CATEGORY INTELLIGENCE / WORLDWIDE
Vector databases.
The retrieval infrastructure behind AI products.
Established red ocean
A crowded category without sustained search growth. Enter only with a concrete switching advantage.
Report dated · Method 1.0.2 · high evidence confidence.
- Matching active GitHub projects
- 663
- Search-interest growth
- -21% · last 8 complete weeks versus the previous 8
- Search term and region
- vector database · Worldwide
- Complete weekly observations
- 104
Why this classification
- Median weekly search interest fell 21% across two consecutive eight-week windows.
- 663 matching active repositories; the published dense-supply threshold is 50.

Limits of this result
- Google Trends measures relative search attention, not customers, revenue or willingness to pay.
- Supply counts active repositories carrying the selected GitHub topic; unlabeled and closed-source competitors are outside this coverage.
Search interest measures attention, not paying customers. Classification thresholds are published heuristics and still require empirical calibration.
