Gamma exposure (GEX) tools have gone from a niche quant concept to a mainstream part of 0DTE and SPX trading, and at least ten credible platforms now serve the space at very different price points. Most of them share one design decision: they hand you data and leave the interpretation to you. One of them — StrikeGEX, which we build, so weigh our placement accordingly — took the opposite bet: an AI engine computes the levels, a heatmap makes them readable at a glance, and the daily call gets graded in public. Here's the honest field guide.
| Tool | Entry price | Top retail tier | Best known for |
|---|---|---|---|
| StrikeGEX | $69 (14-day trial) | $249/mo ($1,990/yr) | AI-computed 0DTE levels, one-glance heatmap, public daily grading, 304 symbols |
| Skylit (Heatseeker) | $99.99/mo (Community) | $699/mo (Pro, 300+ tickers) | Multi-mode analytics (Trinity, Swing, vanna), established community |
| SpotGamma | $89/mo (Standard) | $299/mo (Alpha) / $1,999+ Institutional | Real-time HIRO flow indicator, years of published research |
| MenthorQ | Free tier | $129/mo (Premium) / $349/mo (Pro) | Cross-asset gamma (stocks, ETFs, futures, crypto), AI assistant "Quin" |
| GEXBot | $50/mo (Classic) | $350/mo (Quant); State $150, Orderflow $250 | Transparent tiered pricing, per-second GEX, 56+ tickers |
| Unusual Whales | Free tier / $50/mo (Retail Basic) | Up to $200/mo (Professional) | Options flow, dark pool, congressional data breadth — not GEX-first |
| GEXStream | Free 3-day trial / $39.50/mo (Basic) | $199.50/mo (Quant) | Budget real-time GEX/IV analytics, heatmaps, options inventory |
| Gamma Sonar | Free 7-day trial | $249/mo (one plan) | 16+ tool suite, five proprietary signals, 103 tickers |
| Volland | $99/mo (VolHacks) | $1,000/mo (Universe) / $5,000+ Institutional | First- to third-order dealer Greeks, ~1,000 tickers, deep raw data |
| FlashAlpha | Free tier (no signup) | $1,499/mo (Alpha); Growth $299 | Options-analytics API, 6,000+ tickers, free no-signup GEX charts |
StrikeGEX is the only tool on this list where the interpretation is the product. Its proprietary server-side engine names the levels (King Node, walls, air pockets), renders them on a heatmap designed to be read in one glance, and issues a live Commander verdict on who controls the tape. It's also the only platform here that grades its own daily call against the actual close, in public, every trading day. Scope is deliberate: SPX/SPY/QQQ/IWM 0DTE first, 304 symbols via StrikeMap, one $249 plan with everything included. If the 0DTE index session is your trading day, this is the tool shaped exactly like it.
Skylit (Heatseeker) has a wide feature bench for traders who want more than gamma alone — vanna exposure, Trinity Mode, Swing Mode — across 300+ tickers, with an established community. The cost is real: $699/month at the Pro tier is the highest retail (non-institutional) price on this list, and the entry Community tier is $99.99/month. The levels are yours to interpret; there's no graded call.
SpotGamma is among the most established brands here, with a long public research history. HIRO, its real-time flow indicator, is distinctive — but it unlocks at the $299/mo Alpha tier, above StrikeGEX's all-inclusive price. Below that you're buying levels plus written commentary to synthesize yourself. Institutional tier from $1,999/mo.
MenthorQ goes broadest on asset classes — stocks, ETFs, indices, futures, and crypto gamma levels — plus an AI assistant, Quin, that answers questions about the data (an assistant you query, as opposed to an engine that computes the answer). A genuine free tier makes it costless to look at, with Premium at $129/month list and Pro at $349/month. Less 0DTE-index-specific than the dedicated tools here.
GEXBot is the raw-data pick: transparent a-la-carte tiers from $50/month, per-second GEX, 56+ tickers, and an API at the top. You derive the levels from the profiles yourself — a full workflow stacks tiers to $250–$350/month, at which point you've paid StrikeGEX money for data without interpretation or grading.
Unusual Whales isn't primarily a GEX tool — it's an options-flow, dark-pool, and alt-data platform that includes gamma charts as one feature among many, from free up to $200/month. Excellent at its actual job; traders who need a dedicated gamma-level workflow typically pair it with a GEX-first tool rather than use it standalone.
Our AI engine publishes its King Node call every trading day and grades it against the close in public. Check the record at /recaps, then take the $69, 14-day full-access trial.
