Chessigma reaches about $7.2K MRR on TrustMRR

Chessigma is showing about $7,228 in monthly recurring revenue and $65,998 in all-time revenue on TrustMRR, which says the figures are verified with a Stripe API key. The startup’s page also shows 568 active subscriptions and $20,278 in revenue over the last 30 days, while describing the product as "Chess.com but free" and saying it has "1M+ users."

TrustMRR says Chessigma is a free chess analyzer that runs on the user's device, offers unlimited game reviews with full Stockfish analysis and has no premium tier. The page also says the product targets chess players using Chess.com and Lichess, lists pricing as free and marks the company as open source. Its stack includes Next.js, Supabase, Vercel and Stripe.

Founder Mehdi Ben Haddou described the product’s technical design in more detail in a Sept. 26 DEV Community post. He said Chessigma started in March 2025 after players complained about limits on free game review. He added that the chess engine is compiled to WebAssembly and runs in the browser tab on the user’s own device, while the server fetches games, computes some statistics at the end and stores the result.

Ben Haddou also reported that Chessigma was handling more than one million reviews a month as of Sept. 26. On X, he separately self-reported that Chessigma hit €5,000 in MRR that day. Those figures are lower than the $7,228 MRR shown on TrustMRR, but both sources point to a startup with growing usage and revenue.

How does Chessigma’s product work?

Chessigma’s core mechanic is that the chess engine itself runs in the browser rather than on a central backend. Ben Haddou said the engine is compiled to WebAssembly, which lets the analysis run on the user’s own device. In his account, the server’s role is narrower: it fetches the game, performs some stats computation and stores the result.

That split is central to the product’s setup, according to Ben Haddou and TrustMRR. TrustMRR says Chessigma offers full Stockfish analysis without daily limits or a premium tier, and that its pricing is free. Ben Haddou also said the product grades each move from "Sigma" down to "Clown," and that the labels followed a trademark conversation with Chess.com.

What do the revenue and usage figures show?

The clearest outside revenue snapshot comes from TrustMRR. Its startup page lists about $7.2K in MRR, $65,998 in all-time revenue and 568 active subscriptions. TrustMRR also shows $20,278 in revenue over the last 30 days and says the revenue was verified with a Stripe API key.

Those figures are higher than Ben Haddou’s Sept. 26 self-reported milestone of €5,000 in MRR. They also sit alongside his claim that the service was processing more than one million chess reviews per month as of that date. TrustMRR’s founder page also attributes $65,998 in total revenue and $7,228 in MRR across Ben Haddou’s startups, with Chessigma identified as the revenue-generating business.

What is known about the founder and company?

TrustMRR says Chessigma was founded in March 2025 and is based in Belgium. Ben Haddou’s X profile identifies him as the founder of chessigma.com and says he previously worked at Booking.com and Amazon.

Ben Haddou’s DEV Community post says the startup was born from frustration over limits on free analysis, and his public updates suggest the company is still iterating on the product’s infrastructure. He wrote that Chessigma moved static assets including JavaScript, CSS and the engine to a CDN on a separate domain in April, and later added a beacon after seeing roughly 150 page loads a day arrive without CSS, with iOS Safari heavily overrepresented.

He also said a watchdog fix was needed for mobile stability. Before that fix, he wrote, the watchdog fired about 3,100 times in 14 days and the median interrupted run was 48.66% complete. In the mobile app, where the watchdog was enabled, 39.8% of users hit at least one failed analysis in that two-week period, almost all on Android. Ben Haddou added that Cloudflare cached 404s at the edge for four hours.

Chessigma’s public metrics show $7,228 in MRR, $65,998 in all-time revenue and 568 active subscriptions on TrustMRR, alongside a product that runs its Stockfish-based engine in the browser and handles game retrieval, stats and storage on the server. The company’s public materials and founder updates point to a free chess-analysis service that is still evolving operationally.
