agents running

one connector in - here's what changes

One memory - one context

Across Claude, ChatGPT and Gemini - agents, files and history follow you and your team. Nothing resets. Agents learn run after run. No lock-in.

>continue this chat in chatgpt

Local → cloud

Prototype in Claude, ship to the cloud - close the lid, it keeps running long after your chat ends. Production, not demo.

>take this chat to the cloud, keep it running

One prompt - a whole fleet

Ten or a million serverless sub-agents - each its own cloud runtime, billed by the second. Scales on our own GPUs.

>run this across all 3,000 rows in parallel

Cloud browsers

Thousands of real browser sessions in the cloud - click, fill, scrape, buy on any site, in parallel. No local Chrome, no captchas.

>send 200 agents to check every page

Runs on a schedule

Every morning, every hour, every Monday. Works nights, reports back before you wake.

>email my users their digest at 8

ALL

Every connector, wired

All connectors already wired - and every AI model. One key.

>post the report to slack and notion

Chat → agent → API

Describe the job in plain words. Freeze what works - the cloud compiles it into a live API. A production agent in minutes.

>freeze this as an api

Human in the loop

On money, sends, deletes - it stops and asks first. Approve in one tap, it goes on. Every run recorded.

>always ask before refunds over $500

Built for teams

Share an agent by link. Roles and permissions - run-only for sales, edit for engineers - one dashboard of every run.

>give the team run-only access

Platform map

Everything your agent needs -
in one cloud.

Connect one MCP, use it forever - for every use-case. FlyMy routes each call to the right model, GPU, storage, memory, skill and connector behind it.

FlyRouter™ - the harness router

Every lane. One router.

OpenRouter routes models. FlyRouter™ routes the whole harness: models, GPUs, storage, memory, skills and connectors - every one a typed MCP tool, picked per call.

Product in action

One sentence in.
One endpoint out.

The same sentence works from every surface you already use. Frozen means frozen: a model update can never drift it - v1 keeps serving until you cut v2.

Hard cost capsAny run stops at the number you set. A runaway agent gets cut off before it gets expensive.

Human-in-the-loop gatesMoney, sends, deletes - the agent stops and asks first. Approve in one tap.

Encrypted key vaultKeys and OAuth tokens never ride in prompts, never hit logs. Your LLM never sees a secret.

One URL for your AI

Show your assistant everything FlyMyAI can do.

FlyMyAI may already be connected to Claude, Codex, Cursor, or Gemini. Start with this guide so your assistant verifies the connection, discovers hundreds of tools and models, and chooses the right personal or resale flow.

Download AGENTS.md View raw guide

Read https://flymy.ai/skill.md and help me integrate FlyMyAI. Start by asking whether this is personal use or resale to my end users.

skill.md and AGENTS.md are byte-identical. Use the copied prompt for one focused session, or save AGENTS.md as a persistent project guide. For resale, one builder key stays on your backend and your end users never paste FlyMyAI keys.

Personal useConnect your own account and services, then continue to Personal MCP setup.

Resale to your end usersKeep one builder key on your backend, scope each user with an opaque external ID, and send connector authorization through short-lived hosted URLs. End users need no FlyMyAI account or key. Open the raw guide for the verified embedded flow.

Continue to MCP client setup

Personal MCP connection

Your coding agent already
knows how to use this.

This setup connects your own FlyMyAI account to an MCP client. It can then assemble workflows, call models, and freeze production endpoints inside your caps and gates. Building for end users uses the embedded resale path instead.
