Sandbox Size Tiers, Webhooks UI, and Two-Factor Auth

What's new

Sandbox size tiers

Templates now have a size field that controls CPU, memory, and disk. The default is Medium, the same resources previously available to all runs. Larger sizes let agents take on more demanding work: bigger repos, heavier builds, and test suites that need space to run.

Set size when creating or updating a template via the API or dashboard. The run response now includes a sandbox object with the resolved size and resource limits.

Migration: All existing templates default to Medium (m). No action required.

Webhooks UI and delivery health tracking

Webhooks can now be created and deleted directly from the dashboard, no API calls needed.

Each webhook shows a delivery health summary: success rate, total deliveries, last delivery timestamp, and failure reason if the most recent delivery failed. Health is tracked over a rolling 7-day window (or 24 hours via ?window=24h).

The GET /v1/webhooks response now includes a health object per webhook with the full delivery metrics.

Multi-factor authentication

Account security is now stronger with TOTP-based MFA. Enable it from Account Settings. Once set up, a 6-digit authenticator code is required at every sign-in.

• Works with any TOTP app (Google Authenticator, Authy, 1Password, etc.)
• 10 single-use backup codes provided at setup, regenerable at any time
• "Trust this browser for 30 days" option to skip 2FA on trusted devices
• Organization owners can see MFA status for each member

Available for email/password accounts. OAuth sign-ins (Google, GitHub) are protected by the provider's own security.

API changes

• POST /v1/templates, PATCH /v1/templates/:id: new size field ("s" | "m" | "l", default "m")

• GET /v1/runs/:id: response includes sandbox.size and sandbox.resources
• GET /v1/webhooks: each item now includes a health object; optional ?window=24h|7d query param (default 7d)
