New Expensify is an open-source rebuild of the popular expense management app, redesigned from the ground up around chat and real-time financial collaboration between teams. Instead of treating expense tracking as a back-office chore, it weaves money management directly into conversations, making it feel more like a messaging app than traditional accounting software.

why it matters: With nearly 5,000 stars and over 2,300 contributors, this project signals that Expensify is betting its future on a chat-first, collaborative financial workflow — a direct challenge to legacy tools like Concur and even newer players like Brex or Ramp. For founders and PMs, it's a live case study in how an established fintech company is open-sourcing its core product to accelerate development and build community loyalty while repositioning against a rapidly evolving competitive landscape.

Blender is a free, professional-grade 3D creation tool that handles everything from building 3D models and characters to animating them, adding special effects, and rendering final visuals — all in one package.

why it matters: With nearly 20,000 stars and over 1,400 contributors, Blender has become the default 3D production tool for budget-conscious teams, making high-quality 3D content creation accessible without licensing fees that can run thousands of dollars per seat. For founders building in gaming, film, virtual reality, or AI-generated media, Blender's open-source pipeline and active ecosystem represent a cost-effective foundation for content production workflows.

why it matters: With over 5,500 forks, this project demonstrates massive grassroots demand for community-owned, moddable gaming experiences — a model that challenges traditional closed game publishing. For builders, it showcases how open-source infrastructure combined with passionate communities can sustain complex, long-lived interactive products without a commercial studio behind them.
