The fullstack framework for building agents in Rails

The fullstack framework for building agents in Rails

The fullstack framework for building agents in Rails. Build, test, deploy, and monitor in one platform.

A Rails-native DSL, coding-agent docs, Playbooks, Connectors, Slack channels via Open-Wire, Packages from open registries, and the cloud to test, deploy, and monitor.

Our mission

Make AI agent development a zero-knowledge task for Rails developers.

You shouldn't have to become an AI engineer to add agentic features to your app. Rails Agent turns the Rails skills you already have into production-ready agents — one install, docs + Playbooks, one deploy.

Zero AI knowledge

You don't need to understand LLMs, embeddings, or prompt engineering. If you can write Rails, you can ship agents.

Docs-first build

Follow embedded Dashboard Docs and your external coding agent. Local app/agents/ files are the source of truth — scaffold blank or from a Playbook.

BYOK model keys

Attach encrypted provider credentials per workspace and agent. Model spend bills your OpenAI, Anthropic, or other account directly.

Build to deploy to monitor

One platform covers the whole lifecycle: draft, test, ship, and watch — no separate tools to wire up.

Scalable agentic infra

Hosted runtime, autoscaling, retries, and tracing are included. We handle the hard parts so you don't have to.

Unified monitoring & debugging

Every trace, log, error, and cost is searchable in /agents. One place to understand every run.

Four agent types

Knowledge and Workflow

Every agent maps to a typed Ruby base class. Pick a type at create time or when cloning a Playbook — the scaffold includes metadata and the right gem base.

Knowledge Agent

Eg: Answer “Where is order ORD-1001?” from your Rails database and support docs.

RailsAgents::KnowledgeAgent

Workflow Agent

Eg: New order → update order info in Google Sheets and send an email notification.

RailsAgents::WorkflowAgent

Zero config

You write the agent.

No vector database or Redis to provision. Attach provider keys under Settings → Providers. Rails Agent Cloud runs the production harness — model spend bills your provider; managed infra is pass-through at cost plus a transparent 5% service fee when metered.

Your job is agent logic in app/agents/. We handle deploy, scale, traces, and monitoring.

• Models
BYOK — attach OpenAI, Anthropic, Google, or OpenRouter keys. Optional :auto fallback when configured.
• Vector store
Embed and retrieve knowledge. No pgvector, no Pinecone.
• Queue & workers
Long-running tools, streaming, retries — all handled.
• Deploys & scaling
Push once, we autoscale. Rollbacks in one click.
• Traces & logs
Every run, every tool call, every token — searchable.
• Platform keys
rak\_\* API keys for cloud auth — distinct from provider BYOK.

The whole idea

Your agent is a directory.

No YAML soup. No hidden config. Every agent is one folder inside your existing Rails app — and you can read it top to bottom in a minute.

• ▸app/agents/support/
• •agent.rb
• ▸tools/
• ▸connectors/
• •memory.rb

generated by rails agent new support

01

Your agent is a folder

`app/agents/support/`

One directory per agent. Everything it needs lives inside it — nothing hidden in config, nothing scattered across the repo.

02

The brain

`agent.rb`

A plain Ruby class. Pick a model, write the instructions in English. That's the whole agent.

03

Things the agent can do

`tools/`

Each file is one action — look up an order, send an email, refund a charge. Just Ruby methods on your existing models.

04

One-click connectors

`connectors/`

Connect Google Sheets, Notion, HubSpot, and 3,000+ apps — OAuth managed for you. Install from the dashboard Integrate tab.

05

What it remembers

`memory.rb`

Per-user, per-thread or per-org. We store it, back it up and expire it. You just say what to remember.

06

What it knows

`knowledge/`

Drop in PDFs, markdown, or point at a database. We chunk, embed and retrieve — no vector DB to run.

07

How you know it works

`evals/`

Example conversations with the answers you expect. Every change runs through them before shipping.

08

How it talks

`prompt.md`

The system prompt in plain markdown. Edit it in the dashboard, commit it in git — same file, same source of truth.

Connectors

1,000+ apps, one-click install.

Connect Google Sheets, Notion, HubSpot, Slack, and thousands more — OAuth handled, tools ready for your agent. No custom integrations to build.

Packages

Skills and tools from open registries.

From Build → Packages, search Skills.sh, Smithery, and Microsoft APM — then attach packages into the agent folder your Rails app already syncs.

Skills.sh

Agent skills

Browse and attach skills from the Skills.sh registry into your agent.

Smithery

MCP servers

Discover Smithery packages and wire tools into Build → Packages.

Microsoft APM

Agent Package Manager

Install Microsoft APM packages alongside your Rails agent files.

Playbooks

250+ playbooks. Pick one, ship an agent.

Start from a real Rails use case — support, sales, finance, ops, and more. Clone a playbook to scaffold agent.rb, prompt.md, and metadata, then customize in Overview.

Channels

One agent. Every channel your users already use.

Slack, Teams, WhatsApp, web chat, email, Discord, Telegram, SMS, GitHub, Linear, cron, and HTTP — the same agent brain, delivered through OpenWire so you are not rebuilding OAuth and event plumbing for each surface.

How it works

Easy enough that Playbooks do the heavy lifting.

Add the gem, open `/agents`, follow docs or clone a Playbook. Four steps — no AI course required.



"Docs first, ship fast." — Rails Agent

1. 01

Add the gem

In your Gemfile: gem "rails-agent-stack", github: "Tiny-Bubble-Company/rails-agents" 2. 02

Install

bundle install, then bin/rails generate rails\_agents:install. Mounts the engine and prepares credentials. 3. 03

Start your Rails server

bin/dev, then open /agents — like Sidekiq. Sign up, add a provider key, follow Dashboard Docs. 4. 04

Scaffold & customize

Blank agent or Playbook clone scaffolds agent.rb, prompt.md, and metadata. Edit locally or with your coding agent.

Everything you need for production agents

Durability, sandboxing, human-in-the-loop, and evals are built into the framework. Focus on building your agent.

Durable Execution

Workflows survive crashes and restarts. Every step is checkpointed. Agents park when waiting, resume on the next message.

Library & Playbooks

Reuse shared knowledge and skills across agents. Clone Playbooks into app/agents/ and customize in code or the dashboard.

Budget & Guardrails

Monthly token budgets with admin alerts, plus policies for model access, prompt-injection detection, and sensitive-info redaction.

Slack, Teams & Email

Connect Slack and Teams via Open-Wire. Connect company mailboxes (Gmail/Outlook) on the Email channel for inbound and outbound.

Packages & registries

Search Skills.sh, Smithery, and Microsoft APM from Build → Packages and attach skills into the agent folder.

Memory by default

New agents remember across conversations out of the box. Turn memory off per agent when you want each chat to start fresh.

Human-in-the-Loop

Tools that need confirmation trigger approval gates. Sessions park until resolved, then resume seamlessly.

Evaluations & Monitor

Define eval suites with scoring rubrics. Watch runs, tokens, and cost from Monitor — then tighten budgets when needed.

How we compare

Other Rails AI gems give you a client. We give you the whole platform.

RubyLLM and ActiveAgent are great libraries. But you still need AI knowledge, build the dashboard, and run the runtime yourself. Rails Agent ships the whole platform — no AI expertise required.
