Execution platform for AI agents on Firecracker microVMs in the EU. Interactive Linux sandboxes with root, templates for Python, Node.js, Go, Rust and a headless browser, public HTTPS URLs. Background jobs that outlive the connection, batches of up to 1,000 jobs with dependencies, hard cost caps reserved up front, execution receipts with SHA-256, log digests that fit the context. IPv4, dual-stack or IPv6-only with its own public address, allowlists or no network. WASI runtime for small tasks. Idle sandboxes sleep and keep their files. Also REST API, Python SDK and LangChain.
Cuts coding agent token burn up to 72% continuously via contradiction-free memory & verification.
Agent utilities: read big pages without filling context, exact math, dates, parsing. Free.
Run sandboxed Python for calculations and PDFs; no other languages, installs or network.
Cloud iPhones and Macs with Xcode for AI agents: build, run and test iOS apps, use the screen.
Spin up a complete OpenCode development environment on any Linux box — one agent-driven workflow, six tools, zero secrets.
Expert know-how (kits) any AI can read or run, always the latest version.
Code mode (preview): the AI writes a script against a typed foundry.* API and runs it in a sandbox.
Proves AI-generated Python does what you asked: lint, types, security, sandbox run, exact fixes.
Universal pay-per-call tool API for AI agents. Web search, price feeds, hive memory, LLM routing, code sandbox. Free tier (10 calls/day, no signup). x402 payments on Base + Solana.
Hextrap's MCP Connector protects your LLM coding sessions from installing malicious dependencies, typosquats, unpopular packages, and enforces your strict allow and deny lists. No setup means your LLM uses MCP to configure itself to use Hextrap's proxy's automatically, enforcing your firewall rules immediately. Manage your allow and deny lists right from your favorite LLM.
Remote MCP server for Mythex, the AI app builder. Lets Claude, Cursor or Codex create projects in a cloud sandbox, edit files, run commands, preview, attach a database, and publish to a public URL. OAuth sign-in; tool calls need a Mythex Pro account.
I do everything related to coding and execution tasks
tasklite.net: hosted backend, REST API and admin for apps built by AI agents
Write, type-check and run AILANG in a sandbox, with Z3-proved contracts and docs search.
A browser 3D CAD for your AI: it scripts real-size models, uCAD builds them and returns pictures.
Let your AI assistant build a runnable Symfony 8, Laravel 13 or plain PHP 8.5 project and hand you a shareable link. The code runs in the browser with WebAssembly: no install, no account, nothing stored server-side (the code travels inside the link). Tools: get_starter (starting project, editable paths, Composer packages), create_sandbox (builds the link), read_sandbox (reads the code behind a link). Great for demos, answering questions with runnable code, or turning a bug from your project into
Proof and repair for Apple coding agents: validate Swift, run Xcode evidence, and repair failures.
Create shareable links to run Symfony, Laravel or plain PHP code in the browser, no install.
A free quantum job service: OpenQASM 3 run, checked and signed, with no account or key.
Run AI agent tasks in isolated sandboxes with a cost cap, saved workflows and scoped connections.
Low on memory? Your bot sends heavy jobs to cloud sandboxes on your own provider keys. Flat fee.
Create and preview self-contained web apps in iPhone, Duo, iPad, or Headless views. Seven starter tools and games, browser-local code saving, and HTML export. Free; no API key. Tools: open_ipadian, preview_app. Interactive previews require MCP Apps support. Independent web simulator; no native iOS apps or cloud sync. Setup and Claude/Codex downloads: https://os.ipadian.net/plugin/
One sentence to a finished animation: your AI writes motion graphics as code and checks real frames.
Hand routine JS/TS tasks to Codemind from your agent. $0.10 per verified build; failures are free.
Second opinion before an irreversible agent action; signed proofs, free verify, public ledger.
Pay-per-call MCP tools via x402 USDC: ZAR prices, data extraction, Python sandbox, SA flights.
38 MCP tools: Rust computation, Discovery, composition, counterexample scans and signed checks.
AI access to Quadratic spreadsheets: open files, run Python/SQL, query connected databases.
40+ developer tools from Context7, Code Runner, Python Execute, NPM Sentinel, PlantUML, and Microsoft Learn. Docs lookup, code execution, security scanning. Starts at $0.01/call. Get your API key at app.xpay.sh or xpay.tools
