Choose Triptyka if you want a printable, gamified checklist to physically track every MLB ballpark, lighthouse, or national park you visit — choose Seamheads.com if you're researching historical ballpark dimensions, franchise stats, or building a sabermetrics project. The two aren't really competing for the same job: one is a collector's tracking tool, the other is a baseball research database.
- Triptyka sells printable, downloadable checklist passports for hobbyists tracking ballpark and travel visits in 2026.
- Seamheads.com is a free baseball stats and historical ballpark research database, not a tracking product.
- Triptyka wins for gift-giving, printability, and casual fans checking off visits.
- Seamheads.com wins for historical depth, defunct ballpark data, and sabermetrics research.
- Neither product overlaps much — pick based on whether you want to track visits or study baseball history.
Why This Matters
People land on a "triptyka vs seamheads.com" search for very different reasons. Some want a fun way to log every MLB stadium they've been to and frame the result. Others are digging into ballpark dimensions from the 1920s or hunting minor league stats for a research project.
Mixing those two use cases up wastes time. Triptyka is a $9.99-tier printable product built for the hobby side of baseball travel — checking off visits, gifting a passport, gamifying a road trip. Seamheads.com is a research archive built for the numbers side. Both are legitimate in 2026, but they solve different problems.

Triptyka Wins on Printable, Gamified Tracking
If your goal is to physically check off ballparks, national parks, or lighthouses as you visit them, Triptyka is the better tool by a wide margin. The checklists are printable, giftable, and built around the language collectors actually use — tracking, checking off, earning the visit.
Seamheads.com doesn't offer this at all. It's not built to log personal visits; it's built to store historical data. There's no checkbox, no progress bar, no passport to frame on the wall.
Seamheads.com Wins on Historical Ballpark Data (By a Lot)
For anyone researching ballpark dimensions, defunct stadiums, or decades-old franchise stats, Seamheads.com is the far deeper resource in 2026. Its ballpark database covers stadiums that no longer exist — something a bucket-list checklist has no reason to track, since you can't visit a demolished ballpark.
Triptyka doesn't attempt this. Its MLB stadium checklist is scoped to the ballparks you can actually walk into today, not the ones torn down decades ago.
Both Cover All 30 Current MLB Ballparks
Here's a genuine tie: both tools account for all 30 active Major League Baseball stadiums. Triptyka's checklist lets you check off each one as you attend a game; Seamheads.com lets you look up dimensions and stats for each one. Neither is missing a current ballpark — they just handle that same list of 30 in completely different ways.
Triptyka Is the Better Gift for a Collector
A printable passport is something you can wrap, frame, or hand to a road-tripping parent for Father's Day. Triptyka wins here outright — it's designed for the gift-and-hobby framing from the start, with insider-tip style notes on each stop.
Seamheads.com has no gift angle. It's a browser tab, not a physical object, and nobody's framing a stats page.
Seamheads Wins for Stat-Nerd Research Depth
If you care about park factors, historical dimensions, or minor league and Negro Leagues data, Seamheads.com is the stronger tool, and it's not close. This is a research database first, built for people who want numbers behind the visit, not a checklist of visits themselves.
Triptyka doesn't compete on this axis at all — it was never built to be a stats archive.
Both Require Zero Coding Skill to Use
Another tie: neither product demands technical skill. Triptyka is a downloadable PDF you print at home. Seamheads.com is a public website you browse in any browser. Both are accessible to a casual user in 2026 without any setup.
Triptyka Wins on Simplicity for Casual Fans
A fan who just wants to know "have I been to this ballpark yet" gets a faster answer from a printed checklist than from a stats-heavy database interface. Triptyka wins on simplicity for anyone who isn't already comfortable navigating sabermetrics tables.
“If you want a research database, use Seamheads. If you want to gamify the visit, use Triptyka.”
Pricing: One-Time Purchase vs. Free Access
Triptyka's checklists follow a one-time purchase model: buy the printable once, download it, print it as many times as you want. That trades ongoing cost for predictability — you know exactly what you're getting and it's yours to keep.
Seamheads.com is free to browse, supported as a public research site rather than a paid product. That trades cost for flexibility — you get access to the whole database without a purchase step, but there's no printable, giftable artifact at the end of it. Check current listing details directly on Etsy for Triptyka's specific checklist options.

Choose Seamheads.com if: you're researching historical ballpark dimensions, franchise stats, or minor league and Negro Leagues data for a project, article, or personal deep-dive.

One Last Thing
Seamheads.com's ballpark database reaches back to stadiums that were demolished generations ago — parks nobody alive today can actually walk into. Triptyka's checklist skips that entirely and sticks to the 30 ballparks you can visit right now in 2026, which is exactly why the two tools rarely compete for the same reader.
