Modal
Modal is a serverless platform for running AI and data workloads in the cloud without managing servers. You write ordinary Python, add a decorator, and Modal runs it on demand across CPUs or GPUs, scaling from zero to thousands of containers and back, which suits inference, batch jobs, fine-tuning, and background processing. Developers like it for fast cold starts and a clean local-to-cloud workflow, and it bills by the second with no egress fees or storage charges. There's a free starter tier with monthly credits, a team plan, and GPU rates spanning older and current cards. Modal reached unicorn status in 2025 and raised a large round in 2026 as demand for AI compute kept climbing. It's a developer tool rather than a no-code product, and production guarantees and certain regions carry cost multipliers worth modeling before you commit.

Our take
Modal runs AI and data workloads serverlessly: write Python, add a decorator, and it scales across CPUs and GPUs with fast cold starts and per-second billing. A free tier, no egress fees, and a clean developer experience make it a favorite for inference and batch jobs. It's developer infrastructure, and production or region multipliers affect real cost.
Best for
Developers who want to run inference, fine-tuning, or batch jobs on serverless GPUs from plain Python without managing infrastructure.
Pros
- Run Python on serverless CPUs and GPUs with a decorator
- Fast cold starts; scales to zero
- Per-second billing with no egress or storage fees
- Free starter tier with monthly credits
Cons
- Developer tool, not a no-code product
- Production workloads carry a cost multiplier
- GPU compute still gets expensive at scale
How it compares
Where Baseten and Fireworks focus on serving models, Modal is general-purpose serverless compute - any Python workload, not just inference - which makes it more flexible but less turnkey for pure model APIs.

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.
