Plex is your coding agent for building ambitious software.
Powered by world-class technology
Agent
Agents turn ideas into code
Describe the app. Plex scaffolds the full project: configs, routes, styles. Then it keeps iterating with you file by file while you make the decisions.

Command everything
Files, tasks, terminal and agents. Your entire workspace driven from one place. Memorise three shortcuts and never touch the mouse.
See all shortcuts
Every surface, one glance
Task cards, live editor, agent status, deploy terminal and metrics. A grid view of the whole project so you always know exactly where things stand.
From prompt to plan to code
Every task becomes an implementation plan with live progress, an agent narrating each step, and code plus terminal output updating underneath.
- ✓Define requirements
- ✓Create MissionControlView component
- Update window manager
- Implement expose logic
- Add multiplayer mode
Autonomy
Works autonomously, runs in parallel
Hand off a task and keep working. Cloud agents build, test and demo end to end: reasoning log, timeline and checklist included. They report back with a walkthrough.

Scale
Develop enduring software
Deployments, error rates, language usage and live agent workload. Observability for every agent, every repo, every hour. Secure per-user workspaces that scale with your team.
Explore enterprise
In every tool, at every step
Chat, dashboard, terminal, code review with agent comments, and metrics. Connected. Plex reviews PRs, flags vulnerabilities and keeps the whole loop in sync.
Frontier
Use the best model for every task
One request walks a fallback chain: Gemini, then Groq, then OpenRouter. A quota hit on one provider just means the next one answers, while fleets of agents work your repos in parallel.
Every project, one home
Dashboard, recents, active agent tasks and review states. Pick up exactly where you left off, in any project.
The new way to build software.
Ghost suggestions
Completions appear inline as you type, in any language the editor supports.
Full project scaffolds
package.json, configs, routes, styles and README. Never a loose component.
Live preview plus terminal
Boot the app in a WebContainer and watch output stream, right beside the code.
Free GitHub sync
Import any repo, export any project. No plan gates, ever.
Model fallback chain
Gemini, Groq and OpenRouter in one chain. Quota hit? The next provider answers.
Real file tree
Folders, renames, binaries and tabs. A project structure that actually builds.
Plex is an applied team focused on the future of software development.
We build the coding agent we always wanted. One that scaffolds whole apps, explains its work, and hands you something that runs.
