Flopzilla and Equilab taught a generation of poker players how to think in ranges. Ask any winning reg over 30 what software they studied with before solvers existed, and you will hear one of these two names. Both tools earned their reputation honestly: they were cheap or free, blazingly fast, and they made abstract range concepts visible on screen.
There is just one problem. Both are Windows desktop programs from another era, and neither has ever shipped a Mac, mobile, or web version. If you grind on a MacBook, study on your phone, or simply want tools that reflect how poker is actually studied in 2026, you need alternatives. This guide covers what made Flopzilla and Equilab great, where they fall short today, and which modern tools do the same jobs better, starting with options that cost nothing.
What Made Flopzilla and Equilab So Popular?
Flopzilla and Equilab dominated poker study from roughly 2010 to 2018 because they were fast, affordable, and visual. Flopzilla (a $25 one-time purchase) showed exactly how a range connects with any flop. Equilab (completely free) calculated hand-vs-range and range-vs-range equity in seconds. Nothing else at the time came close for the price.
Flopzilla's core trick was board texture analysis. You enter a preflop range, deal a flop, and instantly see what percentage of that range flopped top pair, a flush draw, a gutshot, or air. Then you filter: keep only the hands that continue against a bet and see how the range changes on later streets. For learning how ranges interact with boards, it was genuinely ahead of its time.
Equilab, built by PokerStrategy.com, attacked a different problem: equity. It answered questions like "how much equity does A♠K♠ have against a 15% opening range?" It shipped with preset ranges, a scenario analyzer, and even a built-in equity trainer. The price tag of zero made it the default first tool for millions of players.
Respect where it is due: both programs still do their original jobs fine. The problem is not that they got worse. It is that the rest of poker software moved on without them.
Can You Run Flopzilla or Equilab on a Mac?
No. As of June 2026, neither Flopzilla nor Equilab has a native Mac version, and neither has a mobile app or web version. Mac users must run Windows through Parallels, Boot Camp, or a virtual machine just to open them. The practical alternative for Mac, iPhone, and Android users is a browser-based or native cross-platform tool.
The workarounds all carry friction. Parallels costs more per year than Flopzilla costs once. VirtualBox is free but clunky, and Wine-based hacks for Equilab break with macOS updates. You end up maintaining an entire Windows installation to run a single equity calculator, which made sense in 2014 and makes very little sense now.
For quick equity work on a Mac (or any device with a browser), a free tool like the GTO Gecko poker odds calculator covers the core Equilab use case with zero installs: hand vs hand, hand vs range, on any street. If you want a full study platform rather than a single calculator, GTO Gecko also ships a native macOS app alongside its web, iOS, and Android apps, with one subscription synced across all of them.
Flopzilla vs Equilab: What Is the Difference?
Equilab is a free equity calculator: it tells you how often a hand or range wins. Flopzilla is a paid range-analysis tool: it tells you what a range is made of on a given board. They overlap on basic equity math, but serious students historically ran both, because each does one job the other does poorly.
| Feature | Flopzilla / FlopzillaPro | Equilab |
|---|---|---|
| Price | $25 one-time (lifetime) | Free |
| Platforms | Windows only | Windows only |
| Core strength | Range vs board breakdown, filtering | Fast range vs range equity |
| GTO strategy output | None | None |
If you forced a choice between the two on a Windows machine, Flopzilla is the deeper study tool and Equilab is the faster answer machine. The last row of that table is the one that matters in 2026, though. Neither tool tells you what to do with the information it gives you. More on that below.
Where Flopzilla and Equilab Are Stuck
Both tools share four structural limitations in 2026: they run only on Windows, they output equity rather than strategy, they have no solver integration, and their interfaces predate modern UX standards. None of these is fixable with an update. They are equity-era tools living in a solver-era game.
Walk through each one. The Windows lock-out grows worse every year as more players study on Macs, tablets, and phones. A study tool you can only open at your desktop PC is a study tool you use less.
The strategy gap is the bigger issue. Knowing your range has 54% equity on K♥8♦3♣ is a starting point, not an answer. Should you bet 33% pot or check your whole range? Which hands check-raise? Equity calculators cannot say, because the answer depends on how both full ranges play across every future street. That is a solver question, and these tools were built a decade before solver output became the standard of proof in poker study.
To be fair, Flopzilla is not abandoned software. The $25 license now covers FlopzillaPro (effectively Flopzilla 2), and it still receives updates, with a new build shipping as recently as December 2025. Equilab, by contrast, has been essentially frozen for years. PokerStrategy points upgraders toward Power-Equilab, a paid third-party successor.
The Best Flopzilla and Equilab Alternatives in 2026
The best alternative depends on the job. For free equity and range work on any device, GTO Gecko's web tools and free range library cover both legacy use cases. For Windows die-hards, FlopzillaPro and Power-Equilab remain solid. For players who want strategy output rather than raw equity, a solver platform is the real upgrade.
| Tool | Price (June 2026) | Platforms | Best for |
|---|---|---|---|
| GTO Gecko | Free tier; paid from $24.99/mo | Web, iOS, Android, macOS | Equity + ranges + GTO on any device |
| FlopzillaPro | $25 one-time | Windows | Deep board-texture filtering |
| Power-Equilab | From ~$3.49/mo | Windows | Advanced Equilab-style equity work |
| PioSolver | $249-$475 one-time | Windows | Running your own custom sims |
GTO Gecko: Free Equity and Range Tools on Any Device
GTO Gecko's free tier replaces both legacy tools without an install. The free poker odds calculator handles the Equilab job: equity for any matchup, in the browser, on whatever device you are holding. The free preflop range library handles the Flopzilla-adjacent job of studying real range construction, with solver-built opening and defending ranges for every position. Both are permanently free, with no credit card required. There is also a free MTT bankroll calculator if tournaments are your thing.
The difference shows up when you want more than equity. The paid platform adds a massive presolved library of preflop and postflop solutions for Cash, MTT, and Spin & Go, true 3-way multiway postflop solutions (still rare in the market), a built-in solver for custom spots, and three trainers with ELO tracking that re-serve the spots you misplay. An explainability engine breaks down why the solver action is right in plain English, which is exactly the layer Flopzilla never had: not just "your range hits this board 38% of the time," but "here is the play, and here is why."
Pricing as of June 2026: a single format runs $24.99/month or $149.99/year (about $12.50/month effective), and all-access covers all three formats at $39.99/month or $239.99/year. It is rated 4.8 stars across 595+ app-store ratings, with 22,500+ players in 175 territories. You can browse the free preflop library and odds calculator on GTO Gecko right now and see whether it covers your old Flopzilla and Equilab workflow before paying anything.
FlopzillaPro: The Honest Pick for Windows Loyalists
If you are on Windows and you specifically love the filter-down-the-streets workflow, FlopzillaPro is still excellent at it. The $25 lifetime license covers two computers and includes both the original Flopzilla and the Pro version, and the developer keeps shipping updates. For pure board-texture exploration at that price, nothing modern undercuts it. Its limits are the same as ever: no Mac, no mobile, no GTO output.
Power-Equilab: Equilab With the Missing Features
Power-Equilab is what Equilab would have become with continued development: weighted ranges, deeper scenario analysis, and more flexible equity calculations, from roughly $3.49/month as of June 2026 (cheaper paid annually). It is the natural upgrade for players who outgrew free Equilab but want to stay in that exact workflow. It remains Windows-only, so the Mac and mobile problem stands.
Full Solvers: When Equity Stops Being the Question
If your study questions have shifted from "what is my equity?" to "what is the play?", an equity calculator upgrade will not get you there. PioSolver ($249 for Pro, $475 for Edge, one-time, Windows-only as of June 2026) is the pro standard for running your own simulations, though it has no trainer, no presolved library, and a steep learning curve. Our PioSolver alternatives guide covers the easier paths, and the broader best poker solvers roundup compares the whole field.
Why Is a Solver Better Than an Equity Calculator?
An equity calculator tells you the score; a solver tells you the play. Equity is a single number describing how often you win at showdown. Strategy is a full plan: which hands bet, which size, which hands check-raise, and how every decision changes on each runout. Equity is an input to that plan, never the plan itself.
Here is a concrete example. Give A♠5♠ to Equilab on Q♥7♥2♦ against a big blind defending range and it reports something like 45% equity. Useful, but ambiguous. A solver looking at the same spot says: bet small at high frequency, because the hand has a backdoor nut flush draw, an overcard, and it blocks the ace-high hands that continue against you. One tool hands you a number. The other hands you a decision with a reason attached.
This is the deeper shift the legacy tools missed. Flopzilla-style range breakdowns and Equilab-style equity numbers are now intermediate steps that solvers compute internally on the way to an answer. Understanding how equity actually works and how it interacts with pot odds is still essential foundation work. So is counting combos within a range. But once the foundations are in place, the highest-value question changes, and our guide on how to use a poker solver picks up exactly where the equity tools leave off.
None of this means you wasted your time with the old tools. Players who studied with Flopzilla tend to read solver outputs faster, because they already think in range-vs-board terms. The skills transfer. The software just does not.
Flopzilla and Equilab FAQ
Is there a Flopzilla version for Mac?
No. As of June 2026, Flopzilla and FlopzillaPro run only on Windows. Mac users need Parallels, Boot Camp, or a virtual machine. If you want native range analysis on a Mac, use a cross-platform tool instead; GTO Gecko, for example, runs in the browser and also ships a native macOS app.
Is Equilab still free?
Yes. The original PokerStrategy.com Equilab remains free to download for Windows, and an Omaha version exists as well. Development has been dormant for years, though, and the feature-extended successor, Power-Equilab, is a paid subscription from about $3.49/month as of June 2026.
What is the best free alternative to Flopzilla?
For range study, the free preflop range library on GTO Gecko lets you browse solver-built ranges for every position on any device. For the equity side of the workflow, GTO Gecko's free poker odds calculator runs in any browser. Neither requires a download, a Windows PC, or a credit card.
Can I use Flopzilla or Equilab on my phone?
No. Neither tool has ever released an iOS or Android app, and there is no web version of either. They are desktop Windows programs. Players who study on mobile need a different stack entirely, which is a major reason modern platforms ship native apps across iOS, Android, and the web.
Is Flopzilla still worth it in 2026?
For a Windows player who wants a cheap, focused board-texture tool, yes; $25 once for a still-maintained program is fair value. For everyone else, no. It cannot follow you off the desktop, and it stops at equity and range composition exactly where modern study, driven by solver output, begins.
Keep the Skills, Retire the Software
Flopzilla and Equilab deserve their place in poker history. They made range thinking accessible for the price of a buy-in or less, and the mental models they taught still hold up. The programs themselves do not. Windows-only software with no strategy output is a poor fit for how poker is studied in 2026, no matter how fondly we remember it.
The upgrade path costs nothing to test. Run a few matchups through the free odds calculator, browse the free range library, and use the daily free trainer hands on play.gtogecko.com to see what equity work looks like when a solver sits behind it. If it covers your old workflow, you just got Flopzilla and Equilab back, on every device you own, with the strategy layer they never had.
