## Archal

Archal targets the messy reality of integration testing for AI agents. Agent workflows call many third-party APIs in sequence, and real test accounts bring rate limits, shared mutable state, and flaky results. Archal replaces those accounts with sandboxes: time-bounded runtimes containing one or more stateful environments. Each environment mimics the paths, methods, payloads, and response shapes developers already know, retains mutations for the life of the sandbox, and can be reset to a declared baseline so every test run starts from the same known state.

A sandbox can hold multiple environments at once, and a single Archal API key manages all of them through one gateway. That makes it practical to give each CI job or feature branch its own sandbox, to keep test runs isolated from one another, and to run reinforcement-learning or agent-training rollouts where each episode must begin from an identical starting point while changes persist through the episode. Archal also ships a guided skill that connects Claude Code, Codex, Cursor, or Devin to the environment catalog via a single npx command, so coding agents can provision their own sandboxes.

Environments are Archal-managed simulations, not the providers' live services, and the company documents each environment's capability profile and exceptions rather than claiming blanket upstream parity. Pricing is usage-based: $0.10 per environment-minute, billed by the second, with failed provisioning and cold-start time free, and $20 in starter credits ($5 after verified signup plus $15 when the first sandbox is ready).

**Pricing & Plans:** Usage-based with a free starting allowance: $5 in credits after verified signup and $15 more when your first sandbox becomes ready, then $0.10 per environment per minute, prorated by the second. No card required to start; failed provisioning and cold-start time are not billed. Paid continuation tiers are being rolled out gradually.

- **Stateful simulated environments:** Spin up environments for GitHub, Slack, Stripe, Linear, Supabase, Datadog, HubSpot, Jira and more that persist mutations during a run and reset to a declared baseline on demand.
- **REST and MCP interfaces:** Call environments through familiar REST paths and payloads or through MCP tools, so existing agent code and tool definitions work with minimal changes.
- **One key, many sandboxes:** A single API key creates and manages every sandbox and environment, with shared gateway routing while each environment keeps its own endpoint and readiness state.
- **Multi-environment sandboxes:** Combine every environment a workflow needs into one sandbox, giving each its own readiness state and endpoint so end-to-end agent flows can be tested together.
- **CI, branch and RL isolation:** Give each CI job, branch, or RL rollout its own sandbox with an identical starting state — ideal for harness testing, integration testing, and agent training.
- **Setup skill for coding agents:** Install with one npx command and let Claude Code, Codex, Cursor, or Devin verify access to the full environment catalog before you write any application code.

**Strengths:** Eliminates test-account headaches such as rate limits, shared state, and flaky third-party dependencies.; Familiar REST and MCP surfaces mean existing agent code often works with little or no change.; Second-level billing with free credits and no card required keeps experimentation cheap.; Sandbox reset gives reproducible test runs, which is hard to achieve against live APIs.

**Limitations:** Environments are Archal-built simulations, so behavior may not match every edge case of the real provider.; Paid continuation options are still rolling out, which limits options for long-running production use.

## Modal

Modal provides cloud infrastructure aimed squarely at AI and data teams. The core idea is that developers write ordinary Python, decorate functions or define container images, and Modal takes care of the underlying compute: scheduling containers, attaching GPUs, autoscaling from zero and back, and exposing endpoints over HTTPS. Infrastructure concerns like networking, storage, and capacity management are abstracted away, so a workload that runs on a laptop can run the same way across a fleet.

The platform is organised around a few primitives. Functions handle serverless compute and can fan out across thousands of GPUs for parallel or batch work. Sandboxes provide isolated environments for coding agents, reinforcement learning rollouts, and other untrusted code, with sub-second start times and support for very high concurrency. Training covers fine-tuning, reinforcement learning, and evaluation on single or multi-node GPU capacity. On the inference side, Modal offers OpenAI-compatible endpoints for open-weight models and lets teams deploy custom stacks and tune endpoints to match their traffic shape.

Underneath, Modal runs its own container runtime and image system designed for large images and fast GPU scheduling, along with a distributed filesystem for fast access to model weights and datasets. Capacity is drawn from a multi-cloud pool spanning many regions, with automatic routing to available hardware and continuous fleet health checks. Billing is usage-based, charged by the second while code runs, with granular cost controls. The company offers a free starting allowance and scalable paid usage, and markets to enterprises with SOC 2 Type II compliance and HIPAA readiness.

**Pricing & Plans:** Modal uses usage-based pricing billed by the second: a free monthly compute allowance gets you started, then you pay for the CPU, memory, and GPU resources your workloads consume. Enterprise plans and startup credits are available, and custom pricing can be discussed with sales.

- **Serverless Python functions:** Write plain Python, attach GPUs or containers, and deploy HTTPS endpoints that autoscale with traffic and scale to zero when idle.
- **Sandboxes for agents:** Launch isolated, secure environments for coding agents, RL rollouts, and untrusted code, with sub-second starts and support for over a million concurrent sandboxes.
- **Training and fine-tuning on demand:** Run fine-tunes, LoRA, full training, and reinforcement learning on elastic single or multi-node GPU capacity with no quota requests.
- **Model inference and endpoints:** Serve LLMs and image, video, or audio models through OpenAI-compatible endpoints, or bring your own inference stack and let Modal handle the infrastructure.
- **Fast storage and multi-cloud capacity:** A distributed filesystem loads large images and model weights at full bandwidth, while a pool spanning 20+ clouds routes workloads to the right hardware and region.

**Strengths:** Python-native developer experience with almost no infrastructure boilerplate; Scales from zero to thousands of GPUs with per-second, usage-based billing; Sandboxes are well suited to agentic and untrusted-code workloads; Multi-cloud capacity spans many regions with out-of-the-box observability and enterprise compliance

**Limitations:** Billed by real usage, so heavy GPU workloads can get expensive quickly without cost controls; Some advanced inference and enterprise features require working with the team rather than self-serve signup; The serverless model can feel less familiar to teams used to managing their own VMs or Kubernetes clusters
