The Open Source category has been steady over the past 6 years of tracked data. Total launches went from 115 in 2021 to 136 in 2026.
Average engagement ratio across all Open Source launches: 0.20. Products above that line tend to solve a specific, painful problem. Products below it often entered a crowded space without clear differentiation.
Open Source peaked in 2025 with 334 launches. That was 1 year ago. The decline since then could signal market consolidation, saturation, or attention shifting to adjacent categories.
Average engagement per product dropped from 0.19 in 2021 to 0.16 in 2026. More products competing for the same attention pool. The community is spread thinner, which makes high-engagement launches more impressive.
The highest-performing quarter was Q2 2024, with an average interest score of 261 across 38 launches. Midday led that quarter.
1159 B2B launches (100%) vs 0 B2C (0%) across the full Open Source dataset. Open Source is heavily B2B. The products here target teams, companies, and professional workflows.

Volume without engagement is saturation. Engagement without volume is opportunity. Check which one you're looking at.
Sum of all interest scores in the quarter divided by number of products. Simple average. We don't weight by category or product age.
Depends on what's declining. If volume drops but engagement rises, the market is maturing. That's often good for existing players. If both drop, the category may be dying. The quarterly breakdown on each page tells you which pattern you're seeing.
At least three. Two data points is a line, not a trend. We have five years of data for most categories, which is enough to distinguish real shifts from noise.
Current year launches compared to the same period last year. Positive means more products launching. Negative means the category cooled. Neither is inherently good or bad. A mature category with fewer but better launches is often healthier than one flooding the market with clones.
Launch volume drops but engagement per product rises. Fewer builders entering, but the ones that do find a more receptive audience. That's an opportunity signal. We flag it when we see it.
We report what happened. We don't predict. Five years of data shows patterns, but markets surprise people for a living.
