Free Poker Solver 2026: 6 Real Options (Browser & Desktop)

The Short Answer

Yes, there are free poker solvers in 2026 — but only two of them let you solve your own spots, and both are unmaintained open-source projects. Here is everything free that is worth your time, in order of how much real solving you get:

1. WASM Postflop — a free, open-source GTO solver that runs in your browser. You enter ranges, board and bet sizes and it solves the spot on your own CPU. Postflop only, heads-up, development stopped in October 2023.
2. Desktop Postflop — the same engine as a desktop app for Windows and Linux, roughly twice as fast as the browser version. Also free, also no longer developed.
3. GTO Wizard Free — a free account on GTO Wizard's pre-solved library. No custom solving, but a polished way to see what solver strategies look like.
4. PioSolver's free version — still offered for evaluation, but it only solves one fixed sample flop (Qs Jh 2h). It tells you whether your PC runs Pio well; it is not a study tool.
5. DEEPFOLD's free preflop drills — not a solver: you play hands against precomputed solver answers (open-raising, facing raises, push/fold, multiway). 5 hands without an account, 10 a month on a free one.
6. DEEPFOLD Free — not a solver either: AI review of hands you actually played, 3 uploads and 10 questions a month.

If you searched for a browser poker solver: WASM Postflop is the one that really solves custom spots in a browser tab, for free. Everything else free in the browser shows pre-solved output.

What no free tool does in 2026: preflop solving, multiway postflop trees, or active development and support. For those you are paying — PioSolver (€450 Pro / €800 Edge, one-time), a GTO Wizard subscription, or a bundle like DEEPFOLD PRO.

How We Checked These

For each option we confirmed in October 2026 that it is still available, what platforms it runs on, and what you can and can't do without paying. Open-source details (license, last update, platforms) come from the projects' own GitHub pages; PioSolver's free version is described on piosolver.com. We don't list anything we couldn't confirm still works, and we don't link to cracked software.

Option 1: WASM Postflop — a Real Solver in Your Browser

WASM Postflop is a free, open-source (AGPL-3.0) solver written by an independent developer. It compiles a Discounted CFR solver to WebAssembly, so it runs inside the browser on your own machine — nothing is uploaded and nothing is installed.

What you get:

• Custom postflop solves: your own ranges for both players, any flop, turn or river, your own bet and raise sizes
• Multithreading, so it uses all your CPU cores
• A memory-saving 16-bit mode that, by the author's benchmarks, uses about as much memory as Pio does
• Works on any OS with a modern desktop browser — including Mac, where most desktop solvers don't run

Limits:

• Postflop and heads-up only. No preflop solving, no three-way pots.
• Development was suspended in October 2023 (the author moved on to a commercial solver). It still works, but there are no fixes or new features, and nobody to ask for help.
• About 2x slower than the desktop version of the same engine, by the author's own numbers.
• Wide-range trees with several bet sizes need a lot of RAM; a browser tab is not the place for huge trees.

Best for: Anyone who wants to run real solves for free, especially on a Mac, and is comfortable building trees themselves.

Option 2: Desktop Postflop — the Same Engine, Faster

Desktop Postflop is the native app version of WASM Postflop, by the same author and under the same AGPL-3.0 license. Releases are published for Windows (installer or portable .exe) and Linux (AppImage / .deb). There is no Mac build.

What you get:

• Everything WASM Postflop does, roughly twice as fast
• No browser memory limits — the tree can use your machine's full RAM

Limits:

• Same scope: heads-up postflop only
• Last release in 2023, development suspended
• No Mac version

Best for: Windows or Linux players who liked WASM Postflop and want faster solves.

Option 3: GTO Wizard Free

GTO Wizard is a cloud library of pre-solved spots. Its free account lets you sample that library:

What you get:

• A limited set of solved spots to browse
• A look at strategy mixes and the interface
• A preview of its trainer

Limits:

• Most spots and the full trainer sit behind paid plans — see our GTO Wizard pricing breakdown for what each tier unlocks
• No custom solving on the free plan: you see what has been solved, not your own spot

Best for: Seeing what solver output looks like, or testing GTO Wizard before paying. For the head-to-head with a desktop solver, see GTO Wizard vs DEEPFOLD-SOLVER.

Option 4: PioSolver's Free Version

PioSolver, the industry-standard desktop solver, offers a free version for evaluation. It only solves a fixed sample flop (Qs Jh 2h).

What it's for: checking that your hardware runs Pio well before you buy, and getting a feel for PioViewer. It can't solve your own spots.

What Pio costs: two editions, Pro €450 and Edge €800 (adds the preflop solver), one-time with a year of updates. Windows only; Mac users run it through Parallels or Boot Camp. More in our PioSolver review.

About "free PioSolver" downloads: cracked copies are pirated software and a common way to get malware. If the price is the problem, WASM Postflop and Desktop Postflop are free and legal.

Option 5: DEEPFOLD's Free Preflop Drills (Not a Solver)

The free solvers above are postflop-only. For preflop, the free option is to practise against precomputed solver answers:

• Open-raise (RFI) drill — raise or fold by position
• Facing-a-raise drill — fold, call or raise against opens, 3-bets, 4-bets and 5-bets
• MTT push/fold drill and a free push/fold chart by stack depth and position
• Multiway preflop spots — squeezes, cold-calls, cold 4-bets

Limits: these are precomputed answers, so you can't change ranges or sizes; 5 hands without an account, then 10 hands a month on a free account.

Best for: drilling preflop decisions until they're automatic — the part of the game free postflop solvers don't cover.

Option 6: DEEPFOLD Free (AI Hand Review, Not a Solver)

A solver answers "what's the equilibrium in this spot?". Most players' real question is "what did I do wrong in the hand I lost last night?". DEEPFOLD Free is an AI coach for that: upload a hand history or paste an X-Poker / PokerCraft link and it reviews the decisions.

Free plan: 3 hand-history uploads and 10 AI questions a month. Screenshot analysis and DEEPFOLD-SOLVER are paid features.

Comparison Table

Free Tools That Help Next to a Solver

• Equity calculator: before solving anything, check raw equity. Our free poker odds calculator gives exact equity for 2–6 hands on any board, in the browser.
• Push/fold chart: for short-stack MTT spots, a push/fold chart answers most decisions without a solver.

When Free Ends and Paid Begins

Free is enough if:

• You want to learn how solvers think by running a few heads-up postflop spots (WASM Postflop)
• You study 1–2 times a week and mostly need preflop habits and the occasional hand review
• You are testing whether structured study fits your routine at all

You'll outgrow free when:

• You want preflop solving, or multiway pots
• You want software that is still maintained, with support when something breaks
• You want solves fast enough to check spots in the middle of a review session
• You want your own hands reviewed regularly, not just theory

At that point the realistic choices are PioSolver (€450 / €800 one-time, Windows), GTO Wizard (subscription, pre-solved library), or DEEPFOLD PRO at $25/month ($19/month billed yearly), which bundles the GPU desktop solver for Windows with AI hand review and unlimited drills. The PioSolver vs DEEPFOLD-SOLVER comparison has the full trade-offs.

FAQ

Is there a completely free poker solver?

Yes: WASM Postflop (in the browser) and Desktop Postflop (Windows/Linux) are free and open source and solve custom postflop spots. Both are heads-up postflop only and haven't been updated since 2023.

Is there a poker solver that runs in the browser for free?

WASM Postflop. It runs the solve on your own computer inside the browser tab, so it is free to use and works on Mac too. It is slower than desktop solvers and limited to heads-up postflop spots.

Is there a free GTO solver for preflop?

Not one we could confirm in 2026. Free solvers are postflop-only. For preflop, the free options are precomputed: GTO Wizard's free library and DEEPFOLD's preflop drills.

Is there a free version of PioSolver?

Yes, for evaluation only: it solves a fixed sample flop so you can test your hardware. The paid editions are Pro (€450) and Edge (€800). Avoid "free full PioSolver" downloads — they are pirated and often carry malware.

What is the best free poker solver for Mac?

WASM Postflop, because it runs in the browser. Desktop Postflop, PioSolver and DEEPFOLD-SOLVER are built for Windows (Desktop Postflop also has Linux builds); on a Mac, the paid alternative is a cloud library such as GTO Wizard.

Can I get GTO Wizard Premium for free?

There is no legitimate way. GTO Wizard has a free plan with limited access, and paid plans above it.

What's the cheapest full-featured poker solver?

It depends on how you count. PioSolver Pro is €450 once (plus paid support extensions for updates after the first year). DEEPFOLD PRO is $19/month billed yearly and includes a GPU desktop solver plus AI hand review and drills.

Are open-source poker solvers safe to use?

WASM Postflop runs inside the browser sandbox and its source code is public. For any downloaded solver, use the official release page (for Desktop Postflop, its GitHub releases) rather than re-uploads.
