Freebuild for Kilo Code

Install, connect, and use Freebuild in Kilo.

The Kilo plugin registers the Freebuild provider, connects a license, selects DeepSeek V4.1 Flash 1017, and shows the sponsor panel in the Kilo CLI.

The CLI is the first target. The Kilo plugin works in the CLI today. The VS Code and JetBrains extensions can load the provider, but the native sponsor panel is CLI only for now.

Install

kilo plugin @freebuild/kilo --global

Restart Kilo so the plugin loads.

For a local checkout of this repository:

kilo plugin "C:\Projects\freebuild\freebuild\kilo-plugin" --global

Connect a license

Inside Kilo, run:

/freebuild-license

Choose where to pay

Pick Buy a new license to open checkout, or I already have a key if you bought in the browser.

You should see: the activation page opens in your browser. Keep Kilo open.

Verify your email

Enter the email that should own the license. Click Send code, then enter the 6-digit code and click Verify email.

Freebuild activation page with email address, Send code, verification code, and Verify email — Verify the email before checkout. The same address receives the license link.

You should see: Email verified. Continue to checkout.

Choose a plan and pay

Lite is $5/month for 30M weighted tokens. Standard is $9.50/month for 60M, first month $5. The sponsor panel is included in both.

Stripe test checkout showing the Freebuild plan and total — Stripe test mode screenshot. Use a real card only in production.

You should see: the plan name, the first-month total, and the Freebuild terms line.

Return to Kilo

The plugin polls the activation. When checkout finishes, it saves the key, writes the provider config, and selects the Freebuild model.

You should see: License connected. Choose Freebuild / DeepSeek V4.1 Flash 1017 in /model.

If the model does not appear, restart Kilo once. Kilo may need a fresh config load after the provider is added.

Buy in the browser

Buy on the pricing page, then paste the key in Kilo:

/freebuild-key

You can also pass the key directly:

/freebuild-license fb_...

The plugin verifies the key against the broker, saves it to ~/.config/freebuild/credentials.json, and selects DeepSeek V4.1 Flash 1017.

The Freebuild license works in Kilo, OpenCode, and Pi. The install ID is shared, so a key that is bound to this machine can be used by all three clients.

Use the model

/model

Choose:

Freebuild / DeepSeek V4.1 Flash 1017

Verify the connection:

/freebuild-plan

/freebuild-plan shows the plan label, weighted used and limit, raw tokens, cache hit rate, and reservations. The billing period is on /account.

Sponsor panel

The panel appears at the bottom of the Kilo TUI while a sponsored run is active. On taller terminals it uses a large wordmark and a capped copy block. Smaller terminals use a compact layout.

RAILWAY // PREVIEW SHIP WHAT YOU BUILT Deploy your next project on Railway. New customers get $20 in Railway credits. No server setup. click the ad or alt+o to open

Click the panel body to open the sponsor, or use alt+o:

/freebuild-sponsor

Clicking uses the campaign currently drawn in the panel, so the brand and destination match. The loading and error panels are not clickable.

Preview the campaign before a run:

/freebuild-adtest

The preview stores the campaign on the server. The next sponsored run consumes the same campaign, so the preview and the live panel match.

Non-interactive Kilo runs do not render the panel.

Troubleshooting

Message	What it means	What to do
`install_mismatch`	The license is bound to a different install.	Close every Kilo window, reopen, then run `/freebuild-plan`. If it still fails, paste the current key with `/freebuild-key`.
Freebuild missing from `/model`	The provider is not registered.	Run `/freebuild-setup`, then restart Kilo.
`401` or invalid license	The key was revoked, rotated, or the subscription is inactive.	Get the current key from `/account` and paste it with `/freebuild-key`.
`email_not_verified`	Checkout was started before the email code was verified.	Go back to the activation page, verify the email, then continue to checkout.
`code_used`	The founding code was already claimed.	Use the license email or `/freebuild-key`. Do not start a second checkout.
Panel does not open on click	The terminal does not report mouse events.	Use `alt+o` or `/freebuild-sponsor`.
Broker unreachable	Kilo cannot reach the broker.	Check your network, then retry. The sponsor panel also needs broker access.
