DexCode
co-r-e · Coding · Productivity
DexCode is an open-source AI slide authoring tool for developers. Instead of dragging boxes around a design app, you tell an AI coding agent like Claude Code, Codex, Gemini CLI, or Cursor to build the deck, and your slides render live in the browser as MDX files. It's also an AI slide generator for developers and a terminal presentation tool, so a developer slide deck stays next to your code. Think of it as an AI presentation generator you drive with prompts. The product was published under the name DexCode and renamed Amaroad in April 2026, so you'll see both names depending on where you look.
About DexCode
What Is DexCode
DexCode is a slide creation environment that treats presentations like source code. Slides live in your project as individual MDX files, and every edit runs through an AI agent rather than a mouse. The browser side is view-only. It previews and presents, but it never authors.
The problem it solves is context switching. Developers who need a presentation deck from the terminal usually stop coding, open a separate design tool, and rebuild their thinking there. DexCode keeps the whole thing in the terminal you're already working in, so a sprint summary or a pitch deck gets generated from the same workflow as the rest of your project. Why leave your editor at all?
The biggest limitation is also the point: there's no manual editing. If you want to fix a typo or nudge a color, you ask the AI to do it. Anyone who wants pixel-level control with a cursor won't like that. And since it's a developer tool, setup means cloning a repo and running a local dev server, not signing into a web app.
Getting Started
- Clone the repo with
git clone https://github.com/co-r-e/amaroad.git amaroad, then runpnpm installandpnpm run devto start the local server. - Open the preview in your browser at the local address the dev server prints.
- Point an AI coding agent at your deck folder and describe what you want, for example "create a pitch deck for my startup."
- Let the agent generate the MDX slide files, then watch them update in the live preview as each file saves.
- Refine with follow-up prompts, then present in presenter mode, export to PDF or PPTX, or share a live URL.

Key features
AI-First Authoring Workflow
Slides are always created and modified through an AI coding agent, never by hand. The web UI is strictly for previewing and presenting. That constraint is what makes the tool fast for developers, because the editing surface is the same terminal they're already in. No new tool to learn.
MDX Slide Files
Each slide is a standalone MDX file with full Markdown and JSX support, so decks live in version control alongside the rest of your project. You get diffs, history, and review workflows that plain binary presentation files never offer. It's text. It merges cleanly.
Parallel Slide Revisions
After the initial draft, you can assign one agent per slide and push multiple revisions at the same time. Review cycles shrink because edits don't queue up behind a single serial pass. Big decks get faster.
Built-In Components and Slide Types
Decks ship with 12 slide types, including cover, section, content, comparison, stats, timeline, and quote, plus more than 25 ready-made components and layouts. Charts, icons, code blocks, tables, math equations, and shapes are all available without building them from scratch.
Presenter Mode and Live Reload
A separate fullscreen window drives projector output, synced with the browser through BroadcastChannel. Hot Module Replacement keeps the preview current the moment any MDX file is saved. Save a file, see it. That's the loop.
PDF, PPTX, and Tunnel Sharing
Export a deck to PDF or PowerPoint from the browser, or expose it over the internet with a single click using Cloudflare Tunnel. Sharing a live URL lets teammates follow along or leave feedback without receiving a file first.
Built-In Image and Diagram Skills
The CLI can generate photorealistic images through Gemini or Codex and GPT's built-in image generation, along with professional SVG diagrams like flowcharts and architecture maps. Everything is styled to match the deck's theme automatically. No separate design pass needed.
Pros and cons
Pros
- Free and open source under the MIT license, so there's no subscription to evaluate before you try it.
- Keeps deck creation inside the terminal, which removes the context switch to a separate design app.
- Decks are stored as text files in Git, making versioning and collaboration far easier than with binary files.
- Parallel per-slide editing cuts the time spent on large revision rounds.
- Works with the AI agents developers already pay for, including Claude Code, Codex, Gemini CLI, and Cursor.
Cons
- No manual editing at all, so a one-character typo fix still requires a prompt to the AI.
- Setup means cloning a repo and running a local dev server, which rules out non-technical users.
- The project was renamed from DexCode to Amaroad, so older docs and bookmarks point to a different name and can confuse first-time users.
Frequently asked questions
Yes. DexCode is open source and released under the MIT license, so the tool itself costs nothing. You still pay for whatever AI coding agent you use to generate the slides.

DexCode Alternatives
Forefront
Forefront · CodingForefront is a web platform for building with open-source AI. It lets you fine-tune leading open-source language models on your own data, evaluate how they perform, and run them through an API or export them to host yourself. Developers who want the convenience of a closed-source platform but insist on owning their models and data are the target audience here.
Startkit
StartKit.AI · CodingStartkit is a boilerplate for building AI SaaS and AI wrapper products. Think of it as an AI startup boilerplate with the boring parts already wired up: authentication, Stripe and Lemon Squeezy payments, usage limits, transactional email, and an AI API starter that talks to OpenAI, Anthropic, Groq, or Llama. You clone the repo, set your price, and start on the part of your product that people actually pay for. It's Next.js under React and Tailwind, so most of the boilerplate code already feels familiar.
Testim
Tricentis · CodingTestim is an AI-powered test automation platform for building and running end-to-end tests across web, mobile, and Salesforce applications. It leans on machine learning to keep tests stable when an interface changes, so teams spend less time fixing broken selectors. Not bad for an automated testing tool you can start using today. You create tests by recording actions in a browser, then optionally add JavaScript when you need more control. It's a solid pick for busy QA teams.
