Shells.com offers a virtual cloud computer that can be accessed from any web-enabled device. As we offer multiple Linux distributions or Windows preloaded on the virtual desktop, it gives the user the opportunity to use the operating system that they want on the device that they want. This is great for new users who would like to give Linux a test run without having to install on their hardware or for developers who would like to test and deploy all on one device. Schools and businesses can rapidly deploy computers and phones to those who need them at a low-cost.

Emisar is the last MCP server youโ€™ll need to install: a Zero-Trust gateway connecting Claude, Cursor, ChatGPT, and any AI agent to your infrastructure. One server handles production access, debugging, alerts, and internal operations, with new capabilities added as packs. Agents can inspect real production state, debug what they shipped, and help resolve incidents. Safe reads run automatically; policy allows, blocks, or routes risky actions for approval. No SSH keys, VPNs, remote shells, or standing shell access โ€” and every call is recorded.

Possible disadvantages of Shells

  • Dependent on internet connection
    Shells requires a stable and fast internet connection for optimal performance. Users with inconsistent or slow internet may experience lag or connectivity issues.
  • Recurring costs
    Using Shells involves a subscription-based payment model, meaning users must pay recurring fees to maintain access. This could be a con for users seeking a one-time purchase model.
  • Limited offline access
    Because Shells is cloud-based, users have limited functionality when they are offline, which could be disadvantageous for those needing constant access to their virtual desktops.
  • Potential security concerns
    Although Shells implements security measures, storing data in the cloud may still pose security risks, such as data breaches or unauthorized access, which may concern privacy-focused users.
  • Performance constraints
    Depending on the chosen plan and resource allocation, there may be performance limitations, particularly for users running resource-intensive applications compared to high-performance local machines.

Questions & Answers

As answered by people managing Shells and Emisar.dev.

How would you describe the primary audience of your product?

Emisar.dev's answer:

emisar is for SRE, DevOps, platform engineering, infrastructure, and security teams that want AI agents to inspect and operate production systems. It is especially relevant to teams managing multiple Linux hosts, clusters, databases, cloud services, or regulated environments where unrestricted shell access and incomplete audit records are unacceptable.

Which are the primary technologies used for building your product?

Emisar.dev's answer:

The hosted control plane and operator interface use Elixir, Phoenix, LiveView, PostgreSQL, and Tailwind CSS. The host runner and MCP bridge are written in Go. Action packs use YAML and JSON Schema, while production infrastructure is managed with Terraform on Google Cloud. The system communicates through MCP, OAuth 2.1, TLS, and WebSockets.

Who are some of the biggest customers of your product?

Emisar.dev's answer:

  • Blitz.gg - game analytics for billions of matches and a pretty large infrastructure.

What's the story behind your product?

Emisar.dev's answer:

Founder Andrii Dryga spent a decade working as a CTO, full-stack engineer, SRE, and DevOps engineer. He experienced the cost of running the wrong command on the wrong cluster, while also seeing AI solve operational problems in seconds. emisar grew from the need to preserve both truths: AI agents are useful, and production access must remain bounded. Its answer is to give agents a reviewed catalog of operations instead of a blank terminal.

What makes your product unique?

Emisar.dev's answer:

emisar lets AI agents work on real infrastructure without giving them a shell. Agents choose from a finite catalog of typed, versioned actions. Policy decides what runs, what requires approval, and what is denied, while an outbound-only runner verifies the action again on the host. New capabilities arrive as packs behind the same MCP integration, and every request is recorded in both a searchable audit trail and a tamper-evident host journal. [

Why should a person choose your product over its competitors?

Emisar.dev's answer:

Choose emisar when you want an agent to keep investigating and handling routine operations without handing it SSH credentials or supervising every call. Compared with raw shell access, copy-paste workflows, or one-off MCP servers, emisar provides reviewed action contracts, host-level enforcement, risk-based policy, scoped access, approvals, pack integrity checks, and a durable audit trail. It is built specifically for governed infrastructure access rather than generic automation.
