Arga Labs
Real-world sandboxes for testing AI agents and agent-generated code. Arga spins up 'digital twins' of the services your software depends on — Stripe, Slack, Google Drive and more — that speak the same APIs, MCP tool calls and SDKs as production, so you can run thousands of test instances in parallel without touching real systems. YC 2026.

Our take
Real-world sandboxes for testing AI agents and agent-generated code. Arga spins up 'digital twins' of dependencies like Stripe, Slack and Google Drive that speak the same APIs, MCP calls and SDKs as production, so code and agents run against realistic services — thousands of instances in parallel — without touching the real thing. YC 2026 Demo Day standout.
Best for
Teams shipping AI-generated code or agents that need production-like test environments they can spin up fast.
Pros
- Digital twins of real services (Stripe, Slack)
- Same APIs, MCP calls and SDKs as production
- Thousands of parallel instances
- Tests agents safely before production
Cons
- Setup assumes a real dev workflow
- Twins approximate, not the real services
- Early-stage (YC 2026)
How it compares
Against generic CI sandboxes, Arga's edge is fidelity: twins that behave like the actual third-party services agents call, so tests catch real integration failures.
Full review
Arga Labs builds real-world sandboxes for agents and agent-facing software. AI lets engineers generate far more code, but it still has to be tested, and traditional sandboxes can't be created fast enough to keep up. Arga spins up 'digital twins' of a company's software so agents can safely test before code reaches production.
You deploy your code or agent into a sandbox that runs against replicas of external services like Stripe, Slack and Google Drive, with twins that support the same APIs, MCP tool calls and SDKs as the real software, and you can run thousands of instances in parallel. Arga was a standout from Y Combinator's 2026 Demo Day cohort.

Composio
Composio provides the execution infrastructure that connects AI agents to real software. It sits at the tooling and connectivity layer of the agent stack, giving developers one framework - SDKs, a CLI and 850+ pre-built connectors - to let agents act across apps such as GitHub, Slack and Salesforce. It handles the hard parts: complex authentication and OAuth, plus remote sandboxed environments for safe execution, exposed over the Model Context Protocol so agents can reason and then reliably take action. The platform is built for production, with SOC 2 and ISO 27001:2022 certifications and deployment across public cloud, VPC and on-premises. Composio operates from San Francisco and Bangalore and raised a $25M Series A led by Lightspeed, with angels including Vercel's Guillermo Rauch and HubSpot's Dharmesh Shah.
LiteLLM
LiteLLM, from BerriAI, is an open-source AI gateway that gives you a single OpenAI-compatible interface to 140+ providers and 2,500+ models, including OpenAI, Anthropic, Gemini, Bedrock, Azure, Mistral, Ollama and vLLM. You can use it as a lightweight Python SDK for direct calls, or deploy the proxy server as a centralized gateway for a team, with virtual keys, budgets, load balancing, rate limiting, request logging and LLM guardrails. It has become a default building block in the AI stack, with 45,000+ GitHub stars, 240M+ Docker pulls and over a billion requests served, and is used by companies including Netflix, Adobe and Stripe. The core is free; an enterprise tier adds JWT auth, SSO/SAML, audit logs, SLAs and dedicated support.
Claude Code
Terminal-based agentic coding tool from Anthropic for autonomous multi-step coding tasks.
Kiro
AWS agentic IDE built around spec-driven development: it writes a spec, then builds matching code, tests and docs across IDE, CLI and web.
