Search for free GTO resources and you mostly find bait. "Free" turns out to mean a seven-day window, a credit card form, or three locked screens between you and anything useful. This roundup is different: everything below is permanently free, verified in June 2026, and worth actual study time.
That includes the free tier on our own platform, which we will describe factually alongside everyone else's. It also includes open-source solvers we do not make a cent from, competitor free plans that are genuinely decent, and an honest section on where free study runs out of road.
What Free GTO Study Tools Actually Exist in 2026?
Genuinely free GTO resources fall into five buckets: free preflop range libraries, open-source solvers like TexasSolver, daily allowances on commercial trainers, free poker math calculators, and YouTube strategy content. None of them expire or require a card. The limitation is depth and volume, not a countdown timer.
| Resource type | Best free options | The catch |
|---|---|---|
| Preflop range libraries | GTO Gecko, Lucid, DTO, Octopi | Postflop stays paywalled |
| Solvers | TexasSolver (open source) | You run every sim yourself |
| Trainers | Daily free hands on several apps | Volume caps |
| Math tools | Odds calculators, Equilab | None, really |
| Video | YouTube strategy channels | Unstructured, easy to watch passively |
If you are brand new to solver-based study, start with our primer on what GTO poker actually means before diving into the tools below. The tools make far more sense once you understand what an equilibrium strategy is trying to accomplish.
Where Can You Get Free GTO Preflop Charts?
Several platforms now give away full preflop range libraries at no cost. GTO Gecko's free tier includes the complete preflop library — every position, stack depth, and pot type across Cash, MTT, and Spin & Go — with no credit card and no expiry. Lucid, DTO, and Octopi also publish free preflop ranges.
Preflop is the logical place for free access because it is finite. There are 169 starting hands and a manageable number of common spots, so giving the charts away costs platforms little while postflop libraries stay behind the paywall. Take advantage of that: preflop is also where most low-stakes money is lost, as we covered in our guide to GTO opening ranges by position.
Here is the free preflop landscape as of June 2026:
- GTO Gecko: the full preflop range library free, browsable on web, iOS, Android, and macOS. Includes raise-first-in, facing-a-raise, 3-bet, and 4-bet nodes with mixed frequencies shown, not simplified pure-strategy approximations. You can browse the free preflop library on GTO Gecko without creating anything more than a login.
- Lucid: free preflop ranges for Cash, Live, MTT, and Spins, plus a daily GTO quiz called Cardle. A solid free tier from the Doug Polk-backed platform.
- DTO: free preflop ranges on the cash side, with the trainer-first design the platform is known for.
- Octopi Poker: the free Community plan includes preflop range exploration plus access to weekly coaching sessions and their Discord, which is unusually generous for video content.
One warning about random chart PDFs floating around forums: many are years old, simplified to pure strategies, or built for sizings nobody uses. A 2018 chart assuming a 3x open at 100bb will steer you wrong in today's 2.2x-2.5x games. Prefer a maintained library over a static download, and learn how ranges actually work rather than memorizing colors on a grid.
Is There a Completely Free Poker Solver?
Yes. TexasSolver is a fully open-source GTO solver, free for personal use, with a GUI for Windows, macOS, and Linux. It solves the same equilibrium math as commercial desktop solvers and benchmarks competitively with them in common configurations. The cost is your own time: you configure and run every simulation yourself.
For a tool that costs nothing, TexasSolver is remarkable. You set the ranges, bet sizes, and board, hit solve, and get real equilibrium strategies you can drill into street by street. The project lives on GitHub, and a newer GPU version speeds up solves dramatically if you have the hardware. There is also wasm-postflop, an open-source solver that runs in your browser. Its development is suspended, but it still works and remains a quick way to check a single spot.
Now the honest part. Free solvers come with three real costs:
- Setup skill. A solver output is only as good as its inputs. Feed it the wrong preflop ranges or miss a bet size the spot needs, and you get a confident-looking answer to a question nobody asked. Our guide on how to use a poker solver covers the input mistakes that ruin sims.
- Compute time. Complex trees take minutes to hours on a laptop. Studying twenty flops means twenty solves.
- No library. Commercial platforms sell presolved databases precisely because solving everything yourself does not scale. With a free solver you study one spot at a time, deeply. That is valuable, but it is a different activity from reviewing a session.
If you outgrow free and want to stay cheap, GTO+ is the long-standing budget option at $75 one-time (verified June 2026): a capable desktop solver from the Flopzilla developers, Windows-only, no presolved library.

Which Free GTO Trainers Are Worth Using Daily?
You can build a real daily drilling habit from free allowances alone. GTO Gecko gives you free trainer hands every day on its preflop, postflop, and full-hand trainers. GTO Wizard's free plan allows 10 practice hands per day, DTO offers free spots, and Octopi's Community plan includes button-position drills.
Drilling matters more than reading. Knowing the button opens 43% of hands is trivia; folding K♠5♠ from UTG without thinking is skill. Trainers convert the first into the second through repetition with instant feedback.
| Trainer | Free allowance (June 2026) | Notes |
|---|---|---|
| GTO Gecko | Daily free hands, all 3 trainers | Preflop, postflop, and full-hand modes; graded against the solver |
| GTO Wizard | 10 practice hands/day, 1 postflop spot/day | Plus 5 analyzed hands per month |
| DTO | Free spots + free cash preflop ranges | Trainer-first design, strongest for MTT |
| Octopi | Button-spot drills + weekly coaching | Community plan, MTT-centric |
| Lucid | Daily Cardle quiz + preflop ranges | One puzzle a day with solver reasoning |
A practical trick: stack the allowances. Run your GTO Gecko hands, then GTO Wizard's ten, then the daily Cardle. That is a 15-20 minute routine costing nothing, and it beats an hour of passive video. GTO Gecko's trainers are also on iOS and Android, so the daily hands fit into a commute.
Each platform's free trainer has a different personality, which is genuinely useful: GTO Wizard's practice mode is polished, DTO's tournament spots are well chosen, and Octopi's weekly coaching gives you human explanation that pure drilling lacks. For how these platforms compare beyond their free tiers, see our guide to the best GTO apps and platforms.
What Free Poker Calculators Should You Bookmark?
Two categories cover most needs: equity calculators and bankroll tools. GTO Gecko's free poker odds calculator handles hand-vs-hand and hand-vs-range equity in the browser with no signup, and the free MTT bankroll calculator tells you what buy-ins your roll supports. Equilab remains the free desktop standard.
Equity intuition is the cheapest edge in poker. Most players guess at numbers a calculator would correct in five seconds: A♠K♠ against a pair of queens is a near coin flip at roughly 46%, while A♥K♦ offsuit drops about three points. Run enough matchups and the estimates start coming pre-installed at the table. Pair the calculator with our guides on poker equity and pot odds math and the numbers stop being abstract.
Equilab, from PokerStrategy.com, deserves its longevity. It is a free Windows program with range-vs-range equity, a scenario analyzer, and an equity trainer, plus a separate Omaha version. Its limits: Windows only, no mobile or Mac version, and a 2010s interface. The bankroll side is less glamorous but more important. Going broke ends more poker careers than bad strategy does, a point we hammer in bankroll management for serious players.
Which YouTube Channels Teach Real GTO?
Three channels consistently deliver solver-grade content for free: GTO Wizard's channel for theory deep-dives, Jonathan Little for daily hand analysis at high volume, and Upswing Poker for accessible strategy breakdowns. Add final-table replay channels, where you watch full tournaments with every hole card exposed.
The GTO Wizard channel is the strongest pure-theory resource on the platform. Their aggregate-report videos and range-construction breakdowns would have been paid course material a decade ago. Credit where due: it is excellent marketing because it is excellent content.
Jonathan Little posts several videos a week across thousands of uploads, mostly hand reviews, which train a different muscle than theory lectures. Upswing's channel covers common mistakes and bet-sizing concepts in plain language. And the replay tip is underrated: search for final table replays with hole cards up, pause before each decision, and decide before the player does. It is free range-reading practice against real fields.
One caution: YouTube optimizes for watch time, not your win rate. An hour of video feels like study and often teaches less than ten drilled hands with feedback. Watch with a notebook, or watch less.
What Free Gets You — and Where It Stops
Free resources fully cover preflop ranges, poker math, daily low-volume drilling, and conceptual theory. They stop at postflop depth, study volume, leak tracking, multiway solutions, and ICM. That boundary is not an accident: platforms give away what is finite and charge for what is deep.
Be realistic about what that boundary means for your game. A disciplined player using only free tools can absolutely beat low stakes, because low-stakes losses are dominated by preflop spew and basic math errors, which are exactly what free resources fix. Plenty of paying subscribers lose to free-tier grinders who actually do the reps.
The ceiling appears postflop. Free tiers give you one spot a day or one slow self-solved sim at a time, and postflop competence is a volume problem: thousands of flop, turn, and river decisions across textures and pot types. Statistics are the other gap. Free tools grade individual hands but rarely track patterns across hundreds of them, and your biggest leaks are patterns, not single mistakes. ICM is thinnest of all: almost no quality ICM-adjusted content is free anywhere, because the sims are expensive to produce.
When you do hit that ceiling, the paid market spans a wide range. As of June 2026, GTO Wizard runs $49 to $279 per month after its March repricing (we break the tiers down in our GTO Wizard pricing guide), GTO+ is $75 once, and GTO Gecko starts at $24.99/month or $149.99/year for a single format — with the free tier above remaining free regardless. Whatever you pick, pick it because free study created a specific need, not because an ad created a vague one.
A Free-Only Weekly Study Plan
Here is a complete weekly routine using nothing above. It takes about 30 minutes a day:
- Daily: burn every free trainer allowance you have: GTO Gecko hands, GTO Wizard's ten, the Cardle. Treat misses as homework, not noise.
- Twice a week: pick one position in the free preflop library and study it until you can reproduce the range from memory. UTG one session, button the next.
- Weekly: take the single hand that confused you most at the tables and solve it in TexasSolver. One deep sim beats five shallow ones.
- Weekly: one YouTube video, chosen in advance, watched with notes. Then close the tab.
- Monthly: rerun your numbers in the bankroll calculator and adjust stakes honestly.
Run that loop for three months and you will pass most of your player pool, free.
Free GTO Resources FAQ
Is there a completely free GTO solver?
Yes. TexasSolver is open source and free for personal use on Windows, macOS, and Linux, with both a GUI and a console version. It produces real equilibrium solutions comparable to paid desktop solvers. The tradeoff is that you configure and run every simulation yourself, with no presolved library to browse.
Is GTO Wizard free to use?
Partially. As of June 2026, GTO Wizard's free plan includes one postflop spot per day, up to 10 practice-mode hands per day, and 5 analyzed hands per month. Full library and analysis access requires a paid plan, which now runs $49 to $279 per month after the March 2026 price change.
Are free preflop charts good enough to beat low stakes?
For the preflop portion of your game, yes. Free libraries from GTO Gecko, Lucid, and others contain the same solver-derived ranges paid users see. Low stakes are beatable on tight-solid preflop play plus basic postflop discipline. The gap free charts cannot close is postflop execution, which needs drilling volume.
What is the best free GTO trainer?
Combine them rather than choosing. GTO Gecko offers daily free hands across preflop, postflop, and full-hand trainers; GTO Wizard's free plan adds 10 practice hands a day; Lucid's Cardle adds a daily reasoning puzzle. Stacked together, that is a meaningful daily routine at zero cost.
How much does poker software cost if I outgrow free tools?
As of June 2026: GTO+ is $75 one-time for a self-solve desktop tool. Subscription platforms with presolved libraries range from $24.99/month (GTO Gecko, single format) to $279/month (GTO Wizard's top tier). Most players should exhaust free preflop and drilling resources before paying for anything.
Start With the Free Shelf
The free GTO ecosystem in 2026 is better than the paid ecosystem of 2018. An open-source solver, complete preflop libraries, daily graded drills, and free calculators cover everything a developing player needs for months. The players who plateau on free tools are almost never limited by the tools.
If you want one place to start today, open the free preflop library and trainer on GTO Gecko — no card, no countdown — and burn your first set of daily hands. The rest of this list will still be free tomorrow.
