Mediar

Capture a browser workflow once, then run it on demand against cloud VMs. Mediar records what you do in the browser, turns it into a reusable workflow, and executes it headlessly through MCP-driven virtual machines.

Live app: app.mediar.ai

Monorepo layout

Path	What it is
apps/web	Next.js 15 web app (dashboard, auth, billing, workflow management)
apps/desktop	Tauri desktop app (React + Rust) for capturing workflows
crates/executor	Rust workflow executor
modal_apps	Python executor deployed on Modal
packages/infra	Azure / telemetry utilities
supabase	Database schema and migrations

Architecture

GitHub workflows repo  →  Modal / Rust executor  →  MCP VMs  →  Supabase

Workflows are stored in a repo, dispatched to the Modal or Rust executor, run on MCP-controlled VMs, and results are persisted to Supabase.

Quick start

Requires Bun and Node 20 (see .nvmrc).

bun install
cp .env.example .env.local   # fill in your own keys
bun run dev                  # run all packages

Useful scripts:

bun run dev:web        # web app only
bun run dev:desktop    # desktop app only (Tauri)
bun run build          # build everything
bun run type-check     # typecheck all packages
bun run test           # run all tests

Deploy

# Python executor (Modal)
export PYTHONIOENCODING=utf-8 && modal deploy modal_apps/workflow_executor.py

# Rust executor
bun run deploy:rust        # dev
bun run deploy:rust:prod   # prod
