Being an open-source alternative to any big incumbent isn't a surefire success. You need to reach at least feature parity with the existing tools in the market and then you need to out ship them. You want to become the clear successor to the incumbents, not just be an alternative that's also there.
Reach feature parity first, then out-ship incumbents to become the clear successor
Mark frames open-source competition as a two-stage race: match the incumbent on must-have features, then use community-driven velocity to surpass them. Stopping at parity leaves you a footnote; continuous shipping converts GitHub stars into switching momentum and eventually paying customers.
The biggest win is streaks. Believe it or not, we have our own way of counting streaks — the streak is represented by this small animated flame — and you can get beautiful opal gemstones when you reach different streak milestones. That's the biggest win in the last year to improve retention and growth.
Streaks outperformed every other retention feature Opal shipped in the last year
Schlenker names Opal's custom streak implementation as the single highest-impact retention feature of the past year. The streak counts cumulative focus sessions rather than simple daily check-ins, and the visual representation is a bespoke animated flame integrated with the Opal gemstone reward system. Users who hit streak milestones unlock new gemstones. The success is a reminder that well-established gamification mechanics still work when executed with craftsmanship and tied to genuine product behavior.
There's a play for whatever you're stuck on.
