## Composio

Composio sits between your AI application and the outside world. Instead of hand-coding an integration for every SaaS product your agent needs, you pick from a large catalog of pre-built toolkits, and Composio handles the tedious parts: OAuth authorization, credential storage and refresh, per-action permission scopes, and execution. The same catalog powers both agent frameworks (via SDKs and function calling) and MCP-compatible clients such as Claude, ChatGPT, Codex, and Cursor, which can connect through a single managed MCP endpoint.

The platform has expanded well beyond simple tool calling. Triggers let agents start background work in response to events in connected apps. Firewall inspects tool results and blocks hidden prompt-injection instructions before the model reads them. Instant tools provide audio, video, search, browser, and data capabilities without managing your own API keys, and optimization features aim to lower the cost per completed task. Enterprise controls add SSO, governance, and audit trail support.

The product is aimed primarily at engineering teams building agents or agentic backends, and secondarily at knowledge workers who want Claude or ChatGPT to operate their everyday apps. It follows a freemium model with a free developer tier and paid tiers plus custom enterprise agreements, and the company states SOC 2 Type II compliance.

**Pricing & Plans:** Freemium. A free developer tier is available for getting started, with paid plans and custom enterprise pricing for higher usage, team controls, and security requirements. Exact tier limits are published on Composio's pricing page; contact sales for enterprise terms.

- **1,700+ app toolkits:** A large catalog of pre-built integrations spanning productivity, CRM, support, engineering, finance, HR, and e-commerce apps, each exposing callable actions to your agent.
- **Managed authentication:** Composio runs OAuth flows, stores and refreshes credentials, and enforces per-action permission scopes so agents act only where you allow them.
- **MCP gateway:** One managed MCP endpoint that connects Claude, ChatGPT, Codex, Cursor, and other MCP clients to your entire tool catalog in a few clicks.
- **Triggers:** Start background agents from events occurring across connected apps, so work can begin without a user prompt.
- **Firewall and enterprise governance:** Inspect tool outputs to block injected instructions, and add SSO, audit trails, and org-wide policy controls for regulated deployments.

**Strengths:** Very large integration catalog, which removes most custom API glue work; Handles the hard parts of auth: OAuth, token refresh, and scoping; Works with both code-first SDK flows and no-code MCP clients; Safety features such as Firewall and enterprise governance are uncommon in this category

**Limitations:** Deeper capability comes with a learning curve around toolkits, actions, and auth configs; Free tier limits are modest, so production use generally requires a paid plan; Behaviors and available toolkits change frequently, so docs must be checked often

## Nebius

Nebius positions itself as "the ultimate AI cloud," an infrastructure stack engineered specifically for AI workloads rather than adapted from general-purpose cloud. The core of the platform is raw GPU capacity from NVIDIA — including GB300 NVL72, HGX B300, GB200 NVL72, HGX B200, H200, H100, RTX PRO 6000, and L40S — delivered as non-virtualized instances attached to InfiniBand networking. Above that sit managed services such as Kubernetes, Soperator (Slurm on Kubernetes), PostgreSQL, and MLflow, so teams get the orchestration and experimentation tooling that large training runs need without assembling it themselves.

On the inference side, Nebius offers Token Factory, a managed endpoint for running open and frontier models, alongside serverless compute options. Storage is available as shared filesystems, WEKA, block volumes, and tiered object storage, all priced transparently by the gigabyte. Consumption is flexible: customers can pay on-demand, use preemptible and spot capacity at market-driven prices, or reserve capacity through commitments for lower rates. Networking egress, public IPs, and Kubernetes management are listed as free, which simplifies capacity planning.

Nebius supports the full lifecycle — pre-training, post-training, and inference — and publishes customer stories spanning financial services, healthcare, robotics, media, and e-commerce. Because the company also operates its own data centers and hardware supply chain, it can offer capacity guarantees and support arrangements that are hard to match on repurposed public cloud. Pricing is usage-based and published on the site, with contact needed for large clusters and enterprise agreements.

**Pricing & Plans:** Usage-based pricing published on the site. On-demand GPU instances range from roughly $1.55/GPU-hour for L40S up to about $9.50/GPU-hour for HGX B300, with preemptible and live spot options starting around $0.79/GPU-hour. CPU-only instances start near $0.06/cpu-hour, managed Kubernetes and networking are free, and large-scale clusters or commitments are quoted through sales.

- **Non-virtualized GPU clusters:** Bare-metal access to NVIDIA GB300, B300, GB200, B200, H200, H100, RTX PRO 6000, and L40S GPUs connected over InfiniBand for training and inference at scale.
- **Nebius Token Factory:** A managed inference service for running popular open and frontier models through an API, so applications can add LLM capabilities without owning GPUs.
- **Managed MLOps services:** Built-in Kubernetes, Soperator for Slurm jobs, PostgreSQL, and MLflow give teams a ready-made environment for orchestration, tracking, and experiments.
- **Flexible consumption and spot pricing:** Choose on-demand, preemptible, or live market-driven spot capacity, or commit to reserved clusters for discounts on long-running workloads.
- **Scalable AI storage:** Shared filesystems, WEKA, block volumes, and tiered object storage sized for multi-hundred-terabyte training datasets.

**Strengths:** Transparent, publicly listed per-hour GPU and storage pricing; Broad NVIDIA lineup from L40S up to GB300 NVL72; Free Kubernetes management, networking egress, and public IPs; Integrated MLOps tooling including MLflow, Slurm via Soperator, and PostgreSQL

**Limitations:** Top-end clusters like GB300 and GB200 are quote-only, not self-serve; Spot and preemptible capacity is interruptible and prices move with demand; Requires meaningful ML infrastructure knowledge to get the most out of it
