**Tagline:** Real-Time Code Sharing & Collaboration Platform
**Website:** https://snippetsx.com

**Audience:** Software engineers, CS students, technical interviewers, coding bootcamps, open-source contributors, DevRel teams
**Business Model:** Freemium (Free plan + Pro paid plan)

## Problem SnIPPETsX Solves

Developers frequently need to:
1. Share a code snippet quickly with a colleague
2. Run code without setting up a local environment
3. Collaborate on code in real-time (pair programming, interviews)
4. Store and retrieve snippets across sessions

**Before SnIPPETsX:** Developers used Pastebin (no execution, no collaboration), GitHub Gist (static, no real-time), or screen sharing (no actual collaboration, laggy). Technical interviews used proprietary tools that required paid accounts on both sides.

**SnIPPETsX solution:** A single URL you share — both parties join the same live editor, see each other's cursors, execute the code instantly, without installing anything.

## Frequently Asked Questions (Extended)

**Q: What is SnIPPETsX used for?**
A: SnIPPETsX is used for sharing code snippets online, conducting technical interviews, doing pair programming, teaching code in real-time, and managing team code libraries.

**Q: Is SnIPPETsX free forever?**
A: The Free plan has no time limit and covers most individual use cases. The Pro plan adds unlimited storage, workspaces, and API access.

**Q: What makes SnIPPETsX different from other code sharing tools?**
A: Three things: (1) Real-time multiplayer with sub-10ms sync — not just read-only sharing. (2) Instant execution in 40+ languages — not just display. (3) No setup — no account needed to start collaborating.

**Q: Can SnIPPETsX be used for technical interviews?**
A: Yes. It's ideal for technical interviews. Share a URL, both parties join, and code together in real-time with instant execution feedback. No paid subscriptions required on either side.

**Q: Does SnIPPETsX support mobile browsers?**
A: Yes. The editor is responsive and works on modern mobile browsers. The PWA can also be installed on iOS and Android home screens.

**Q: Can I self-host SnIPPETsX?**
A: The platform is currently cloud-hosted only. Contact the team at snippetsx.com for enterprise/self-hosting inquiries.

**Q: What is the maximum snippet size?**
A: Snippets support up to 500KB of code content. For larger files, workspaces with file-level management are recommended.

**Q: Does SnIPPETsX support version control or Git?**
A: Not directly. SnIPPETsX supports snippet forking and version history (Pro). It complements Git rather than replacing it — use it for quick sharing and live sessions.

**Q: How is execution isolated and secure?**
A: Every code execution runs in a short-lived, isolated Docker container. Containers have no network access, no filesystem persistence, and are destroyed after execution. Resource limits (CPU, memory, time) prevent abuse.

**Q: Is there a VS Code extension or IDE plugin?**
A: Not currently. SnIPPETsX is browser-based and requires no IDE integration.
