Browse Without an Account
Search & Filter
Search across all instructionals by title, instructor, or category. Filter by technique area to find exactly what you need.
Read Reviews & Ratings
See what the community thinks before you buy. Every instructional shows its average rating and written reviews.
Compare Side-by-Side
Can't choose between two instructionals? Use the Compare tool to see ratings, price, and details head-to-head.
Check Price History
Every instructional page shows price history. Know whether that "50% off" is actually a good deal or just permanent marketing.

- Say whether the production quality and instruction clarity was good
- Be specific about what worked or didn't work for you on the mats

FAQ
Is GrappleDB free?
Yes, completely free. No premium tier, no paywalls. Browsing, searching, comparing, reviewing, and creating lists — all free.
Where does the data come from?
Instructional data (titles, descriptions, prices, images) is sourced from BJJ Fanatics. Ratings and reviews are from the GrappleDB community — real grapplers sharing their honest opinions.
Can I edit or delete my review?
Yes. Go to the instructional page where you left a review. You'll see an "Edit Your Review" button if you're logged in. You can also delete your review using the delete button on your review.
How are instructor ratings calculated?
Instructor ratings use a Bayesian weighted average. This means an instructor with one 5-star review won't outrank someone with dozens of 4.7-star reviews. The more reviews an instructor's instructionals have, the more their rating reflects actual quality rather than small sample luck.
Is GrappleDB affiliated with BJJ Fanatics?
No. GrappleDB is an independent, community-driven project. We catalog and index instructionals to help grapplers make informed purchasing decisions, but we are not affiliated with, endorsed by, or connected to BJJ Fanatics in any way.
I found a bug / have a feature request
GrappleDB is actively being developed. If you find something broken or have an idea for a feature, let us know on Reddit or through the community channels. We're building this for grapplers, by grapplers.
