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.

Questions & Answers

As answered by people managing SVAR UI and Emisar.dev.

Why should a person choose your product over its competitors?

SVAR UI's answer

SVAR UI offers a set of complex, feature-rich UI building blocks, like calendar, Gantt chart, kanban board or data grid. Because SVAR components are framework-native, you avoid the boilerplate, compatibility issues, and performance overhead that come with wrapper-based libraries.

The components are optimized for large datasets and come with production-ready workflows out of the box โ€” drag-and-drop scheduling, in-cell editing, context menus, and built-in editors โ€” so you integrate in minutes instead of building forms and dialogs yourself. CSS-variable-based theming model makes customization straightforward across all three frameworks.

The free MIT-licensed core takes most projects far, the PRO edition covers advanced, enterprise-grade features.

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.

Which are the primary technologies used for building your product?

SVAR UI's answer

SVAR UI components are written natively in Svelte, React and Vue, and use CSS for styling.

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.

How would you describe the primary audience of your product?

SVAR UI's answer

Front-end developers and engineering teams building modern web applications in React, Svelte, or Vue who need complex, data-heavy, or scheduling interfaces โ€” data grids, Gantt charts, calendars, Kanban boards, and file managers. SVAR is especially well-suited to teams building project management tools, booking systems, logistics dashboards, and internal business apps who want framework-native components with TypeScript support, strong performance, and a low-config customization model rather than a wrapper library or a heavy all-in-one suite.

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.

What makes your product unique?

SVAR UI's answer

SVAR UI is built as native React, Svelte, and Vue components rather than framework wrappers, so each implementation works directly with its framework's rendering and state patterns. Every component ships with full TypeScript support, a rich API, an MIT-licensed core. Combined with virtualization, CSS-based theming, and localization built in, it delivers complex data, project management, and scheduling interfaces with minimal setup.

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. [

What's the story behind your product?

SVAR UI's answer

SVAR began with SVAR Svelte Core, an open-source library of form controls and essential UI elements, released in October 2023. Since then, it has grown to include advanced widgets like DataGrid, Gantt, File Manager, Calendar, Kanban, and more. In 2024-2025, React versions of the components were released, and in 2026 SVAR UI was extended with the Vue 3 version of the components. Also, Calendar and Kanban components were released in Svelte, React, and Vue versions.

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.

Who are some of the biggest customers of your product?
