Laxmi Solutions is an independent product studio. We make 11 free web tools and 16 Android apps that open instantly, respect your privacy, and stay out of your way.
Featured products
Each product does one job exceptionally well — and runs in the browser or on your phone without a setup screen in sight.
A multi-file IDE that opens in a browser tab.
Write in 80+ languages on the same engine that powers VS Code. Preview Markdown, diff files, test APIs and run snippets — with your files kept on your device, not our servers.
Edit SVG visually and in code — at the same time.
A multi-file vector editor with node-level path editing and live two-way SVG code. Every change on the canvas updates the markup, and every markup edit flows back to the artwork.
A teleprompter that keeps pace with your voice.
Write or import a script and read hands-free. Voice tracking scrolls with how you actually speak, across languages, with camera recording and on-device storage built in.
Compile and judge code in 61 languages.
Run code against test cases on your phone with real verdicts — accepted, wrong answer, time limit and more. Every run executes on ls-judge in its own isolated microVM, across 114 language runtimes.
Turn WhatsApp chats into print-ready memory books.
Import an exported conversation and get a beautifully typeset PDF with photos, themes and keepsake stats. Parsing and rendering happen entirely in the browser — nothing is uploaded.
Platform · ls-judge
ls-judge is our self-hosted online judge and code-execution API. Every submission runs inside its own Firecracker microVM with an isolated network namespace, and per-test verdicts stream back live over WebSocket.

Firecracker microVMs
Each submission boots in its own Firecracker microVM with a private network namespace, seccomp and a jailer — never a shared container.
Warm snapshot pools serve popular languages in milliseconds; everything else restores from a cold snapshot on demand.
Verdicts, run time and memory for every test case stream back over WebSocket as they finish — no polling.

How we build
They shape what we build, what we refuse to build, and how each product treats the people who use it.
Wherever possible, your files are processed on your own device. Code, scripts, chats and drawings stay with you — we never need to see them to make the product work.
The essential features of every product are free, without sign-up walls. Optional upgrades exist only where they fund ongoing development — never to hold your work hostage.
Products open instantly on modest laptops and budget phones. We obsess over load time, smooth scrolling and large-file handling so the tool never gets in your way.
Every product has a focused job. We'd rather ship a smaller tool that does one thing well than a bloated one that pretends to do everything.
On Google Play
Native Android apps for automation, planning, documents, private messaging and learning — light, fast and offline-friendly.

The core of every web tool and Android app is free to use. A few apps offer optional upgrades or show ads to fund development, but the essential features never require payment or an account.
Our web tools are built to work in your browser: files you open in the code editor, Splice, Cueline or Chatcraft are processed locally on your device and are not uploaded to our servers.
No. You can open any web tool and start immediately. Products that sync or receive messages explain exactly what is stored and why.
16 products are available on Google Play, including the Online Code Editor, Splice, Cueline, Chatcraft, Reflex and Tend. You can find every app on our Google Play developer page.
ls-judge is our code-execution platform at runtimes.laxmi.solutions. It runs code in 65+ languages, isolating every submission in its own Firecracker microVM, and streams per-test verdicts live. Omni Compiler and the Online Code Editor both run code on it, and its free tier offers 500 executions / month · 60 requests / minute · playground with no sign-up.
Absolutely. Tools like DSA Visualizer, Omni Compiler, ScribbleMate and Curvy Kids are designed with classrooms and self-learners in mind. Get in touch if you'd like to use them with a group.
