On pricing, Muse Spark (Meta) starts free while Devin requires a paid plan from day one ($20+). If you're testing the waters or running an occasional workload, that gap matters more than the score differential. Muse Spark (Meta) starts at $0; Devin starts at $20. Compare what each entry tier actually unlocks before you compare list prices -- the limits matter more than the headline number.

By use case: pick Muse Spark (Meta) when anyone who wants frontier-level ai for free. Pick Devin when development teams that want to offload well-scoped tasks like bug fixes, test writing, and boilerplate code to an autonomous agent. The two tools aren't fighting for the same person -- they're aiming at adjacent jobs that occasionally overlap. If you're squarely in Muse Spark (Meta)'s lane, the tier-list ranking and the use-case fit point the same direction; if you're in Devin's lane, the score gap matters less than the fit.

Bottom line: Muse Spark (Meta) is the better tool for most people right now. Pick Devin only when development teams that want to offload well-scoped tasks like bug fixes, test writing, and boilerplate code to an autonomous agent -- that's its lane, and inside that lane it still earns its place.
