The landscape of AI-powered development tools is experiencing a dramatic reshaping, with new data from SimilarWeb revealing significant shifts in market share over the past six months. The findings paint a picture of an industry in flux, where established players face mounting competition and emerging tools rapidly capture developer attention.
Cursor and Lovable Dominate the Field
At the top of the rankings, Cursor and Lovable have emerged as co-leaders, each commanding 28% of the market’s web traffic as of today. This represents a remarkable journey for both platforms, albeit through different trajectories.
Cursor has demonstrated steady, methodical growth, climbing from 26% six months ago to its current position. The AI-powered code editor has maintained consistency throughout this period, gaining just two percentage points but solidifying its position as a developer favorite.
Lovable, meanwhile, has experienced a more dramatic arc. The platform started six months ago with a commanding 35% market share—the highest of any single tool—before experiencing a correction that brought it down to 27% three months ago. Since then, it has stabilized and slightly recovered to match Cursor’s 28% today.
Coming in fourth is Replit, which has a 13% market share, up slightly from the 12% it had 6 months ago.
Perhaps the most striking story in the data belongs to Base44, which has achieved explosive growth over the past half year. Starting from just 1% of market share six months ago, the platform has surged to 11% today—representing an eleven-fold increase in traffic.
The trajectory tells a story of accelerating momentum: from 1% to 5% in the first three months, then doubling to 10% in the next month, and reaching 11% in the most recent period. This kind of hockey-stick growth suggests Base44 has struck a chord with developers seeking alternatives to more established platforms.
The Fragmented Middle
Beyond the major players, the market remains highly fragmented. Tools like Bolt, Windsurf, Tabnine, Cognition, and Arize collectively represent a significant portion of traffic, while an “All other” category captures numerous smaller tools vying for developer attention.
This fragmentation indicates a market still searching for definitive solutions, with developers experimenting across multiple platforms rather than consolidating around a single tool.
As the AI coding tools market continues to mature, the coming months will reveal whether current leaders can maintain their positions or if we’ll see further disruption from emerging platforms. For now, the message is clear: developers have embraced AI assistance, and the battle for their loyalty is intensifying.
