Sign inGet started

We build the template our agents run on.

DeesseJS is a SaaS starter optimized for the agentic era. Every surface your AI agents need — auth, billing, jobs, storage, notifications — ships wired from day one. The agents are the executors, not just the users.

Why we built this

Most SaaS templates optimize AI for the developer — Claude Code, Cursor, Codex integration. We optimize the system for AI agents. Your agents don't just help you code. They run on DeesseJS, call the tools directly, and build your product while you sleep.

We believe the next decade of software will be built by agents running on production-grade infrastructure. The SaaS templates of 2024 gave you auth and billing wiring. The SaaS templates of 2026 need to give you callable surfaces — every button, every endpoint, every webhook designed so an agent can invoke it without a human in the loop.

DeesseJS is that infrastructure. Not a framework. Not a platform. A complete, wired, type-safe template that ships in minutes and runs anywhere you can deploy Node.

To ship agents

Agents do their best work on infrastructure that fits how they work — typed, wired, and ready to invoke.

For coding agents

Shipping an agent should be as simple as shipping a site. A new repo, a new agent, a new product.

Built by humans

Humans design the system. Agents run on it. The split is intentional and load-bearing.

How we build

Six principles. None are aspirational — every one of them is load-bearing in the codebase.

01
Restraint over decoration
Mono design language. Hairline borders beat shadows. We ship less, more carefully.
02
Modular by default
Every package is removable. No half-built features. The buyer keeps what they use, drops what they don't.
03
Type-safe end-to-end
From database to client, the type is the contract. Hono + oRPC + Drizzle. No codegen step.
04
Agents are first-class users
Every surface has a tool an agent can call. Auth, billing, jobs, storage, notifications, API.
05
Own every line
Self-hosted by default. No vendor lock-in. Your code, your infrastructure, your call.
06
Ship in days, not months
Auth, billing, jobs, storage wired on day one. The boilerplate is done before the first commit.

Who's behind this

DeesseJS is built by Nesalia Inc., a small team focused on agentic infrastructure.

Based across Europe and North America. Async-first. We ship from a single GitHub repo, and every architectural decision is documented in our internal docs. We'd rather show our work than sell you on it.

Not a platform company. Not chasing a billion-dollar exit. Building the best template for solo founders and small teams shipping SaaS in the next 12 months — and getting back to work.
