Modal alternatives in detail

  1. Daytona

    freemiumAGPL-3.0WebPlatform

    Daytona pivoted from dev-environment manager to agent infrastructure and found its market: sandboxes that start in under 90ms — isolated computers with dedicated kernel, filesystem, and network, lifecycle primitives, shared volumes, and agent tools — on Linux, Windows, or Android, with GPUs available. AGPL-3.0 self-hostable; cloud is usage-billed with signup credits.

  2. E2b

    freemiumApache-2.0WebPlatform

    E2B is the category-defining agent sandbox: Firecracker microVMs your agent spins up to run untrusted code — stateful Python/JS interpreters with rich outputs, full Linux terminals, package installs, pause/resume persistence, and a Desktop Sandbox for computer-use agents. SDKs and the production infra are Apache-2.0 (self-hostable); the hosted cloud is freemium with per-second billing.

  3. Vercel Sandbox

    freemiumApache-2.0WebPlatform

    Vercel Sandbox (GA January 2026) runs untrusted and AI-generated code in ephemeral Firecracker microVMs: millisecond startup, Node and Python runtimes with sudo, sandboxes persistent by default via automatic filesystem snapshots, up to 10,000 concurrent on Pro. The SDK and CLI are open-source Apache-2.0; Hobby gets a real free monthly allotment, Pro is usage-billed.

  4. Baseten

    freemiumPlatform

    Baseten runs ML and LLM models in production: package serving logic with the open-source Truss framework, push it, and get an autoscaling GPU endpoint. It handles containerization, multi-region/multi-cloud replicas, scale-to-zero, and per-deployment observability — built for serving your own and open-source models at production scale.

  5. fal

    freemiumPlatform

    fal is a generative-media platform and inference cloud built for running diffusion models — image, video, audio, and 3D — fast. It exposes 1,000+ ready models through a single API with client SDKs, plus custom training and private deployments, billed pay-per-use. Its proprietary Inference Engine targets media generation rather than LLM text serving.

  6. Replicate

    freemiumPlatform

    Replicate is a hosted platform for running open machine-learning models — LLMs, image, video, audio, and more — behind a single API, billed per second of compute. Thousands of community models run with one line of code, and you can package and deploy your own using Cog, its open-source container tool. Replicate joined Cloudflare in 2025.

  7. Unsloth

    open sourceApache-2.0Linux, WindowsSDK

    Unsloth is an open-source library (Apache-2.0) that makes LoRA/QLoRA fine-tuning of open-weight LLMs roughly 2x faster and far lighter on VRAM via hand-optimized kernels, so fine-tunes run on a single consumer GPU or free Colab. It integrates with Hugging Face TRL/PEFT and supports Llama, Mistral, Qwen, Gemma, Phi, and other popular architectures.
