Auth, database, storage, email, AI, and workflows. All wired together. One SDK. One bill. Describe what you need -- we build it.
import { createClient } from 'morebun'
const app = createClient('my-project')
// Auth — done
const user = await app.auth.signUp({ email, password })
// Database — done
const invoices = await app.db.invoices
.where('status', 'pending')
.limit(20)Everything Built In
Every primitive is wired to every other. Auth knows about database knows about email knows about workflows. No glue code.
Sign up, log in, manage users. Social logins, magic links, API keys. Role-based access control.
Isolated per tenant. Global edge reads. Describe your schema in English -- AI creates tables, types, and indexes.
Upload files. Process them automatically. Resize images, extract PDF text, generate thumbnails.
Send AND receive. Transactional email with templates. Inbound email triggers workflows.
Built for AI apps. Store conversations, track costs per user, route to the right model.
Describe what you want. AI builds the flow. Background jobs, approvals, cron. Gets cheaper as AI compiles to code.
Real-World Use Cases
Whether you're building the next big SaaS, automating enterprise workflows, or shipping AI-powered products -- MoreBun replaces the stack you were dreading to assemble.
Build production-ready SaaS apps with tenant isolation baked into every layer. Each customer gets their own database, their own storage bucket, their own auth pool. Billing, usage metering, and plan limits are native primitives -- not afterthoughts you wire together at 2 AM.
// Create a tenant in one call
const tenant = await app.
.tenants.create({
name: 'Acme Corp',
plan: 'pro',
isolation: 'full'
});
// DB, auth, storage — isolated
const db = app.db.for(tenant.id);
const users = await db
.users.list();“When a purchase order exceeds $10K, route to VP approval. If approved, create the PO in Oracle ERP and notify procurement via email.”
No more dragging boxes in Oracle Integration Cloud. Tell MoreBun what you need in plain English and the AI workflow builder generates the entire flow -- approval gates, ERP connectors, conditional branching, cron schedules, and error handling. As flows mature, AI compiles them to deterministic code for maximum reliability and lower cost.
Stop wrestling with APEX page builders and VBCS visual editors. Describe your data model and MoreBun auto-generates REST APIs with full CRUD, role-based access control, and audit logging. Pair it with any React framework or use our admin UI kit for instant dashboards your ops team will actually use.
// AI with built-in everything
const thread = await app
.ai.thread(user.id);
// Costs auto-tracked per user
const reply = await thread
.chat('Summarize Q4 sales');
// Vector search — native
const docs = await app.ai
.search('revenue trends', {
collection: 'reports',
limit: 5
});Building AI features means stitching together LangChain for orchestration, Pinecone for vector search, custom billing logic for per-user cost tracking, and a database for conversation history. MoreBun gives you all of it as native primitives. Conversation threads, cost attribution per user, intelligent model routing, and vector search -- ready to call from one SDK.
Product catalogs in the database. User accounts in auth. Product images in storage with auto-resized thumbnails. Order confirmations via transactional email. Payment webhooks triggering fulfillment workflows. Every layer of your commerce stack talks to every other -- natively, not through duct tape.
Spin up fully isolated backends for each client project in seconds -- separate databases, separate auth, separate storage. Manage all of them from a single pane of glass. Hand off projects cleanly or white-label the entire platform under your client's domain. No more shared staging servers and crossed wires between client environments.
