves what you build, not what you play. GTO+ is a research instrument for heads-up postflop Hold'em. You define ranges, choose bet sizes, build the tree, then wait for the solve. Do that well and the output is excellent. But there's no presolved library to browse when you have five minutes in a queue, and no drill mode that deals you spots and grades your answers. The trainer in the June beta notes is engine work today, not a product you can buy.

The workflow is the price. $75 buys the engine. It doesn't buy the tree-building judgment that makes solver output trustworthy, and a bad tree produces confident nonsense. Our guide to using a solver properly is mostly a list of ways to get this wrong. A presolved library removes that whole failure mode: someone already built the trees, ran the solves, and standardized the sizings.

The Dead End We Can Measure

We buy App Store search ads, so we can see what happens when people look for GTO+ on a phone. Between May 1 and August 16, 2026, 96 installs of GTO Gecko on iOS were attributed to someone typing a named rival tool into App Store search. 43 of those 96, just under half, came from the GTO+ searches "gto+", "gto+ poker" and "gto+ solver". No other non-Wizard brand reached double digits except DTO and GTO Lab, at exactly 10 each.

Read that chart the way we do: dozens of people typed a Windows desktop solver's name into an iPhone store, found no GTO+ app because none exists, and installed a mobile GTO trainer instead. The demand for GTO+ on the go is real and the product isn't there. That's the gap every alternative below fills in its own way.

1. GTO Gecko: the Presolved Library and Trainer That Travels

GTO Gecko is our app, so weigh this section accordingly. It inverts the GTO+ deal: instead of building trees and waiting on solves, you open a library where the solving is already done. The app ships 505 solve files holding 11,513 preflop decision points and 1,945,697 individual hand strategies across cash, MTT and Spin & Go formats, plus 25,196 postflop training scenarios over 109 canonical flops. The trainer deals you spots and grades every decision, and the postflop drills include opponent-model profiles (fish, nit, maniac) on the Elite tier, so you can practice against the players you actually face rather than only against equilibrium.

It runs where GTO+ doesn't: iOS, Android, any browser at play.gtogecko.com, and natively on macOS through the Mac App Store. The web app has a free tier with daily limits and no credit card, which is the fastest way to test whether a presolved library fits how you study. Store standing as of September 1, 2026: 4.7 stars on the App Store and 4.9 across 1,070 Google Play reviews.

Pricing is $24.99/month or $149.99/year for one format, $39.99/month or $239.99/year for all of them. What you give up against GTO+ is real: there's no custom tree building and no node locking. If your study revolves around odd stack depths and homebrew sizings, keep a DIY solver in reserve. If it revolves around playing better in standard spots, the library covers you and the drill loop is the part GTO+ hasn't shipped yet.

2. GTO Wizard: the Deepest Library, at Subscription Prices

GTO Wizard is the biggest name in browser GTO study and its presolved library is the deepest on the market, a fact we don't argue with. Upper tiers add custom AI solving and node locking, which makes it the closest thing to "GTO+ plus a library" in one product. The cost is the catch: $49 to $279 a month on monthly billing depending on tier, roughly 20% less on annual. Two months of the mid tier costs more than a GTO+ license, and the tier that includes custom solving costs more per month than GTO+ costs forever. We break the tiers down in our GTO Wizard pricing analysis and the wider field in GTO Wizard alternatives.

3. Deepsolver: Custom Solving in a Browser

Deepsolver is the straightest answer to "I want the GTO+ workflow but I don't have a Windows PC." It's a cloud solver: you configure a spot in the browser, their servers run it, and both plans include unlimited calculations plus a GTO trainer. It costs $49/month for Essential or $69/month for Pro, dropping to $29.40 and $41.40 per month on yearly billing, and you get two days to test it before committing. Two honest caveats from their own pages: it needs a solid internet connection, and it doesn't support mobile devices. You're renting a faster GTO+ in a browser tab, not putting a solver in your pocket.

4. PioSolver: the Upgrade Path, Not the Escape Path

If your problem with GTO+ is capability rather than platform, PioSolver 3 is where you'd go: scripting, aggregation reports, and a decade of community workflows built around it. Pro costs €450 and Edge €800, both plus tax and both with one year of updates included. But note what it doesn't fix. Pio is Windows-only too, still DIY, and six times the price. For most people reading this page it's the wrong direction, which is exactly what our PioSolver alternatives guide is about.

5. TexasSolver: the Free One

TexasSolver is an open-source postflop solver under the AGPL v3 license with a GUI, about 2.5k GitHub stars, and builds for Windows, macOS and Linux. Its own benchmarks show results aligned with PioSolver on matched spots. For a Mac user who wants the GTO+ experience at GTO+ accuracy, this is the honest zero-dollar answer, and we said as much in our poker solver roundup. The trade is polish: rougher interface, no vendor support, and the same DIY tree-building burden as every other solver on this list. Free software is only free if your time is.

What Two Years of Study Actually Costs

One-time purchases and subscriptions are hard to compare in a single glance, so here's the arithmetic over two years of continuous use, list prices as of September 1, 2026, annual billing where it's offered.

GTO+ wins this chart and we're not going to pretend otherwise. The question the chart can't answer is what those dollars buy per hour of your study time. Two years of GTO+ is two years of building trees before you can ask a question. Two years of a library is two years of asking questions.

Who Should Choose What

You have a Windows PC, $75, and enjoy the research itself. Buy GTO+. Genuinely. It's the best value in DIY solving and the bundled CardRunners EV license is a nice extra.

You're on a Mac. TexasSolver if you want to run your own solves for free, GTO Gecko from the Mac App Store if you want the answers already solved and a trainer on top.

You study on your phone, in queues, between sessions. A presolved mobile library is the only format that survives real life. That's GTO Gecko on iOS and Android, and it's the conclusion 43 GTO+ searchers reached on their own in three and a half months.

You want custom solving without owning hardware. Deepsolver in the browser, or GTO Wizard's upper tiers if you also want the library and can carry the monthly price.

You run scripted aggregation research for a living. PioSolver Edge. Nothing else on this page replaces it.

Switching from GTO+: What You Keep and What You Lose

Nothing transfers. No platform here imports GTO+ savefiles, so your solved trees stay on the Windows machine that made them. What you lose going to any presolved library is control: custom ranges, custom sizings, node locking, and the ability to solve a straddled live-game monstrosity nobody precomputes. (GTO Gecko's cash trees do include a 200bb straddle profile, which covers the most common of those requests.)

What you gain is time and repetition. Setup is a login rather than an install, the first solved spot is seconds away, and the drill loop that turns knowledge into instinct exists today instead of in a future release. The pattern we see across 22,500+ players in 175 territories is consistent: people don't stop studying because the answers were wrong. They stop because the workflow was work.

FAQ

Is GTO+ still being updated in 2026?

Yes. The official download page lists a v1.9.1 beta dated June 23, 2026, following a v1.8.9 stable release in February 2026, and the beta notes describe engine work for an upcoming trainer. Anyone telling you GTO+ is abandoned is out of date.

Does GTO+ run on Mac?

No. The requirements are Windows 7 or higher; there's no macOS build. Mac users can run it in a Windows virtual machine, or go native with TexasSolver (free, DIY) or GTO Gecko (presolved library and trainer, Mac App Store).

Is there a GTO+ mobile app?

No. Searching "GTO+" on the App Store returns unrelated apps with a plus sign in the name, because the real GTO+ exists only on Windows desktop. Our ad data puts numbers on that dead end: 43 attributed GTO Gecko installs in 108 days came from GTO+ search terms alone.

Is GTO+ as accurate as PioSolver?

For standard heads-up postflop solving, effectively yes. Both converge on Nash equilibrium, and independent comparisons on matched settings find near-identical strategies and EVs. Pio earns its higher price with speed on large trees, scripting and aggregation tooling, not with better answers.

What does GTO+ actually cost?

$75 one-time for the first license and $40 for a second, with all future updates included and a CardRunners EV license bundled, per the official purchase page as of September 1, 2026. One license covers one computer.

What's the cheapest GTO+ alternative?

TexasSolver, which is free and open source, if you want to keep running your own solves. If what you want is presolved answers plus a trainer, GTO Gecko's single-format plan at $149.99/year is the cheapest full library on this page, and the web app's free tier with daily limits costs nothing to try.
