developer-sandbox
Design interactive playgrounds that let developers experience your product without commitment and convert them into users.
What This Skill Covers
- Playground Design: Instant gratification, progressive complexity
- Pre-Populated Examples: Choosing examples that convert
- Sharing and Embedding: Shareable URLs and embeddable widgets
- Gating Decisions: When to require signup vs. keep open
- Conversion Optimization: Turning playground users into signups
- Architecture: Client-side vs. server-side playgrounds
When to Use This Skill
- Building a new developer playground
- Optimizing existing playground conversion
- Deciding what to gate vs. ungate
- Creating embeddable examples for documentation

Key Principle
A great playground removes uncertainty. Developers should be able to validate that your product solves their problem before investing in setup or signup.
Playground Levels
| Level | Experience | Goal |
|---|---|---|
| One-Click Demo | Click button, see result | Prove it works |
| Editable Input | Change input, see output | Build curiosity |
| Full API Access | Write code, call API | Demonstrate power |
| Full Playground | Build mini-app | Enable evaluation |
Quick Wins
- Pre-load a working example (not an empty editor)
