The book, the floors, and every swap settle on Solana devnet. A mainnet wallet is looking at a different cluster.
Name the two coins
Pay one stable and receive another. Both sides read the shared reserve, so size is not stuck in a single pair.
Claim, or buy with SOL
Claim 1,000 nUSDC once per wallet. Or pay SOL and mint 100 whole tokens of any book coin. The book itself does not move.

Watch it for real.
A Team of three in Agentfly: Build writes the code and tells Docs it is ready, Docs writes the README, and Review picks up Build's handoff. Every window, message and badge is the app itself.
A real Agentfly window, recorded from the app. The model's replies were scripted for the recording.
Talk it into existence. Or write every line.
Two windows on one project. Switch whenever the work changes.
Describe it. Agents build it.
Agentfly opens in Vibe: a conversation, not a wall of code. Say what you want and watch it get built.
Agents plan the work, write the code and run your tests.
Run several at once - each works in its own copy of the project.

THE BOOK
One reserve. Eight floors.
Depth is not split across six pair markets. The seed leans toward a dollar, and a broken floor steps aside.
✧01 / BOOK
Four coins. One surface.
Paying nUSDC to receive nUSDe reads the same balances as paying nPYUSD to receive nUSDT. The fee is one basis point, kept by the pool.
We believe every developer deserves the tools to bring an idea to life—and a share in the value their attention creates.
Agentfly brings an AI workspace, a code editor, terminals, and Git together in one free app. An occasional sponsored card funds the editor, and 50% of eligible ad revenue is credited to the developer.
Our goal is simple: help more people be creative, build something of their own, and earn while they do it. We’re building Agentfly in the open, with developers at the centre of every decision.

Questions
The things people ask first.
What is Agentfly?
Agentfly is a free, ad-supported code editor. It provides Monaco-based editing, integrated terminals, git, workspace search, and AI assistance. Instead of charging a subscription, it shows an occasional sponsored card in the corner of the editor and credits a share of the advertising revenue to the developer using it.
How much does Agentfly cost?
Agentfly is free. There is no subscription, no trial, and no paid tier. The editor is funded by advertisers, and a share of what they pay goes to the developer rather than only to the vendor.
Is the AI in Agentfly free?
Yes. Agentfly includes free AI models from its partners, Tagflow AI and Heabsy. Sign in with a verified account and start building - no API key and no bill, within a daily allowance that resets at midnight UTC. You can also use your own provider key or a model running on your computer.
How much can you earn using Agentfly?
Advertisers bid in a second-price auction from $1.00 per 500 impressions. The developer receives 50% of the winning ad's clearing price, so earnings vary with live demand. Agentfly is a way to use a capable editor for free with some money coming back, not a promise of income.
Does Agentfly read my source code?
No. Ads are targeted using a fixed list of 45 generic tags such as the programming language and framework in use - for example 'lang:rust' or 'fw:react'. File contents, file paths, and project names never leave the machine. AI features send only what you explicitly ask them to send.
Is Agentfly open source?
Yes. The editor, this website and the ad server are open source under the Apache License 2.0, in one public repository at github.com/bluethenics/adcode. You can read the code, build it yourself, change it and share your version. The Agentfly name and logo are not covered by the licence, so a changed copy needs its own name. Earnings and payouts are handled by Agentfly's own server, which pays only for views whose receipt it can verify.
When does Agentfly show ads?
Sponsored cards appear in the corner of the window and never interrupt typing, debugging, or a running terminal command. They are rate limited, they can be reduced or switched off entirely in settings, and the server enforces a cap that the client cannot loosen.
How are Agentfly earnings tracked?
Every credit is a row on an append-only ledger visible in the editor and on the web dashboard. Entries are never edited or deleted; a correction is recorded as a separate reversal that references the original, so the full history stays auditable.
What platforms does Agentfly run on?
Agentfly runs on Windows and Linux; a macOS build is waiting on Apple notarisation. On Windows it installs from the Microsoft Store in one click; on Linux there is a .deb and an AppImage, or a single terminal command on either. It updates itself when a new version is released.
