Leave Localhost 1.0

Leave Localhost is out. This is the full, production-ready foundation: the integration weeks are already done, and everything below ships in the first commit.

Core platform

• Convex-first backend with typed functions, reactive queries, file storage, and scheduled work as the single data platform — no separate database, ORM, and real-time layer to keep in sync.
• Better Auth integrated with the Convex backend and the organization model, including two-factor authentication and fresh-session checks.
• Workspaces and invitations with members, roles, and RBAC.
• Capability-based authorization so product actions are gated by named grants instead of scattered conditionals.

Billing that grants access

• Billing adapters for Stripe, Polar, and Lemon Squeezy behind a provider-neutral interface — configure one.
• Verified webhooks map to entitlement grants, so a confirmed payment becomes a capability the app can check, not just a stored receipt. Plan changes flow through the customer portal and update entitlements.

Security in the flows

• Fresh-session and sensitive-action verification that re-checks identity before consequential actions instead of trusting an old login.
• Audit events recorded for consequential changes.
• Notifications for relevant account and workspace activity.
• Super-admin controls gated by their own capability grants, separate from normal app roles.

Operations and developer experience

• Transactional email via React Email templates.
• Optional analytics boundary that loads PostHog only when enabled, with a no-op fallback and a typed event catalog with property sanitization.
• Agent-ready monorepo — AGENTS.md, CLAUDE.md, Cursor rules, Convex guidelines, a version-locked skill library, strict types, and linter-enforced package boundaries so coding agents build to the project's conventions.
• Shared UI package on shadcn and Radix with semantic theme tokens, plus a documentation app and a typed configuration package.
