Mextyl Code IDE is an autonomous software engineer — it plans your project, spins up specialized AI agents for architecture, UI, quant modeling and data, writes every file, validates and self-fixes the code, and deploys it to a permanent hosted URL — entirely inside your own Mextyl workspace.
Most AI coding tools finish a function. The Autonomous Engineer finishes the project — planning the architecture, assembling the right specialists, generating every file, and verifying the result before handing it back.
Every layer needed to go from a plain-English idea to a hosted, working financial application — without leaving Mextyl.
Describe your tool in plain English — the engine plans complexity, generates a full file structure, and builds every file end-to-end without manual coding.
Zero-Code BuildThe AI designs its own specialized agents per project — Architect, UI Designer, Financial Modeler, Quant Engine, Data Viz — each with a tailored expert prompt.
Every generated file is syntax-checked, structurally validated and automatically repaired — up to 3 fix attempts per file — before it's ever shown to you.
Deploy any project to a permanent, shareable Mextyl URL in seconds — no GitHub account, no separate hosting provider, no DevOps required.
Host Your Own ToolsEvery prompt is enriched with Mextyl's live MCP tool catalog — market data, CRM, Deal Room, LP Portal — so generated code calls real platform functions.
Switch between Claude Sonnet/Opus, Gemini Pro/Flash and GPT-5.6 on the fly — with automatic fallback to a lighter model if your primary choice is overloaded.
Monaco editor, file tree with drag-and-drop, branches, commit history, diff viewer, Git import/export, Pyodide Python runner — a real development environment.
REST client, SQL runner, regex tester, JSON tools, mock data generator, cron builder and more — a marketplace of dev utilities, no install required.
Not just single-file autocomplete — the AI Engineer sees your entire codebase, explains, refactors, fixes and reviews across every file in the project.
The AI first designs the exact team your project needs, then dispatches each file to the right specialist — no generic, one-size-fits-all output.
Every tool the Autonomous Engineer generates can go live in seconds — on infrastructure you already trust, without setting up a separate hosting account or fighting deployment configs.
Publish the active file with one click — get a permanent link for a demo, a client, or internal review.
Deploy the entire project — HTML, CSS, JS, data files — as one cohesive, permanently hosted website.
No third-party hosting, no GitHub account required — your tools and their data never leave your workspace.
Single-file preview, valid instantly, works from any device.
Publish the full multi-file project as one permanent site.
No TTL, no rebuild pipeline — the URL just keeps working.
WACC builder, debt schedules, exit sensitivity and IRR/MOIC waterfalls — generated with real formulas, ready for the AI to customize to your specific deal structure.
Describe a VaR or stress-testing methodology in plain English and get a working, hosted tool in minutes.
Spin up a bespoke screening dashboard for a specific sector or thesis without waiting on engineering.
Build a tailored waterfall or vintage-performance visualizer and share it as a permanent link with LPs.
Generate a portfolio attribution or correlation tool scoped exactly to your desk's workflow.
Use the built-in extensions — CSV viewer, SQL runner, mock data generator — for everyday data chores.
Let the Autonomous Engineer produce a working v1 fast, then review, edit and extend it in a real IDE.
Learn from the workflows, tips and best practices shared across our Learning Paths — curated from what our community reads the most.
Mextyl Code IDE is available today — describe your tool, watch it get built, and host it without ever leaving your workspace.
