Generate 2x Presentation Mockups in Browser Memory
Wrap raw application screenshots in Safari chrome, desktop windows, and mobile frames. Uses client-side SVG foreignObject injection to produce crystal-clear retina exports with zero cloud latency.
Hue — Reverse-Engineer Color Palettes into Tailwind v4
Extract dominant color swatches using 2D Canvas logarithmic dominance scoring. Instantly export production CSS variables and native Tailwind v4 @theme configurations.
Type — Calculate Mathematical Modular Type Systems
Render harmonic typographic hierarchies via exact modular ratios. Test live responsive mockups directly against your machine's installed local font library.
Vector — Sanitize Raw SVGs into Clean Next.js JSX Components
Scrub Figma, Sketch, and Illustrator metadata namespaces. Clamp coordinate decimals for minimum byte size, and generate TypeScript-typed React components on the fly.
Zero-Server Developer Utilities
Compress media, generate cryptographic hashes, test regular expressions, and audit accessibility. Everything runs locally in browser memory.
Safely inspect JSON Web Tokens and generate SHA-256 fingerprints using hardware-accelerated browser cryptography. Never paste production credentials into random online tools.
Audit foreground and background pairings with live contrast ratio calculations. Simulate Protanopia and Deuteranopia using hardware SVG feColorMatrix filters.
Test complex pattern-matching algorithms in real time with high-contrast capture group breakdown and syntax highlighting powered by the browser's native V8 engine.
Generate multi-layer elevations applying mathematical easing curves to blur radii. Mimics natural optical light dispersion for modern UI depth.
Store code snippets, competitor screenshots, and design bookmarks in an indexed local vault. Ingests data seamlessly via companion browser extensions.
Client-Side WebP Compression & Metadata Scrubbing
Hardware-accelerated image compression running entirely within your browser. Shrink multi-megabyte PNGs and JPEGs down to fractional WebP payloads without sending a single byte to an external server.
Continuous Local Hard Drive Auto-Saves
Automates silent 15-minute background auto-saves directly to your chosen local folder using the native File System Access API. Your complete workspace data remains sovereign.
Sprint Velocity & Revenue Accounting
Run sprint boards, log billable hours without tab-suspension timer drift, and export client timesheets with zero subscriptions.
Flow — Drift-Proof Sprint Board & Time Tracking
Task management and billable client timers engineered with absolute UNIX timestamps to eliminate tab-suspension drift. Fractional-index midpoint sorting prevents expensive database refetches.
Orbit — Structured Positioning & Launch Copy Compiler
Assemble high-conversion launch copy for Hacker News, Product Hunt, and Reddit. Uses structured variable models to format release statements without writer's block.
Scale — Instant Multi-Resolution Asset Production
Batch crop and align brand graphics into OpenGraph banners, Twitter cards, and favicon formats simultaneously with hardware-accelerated canvas pan and zoom.
Tally — Itemized Billing & Proof-of-Work Reports
Reads client logs directly from Flow to assemble clean Markdown summaries and export standard CSV spreadsheets for accounting. Zero cloud subscriptions required.

Frequently Asked Questions
Everything you need to know about Lumist Studio's local-first architecture.
How can Lumist Studio be 100% free with no monthly subscriptions?
All 15 utilities execute directly on your local hardware, eliminating database servers, cloud compute clusters, and backend API processing costs. Zero cloud operational overhead allows us to offer the entire suite for free without renting your data back through monthly subscription paywalls.
Does anything get uploaded to a server?
Absolutely zero. Your mockups, color palettes, kanban boards, code snippets, and timesheets remain stored entirely inside your browser's sandboxed IndexedDB. We run zero analytics, zero user tracking, and zero remote storage servers. Your data never leaves your device.
Do I need an internet connection to use the suite?
An internet connection is required only when loading a tool for the first time. To protect your network bandwidth, the application does not force-download assets for all 15 utilities at once. Once a tool has loaded into browser memory, all image compression, color scraping, and document parsing run offline without transmitting network data.
Why do the browser extensions require permissions?
Our MV3 companion extensions utilize the activeTab permission model. Unlike extensions that demand broad, permanent host permissions across every website you visit, Lumist extensions read the active DOM only when you explicitly click their icon in your toolbar.
Can I lose my local data if I clear my browser cache?
Browser cache evictions can occasionally clear local storage. Lumist Safe eliminates this risk by utilizing the native File System Access API to perform rolling 15-minute background auto-saves of your workspace directly to a selected folder on your physical hard drive.
How can I verify that my data is genuinely staying on my local device?
Audit network traffic directly using your browser's Developer Tools (F12). Open the Network tab, compress an image, or run a regex match. You will observe zero outgoing HTTP payloads, zero telemetry pings, and zero third-party tracking scripts.
What happens if the browser clears my IndexedDB storage? Will I lose my work?
Modern browsers classify IndexedDB as persistent storage, but extreme disk pressure can trigger cleanup routines. Lumist Safe requests browser persistent-storage clearance and pairs it with rolling hard drive exports to guarantee your master workspace data remains safe and recoverable.
Does the local folder auto-sync feature (Lumist Safe) work on all browsers?
The native File System Access API is fully supported in Chromium browsers (Chrome, Edge, Brave, and Opera). For non-Chromium environments (Firefox, LibreWolf, and Safari) that restrict filesystem handles, Safe provides a one-click JSON master export so your data remains portable across devices.
