What does o8 cost?

o8 is open source and free forever with the model subscriptions and keys you already use. Local repositories and installed or bring-your-own model tools do not require an o8 account. Each installation also gets a limited hosted allowance on demand. Sign-in connects portable account services; Pro pays for managed infrastructure, higher limits, and supported customization.

Free forever, including the source

The full app, the governance gate, the Engineering Brain, and the canvas are free when you run them with your own model subscriptions or keys. The source is MIT licensed, so you can inspect it, fork it, and add anything you want. Your worker runtimes use the access you already have. o8 chat also includes a limited install-scoped hosted allowance without sign-in.

• The orchestrator and the full agent fleet.
• The review gate, merge gate, and conflict detection.
• The Engineering Brain and organizational memory.
• The canvas, the audit trail, and mobile approval.
• Symon, the voice operator.
• A limited hosted-inference allowance, provisioned on demand for each installation.

Why there’s a paid edition

Managed infrastructure costs money to run, so Pro pays for the hands-off path and our most generous daily limits. Every installation still gets a limited hosted model allowance without sign-in. As serving gets cheaper and the model improves, we’ll keep improving that free path too.

Pro — optional, one-time for the first 250

Pro is the paid, managed edition for people who don’t want to maintain a custom fork. The first 250 members pay once, become Founding Operators for life, and keep the cohort price they entered at: $150, then $250, then $500. It is not a subscription or a stake in the company. Pro includes:

• Early access, always on — experimental features land for you a release channel ahead, forever.
• Managed essentials, for life — our most generous daily fair-use limits for the Fast Brain, dictation polish, and premium speech-to-text. You never pay the future infra tier.
• Everything in Free — the whole app and source are already yours forever with your existing model access; this isn’t a paywall.
• Maximum Canvas customization — the supported path for custom photos, WebGL shader scenes, ASCII, and dithered backgrounds as those tools ship, without maintaining a fork.
• Founding Operator status — a numbered badge and your name on the wall.

See live cohort pricing on the Pro page. Stripe checkout and receipts use the Founding Operator name for this first cohort.
