Ask HN: How do you prevent sensitive data leaks in screen-recorded demos?
I nearly exposed user data in a product demo and started using a strict pre-record checklist.
My current workflow: 1) use demo-safe seed data 2) identify sensitive fields before recording 3) apply blur/mask before hitting record 4) refresh once to verify persistence 5) run a 30-second dry run
This reduced both editing time and stress.
Curious what workflows/tools people here use for screen recording privacy (especially for SaaS demos and tutorials).

Show HN: MCP-X – Single-file multi-client MCP gateway with per-tool access ctrl
We built a lightweight gateway (one Python file) that lets multiple AI clients share MCP tool servers with fine-grained, per-tool access control via fnmatch patterns. Config is a single TOML file with live reload.
It works like a file-based proxy - point your agent at the static gateway URL once, then dynamically connect and swap out actual MCP servers behind it at any time via changing config file / REST API. No need to reconfigure your agents when your tools change.

Show HN: Rawkit – Free, no-ads developer tools that run in the browser
Hey HN,
I built rawkit.dev, a collection of browser-based developer utilities. No ads, no signups, no tracking. Everything processes client-side — your data never touches a server.
The tools:
- JSONForge: JSON editor with tree/graph views, diff, transform, JQ-style queries, format conversion
- SQLSandbox: SQLite via WASM — import CSVs, write SQL, join across files
- Regexplorer: Regex builder with live matching, plain English mode,nmulti-language export
- SiftLog: Log file viewer with auto-detection, severity filtering, regex search, timeline
- Tabulate: CSV/TSV viewer with spreadsheet-style filtering and sorting
Tech: Vanilla HTML/CSS/JS. No frameworks, no build step.
Each tool is essentially 3 files(index.html, css and .js file)
I built these because I was sick of ad-ridden, upload-your-data-to-our-server alternatives for tasks I do daily. The goal is to keep adding tools that developers actually need.
Curious what tools you'd want to see next

Show HN: A free online British accent generator for instant voice conversion
I've developed a simple AI-powered British accent generator. Enter or paste your text, select the voice that best fits your project's tone, and generate speech for free. It supports up to 500 characters and offers 8 distinct, lifelike voices. Everything runs entirely within your browser. I'm primarily seeking feedback on output quality, user experience, and any technical improvements worth exploring.
