The platform

One studio, every surface.

Author, share, and embed agents from a single screen. No second admin app. No labyrinth of settings.

Truly model-agnostic

Anthropic, OpenAI, Gemini, OpenRouter, local Ollama. Switching providers is a dropdown, not a migration. Bring your own keys.

Hybrid retrieval, with sources

Vector + lexical retrieval over pgvector. Inline citations open the exact source chunk.

MCP, both ways

Attach any Model Context Protocol server in seconds. Publish your agent as one — every FyrAgent is also a tool other agents can call.

Smart conversation starters

Starter chips are LLM-generated from what's actually in your knowledge base — and re-cluster as the KB grows. Nobody else does this.

Embed in one line

Self-contained web component with Shadow DOM. Bubble + inline modes, themed automatically.

Visible memory

Three-layer memory — global preferences, per-agent overrides, auto-extracted facts. All editable. All on-screen.

Versioned publishes

Drafts edit freely; only publishes affect live conversations. Rollback in one click. Diff any two versions.

Inspectable tool calls

Every tool invocation shows arguments, latency, and result inline in the chat. Debugging finally feels normal.

Scoped keys, share tokens

Org keys, agent-scoped publishable keys, revokable share tokens. Domain allowlists per embed.

The flow

From zero to live in three steps.

01

Describe the agent

Name it, give it a system prompt, paste a few knowledge sources. We'll auto-generate an avatar, color, and four conversation starters from your description.

02

Test it next to the config

The live preview replays every change. Switch model providers, adjust the prompt, watch citations and tool calls inline.

03

Publish and embed

One click to publish a versioned snapshot. Copy a single script tag onto your site, or share the link. Your edits never break running conversations.

The embed

One line. Any site. Themed automatically.

Self-contained web component with Shadow DOM isolation. Use the bubble mode for support, the inline mode for landing pages. Pass setUser() to personalize for logged-in visitors.

Trust, by default

Visible memory.
Editable preferences.
Versioned publishes.

  • Every "remembered fact" the agent infers is visible in the user's panel — and one tap away from deletion.
  • Inline citations point at the source chunk, with a snippet on hover.
  • Every publish is a versioned snapshot. Rollback in one click, no re-creating.
  • Tool calls are inspectable. The agent earns trust by being legible.

Common questions

We've heard most of them.

Custom GPTs are locked to OpenAI's models, OpenAI's UI, and OpenAI's pricing. FyrAgents is model‑agnostic (Anthropic, OpenAI, Gemini, Ollama, OpenRouter), works as a script you embed on your site, and gives you real per‑agent analytics, MCP integration, and versioned publishes.

Stop renting your agents from a store.
