# Coasty — AI Employee Platform
# https://coasty.ai

> Coasty is the #1 ranked computer-using AI agent, scoring 82% on the OSWorld benchmark (369 real-world tasks). It controls a full desktop environment like a human — opening browsers, clicking, typing, filling forms, sending emails, and managing spreadsheets autonomously. Each session runs in an isolated sandboxed VM for security. Available as a web app, native desktop app (Mac & Windows), public REST API at `/v1/*`, and MCP server (`npx -y @coasty/mcp`). Starting at $19/month.

## What Coasty Does
- Autonomous computer control: browses the web, fills forms, sends emails, manages spreadsheets
- Browser automation: navigates websites, clicks buttons, extracts data, handles CAPTCHAs
- Desktop automation: controls any desktop application through screenshots and mouse/keyboard
- Terminal operations: runs commands, manages files, installs software
- Multi-agent orchestration: browser, desktop, and terminal agents work together on complex tasks
- File operations: read, write, edit, and manage files and directories
- Scheduled automation: cron, webhook, and email-triggered agent runs (HMAC-SHA256 signed)

## Key Differentiators
- #1 on OSWorld benchmark: 82% completion rate across 369 real-world tasks (state of the art)
- True VM-level isolation: every session gets its own sandboxed virtual machine — not shared containers
- Built-in CAPTCHA solving: works where other agents get blocked
- Multi-model support: works with OpenAI, Anthropic, Google, Mistral, xAI, Bedrock, and more
- Desktop app available for Mac and Windows (local machine control, no VM needed)
- Open-source framework: github.com/anthropics/open-computer-use
- Real-time streaming: watch the agent work live with full screen streaming
- Sandbox API keys (sk-coasty-test-*): free, mocked, identical schemas — perfect for CI

## Use Cases
- Marketing: autonomous Reddit campaigns, social media posting, content distribution
- Sales: prospect research, personalized email outreach, LinkedIn recruiting
- QA Testing: automated testing of web flows, bug detection and reporting
- Job Applications: finding roles, tailoring resumes, submitting applications
- Data Entry: form filling, spreadsheet management, CRM updates
- Customer Support: ticket resolution, account lookups, email responses
- Recruiting: LinkedIn sourcing, connection requests, interview scheduling
- Research: web research, data extraction, competitive analysis
