Google A2UI: The Future of Agentic AI for DevOps & SRE (Goodbye Text-Only ChatOps)
Source: Dev.to

The era of “Text‑Only” ChatOps is ending. Google’s new open‑source protocol, A2UI, lets AI agents render native, interactive interfaces. Here’s what Platform Engineers and SREs need to know.
🚀 TL;DR (For the Busy Engineer)
-
What is it?
A2UI (Agent‑to‑User Interface) – an open‑source standard from Google that lets AI agents generate UI components as JSON instead of raw text or HTML. -
Why care?
It eliminates the “wall of text” problem in ChatOps. Agents can now surface interactive forms, charts, and buttons directly inside your chat application or internal portal. -
Key tech:
Declarative JSON payloads that are safe like data yet expressive like code, removing the need for arbitrary JavaScript execution. -
Use cases:
Ideal for SRE Incident Response, MLOps Labeling, and Self‑Service Infrastructure.
The Problem: The “Wall of Text” Bottleneck
We’ve all been there. It’s 3 AM, you’re responding to a P1 incident, and you query your Ops bot:
@ops-bot status service-payments
The bot replies with 50 lines of unformatted JSON logs. To fix the issue you must:
- Remember the exact CLI syntax.
- Type it out manually.
- Hope you didn’t typo a region flag.
This is the “Last Mile” problem in AI‑driven operations. Brilliant LLMs can diagnose complex Kubernetes issues, but they are forced to communicate through dumb text channels. The friction increases cognitive load and slows Mean Time To Resolution (MTTR).
Enter A2UI: “Safe Like Data, Expressive Like Code”
Google released A2UI to bridge this gap. Unlike previous approaches that relied on heavy iframes or dangerous raw‑HTML injection, A2UI uses a standardized JSON schema.
How it works
- The Agent analyzes the request and sends a JSON “blueprint.”
- The Client (your web portal, mobile app, or chat interface) receives the JSON.
- The Renderer converts that JSON into native components (React, Flutter, Angular, etc.) that match your brand’s style system.
Why This Architecture Wins for DevOps
- Security First – The agent cannot execute code. It can only request components (e.g.,
Card,Button,Graph) that exist in your client’s allow list. - Native Feel – The UI looks and behaves like your internal developer platform, not a disjointed third‑party embed.
- Bi‑Directional Sync – Clicking “Restart Pod” updates the state instantly in the UI without a page refresh.
Some Use Cases for Platform Teams
If you’re building an Internal Developer Platform (IDP), here’s how you can use A2UI today.
1. Interactive Incident Commander (SRE)
Instead of linking to a Grafana dashboard, the agent generates the dashboard in the conversation.
| Trigger | A2UI response |
|---|---|
| “Alert: High latency on checkout.” | An interactive Card containing: • 📉 Visual: Live mini‑chart of error rates (last 15 min). • 📝 Context: Summary of the last three deployments. • 🔴 Action: “Rollback” button that triggers a specific GitHub workflow. |
2. Human‑in‑the‑Loop MLOps
MLOps teams often struggle with “edge cases” where a model has low confidence. Building a custom web app for labelers is expensive.
| Scenario | A2UI solution |
|---|---|
| A fraud model flags a transaction with 45 % confidence. | The agent pushes a “Review Card” to the Ops channel. Content: Transaction metadata + user history. Input: [Confirm Fraud] vs. [False Positive] buttons. Outcome: The click labels the data and triggers a fine‑tuning job instantly. |
3. Self‑Service Infrastructure Provisioning
Stop making developers write Terraform for simple resources.
| Request | A2UI response |
|---|---|
| “I need a Redis instance for staging.” | A dynamic form appears: • Dropdown: Select environment (Dev / Stage). • Slider: Select TTL / retention. • Validation: The agent validates quota before the user clicks Submit. |
The Code: Anatomy of a Payload
For developers, here’s what the actual wire protocol looks like. It’s incredibly readable:
{
"component": "Card",
"title": "⚠️ Production Alert: High CPU",
"children": [
{
"component": "Text",
"content": "Service 'payment-gateway' is at 98% utilization."
},
{
"component": "Row",
"children": [
{
"component": "Button",
"label": "Scale Up (5 Nodes)",
"action": "scale_up_action",
"style": "primary"
},
{
"component": "Button",
"label": "Snooze Alert",
"action": "snooze_action",
"style": "secondary"
}
]
}
]
}
This JSON is platform‑agnostic. Your React frontend can render it as a Material‑UI card; your iOS app can render it as a native SwiftUI view.
A2UI vs. MCP vs. Standard ChatOps
For those comparing this to Anthropic’s MCP (Model Context Protocol) or classic webhooks, here’s a quick breakdown:
| Feature | Standard ChatOps | MCP (Model Context Protocol) | A2UI |
|---|---|---|---|
| Payload type | Plain text / markdown | Structured model‑centric data | Declarative JSON UI schema |
| Security model | No built‑in sandbox | Requires custom sandboxing | Agent cannot execute code; only requests whitelisted components |
| Native UI rendering | None (text only) | Depends on client implementation | Client‑side renderer creates native components |
| Bi‑directional interaction | Limited (buttons via callbacks) | Possible but not standardized | Immediate state sync via actions |
| Extensibility | Low (text commands) | Medium (model‑driven) | High – add new component types via schema |
| Use‑case focus | Simple ops commands | General model‑client communication | DevOps / SRE interactive workflows |
The table captures the core differentiators; details may evolve as the specs mature.
Bottom line
A2UI gives Platform Engineers a secure, native, and interactive way to let AI agents do more than spew text. By moving the UI layer into a declarative JSON contract, you get the best of both worlds: the intelligence of LLMs and the usability of native applications.
Give it a try in your next internal tool—your on‑call engineers will thank you.

The bolded entries highlight the most advanced or recommended choice for each category.
Getting Started
Google has open‑sourced the specification and renderers. Clone the repo and run the Restaurant Finder sample to see the rendering in action (it translates perfectly to a Service Finder for DevOps).
git clone https://github.com/google/A2UI.git
Navigate to the client sample
cd A2UI/samples/client/lit/shell
Install and run
npm install && npm run dev
Final Thoughts: The Shift to Generative UI
We are moving away from generic UIs (dashboards that show everything) toward generative UIs—interfaces created on‑the‑fly for the exact problem you are solving.
For DevOps and SREs, A2UI is the toolkit that makes this future possible. It keeps the “Chat” in ChatOps while finally eliminating the “Ops” headaches.
