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.

Reactime features and specs

  • Time Travel Debugging
    Reactime provides a time travel debugging feature, allowing developers to simulate and observe how application state changes over time. This assists in identifying and resolving bugs more efficiently by stepping forward and backward through states.
  • State Management Visualization
    It offers a clear and intuitive visualization of a React application's state changes, making it easier to track and understand complex component interactions and state updates.
  • Performance Optimization Insights
    Reactime helps developers identify performance bottlenecks by providing insights into component rendering and re-render times. This information can be crucial for optimizing the application's performance.
  • Open Source
    Being an open-source tool, Reactime is freely available for developers to use and contribute to, promoting community-driven improvements and transparency.

Possible disadvantages of Reactime

  • Limited Framework Support
    Reactime is specifically designed for React applications, which may not be suitable for projects utilizing other frameworks such as Angular or Vue.js.
  • Learning Curve
    While providing powerful features, Reactime might have a steep learning curve for developers new to state management tools or those unfamiliar with its interface and functionalities.
  • Potential Performance Overhead
    When integrated into a complex application, Reactime might introduce some performance overhead, particularly if used extensively during development, which could affect real-time feedback and responsiveness.
  • Browser Extension Dependency
    Reactime relies on a browser extension for its functionality, which may not be convenient for developers reluctant to use additional tools or those who prefer integrated IDE solutions.

Questions & Answers

As answered by people managing Reactime 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.
