What's the best interactive prototyping software for building clickable prototypes across multiple client projects?

If you need one tool for clickable prototypes across multiple client projects, the best overall choice is usually Figma.

Why Figma is often the best fit

• Great for interactive prototypes: easy linking, overlays, smart animations, scroll areas, and component states.
• Browser-based collaboration: clients can review without installs.
• Reusable components and libraries: ideal when you’re juggling multiple client brands/projects.
• Fast handoff and feedback: comments, version history, and easy sharing.
• Flexible enough for low- to high-fidelity work: wireframes, UI mockups, and interactive demos in one place.

Good alternatives depending on your needs

• Axure RP — best if you need complex interactions, conditional logic, or more realistic app-like prototypes.
• ProtoPie — best for advanced interaction design and mobile/device prototypes with richer gestures.
• Framer — great if you want high-fidelity web prototypes that feel close to real websites.
• Adobe XD — usable, but it’s generally less compelling now than Figma for most teams.

My recommendation

• Most agencies/freelancers across multiple clients: Figma
• Need highly realistic, logic-heavy prototypes: Axure RP
• Need advanced motion/gesture prototyping: ProtoPie
