The Qelos portfolio
Qelos is the company building the application layer and the toolkit around it — one flagship gateway and four focused tools for teams shipping modern, AI-native products.
The application layer for any product.
Application-layer gateway for auth, workspaces, storage, and AI agents. Drop in the plugin, get a branded admin panel and a REST API across every major framework. No rewrite, no lock-in.
Auth & workspaces
Multi-tenant on day one.
Branded admin panel
Ship with your UI, not ours.
Every framework
Express, Nest, Next, Fastify.
AI agents wired in
Auth + data, scoped per tenant.
The rest of the toolkit
Open-source tasks executor for dev work.
AIDev is the open-source executor that runs autonomous development tasks for your team. Use it locally and self-hosted, or let Auto Qelos run it for you as a managed service.
Entitlements and pricing limits, enforced.
Open-source entitlements engine that enforces pricing limits in your application. Define plans, quotas, and usage rules — Prici keeps every feature behind the right paywall.
A JS/TS framework for testing AI skills.
TestAI gives you a real testing framework for AI skills, MCP servers, commands, and subagents — written in JavaScript and TypeScript. Catch regressions in agent behavior before your users do.
An MCP aggregator with guardrails built in.
Better MCP aggregates your MCP servers behind a single endpoint, with automatic token shrinking, PII guardrails, and governance controls. Ship safer agents without rewriting every server.
The hosted Qelos gateway ships auth, workspaces, storage, AI agents, and an admin panel out of the box.
Every new product starts with weeks on auth, users, permissions, storage, and admin UI — before you ship what users asked for.
A branded admin panel. A plugin that drops into your framework — no rewrite, no lock-in. Authentication and authorization. Workspaces to model your clients and their teams. A REST API over a permissioned database. File and asset storage. AI agents and in-app chatbots. Everything you'd otherwise spend a quarter building.
Pick your framework. Drop in the integrator. Every request arrives authenticated, scoped to a workspace, and wired to a typed SDK — without a single line of glue code.
Qelos gives you the whole application layer — wired together, in the framework you already use.
Spin up a Qelos tenant. Install the plugin in your app. Start shipping. Each of your clients lives in their own workspace, with users, roles, content, AI, and storage managed from the admin panel.
Founders skipping the plumbing, agencies shipping the same stack for every client, and teams adding AI without a rewrite.
Every product team hits the same moments — rebuilding invites, wrestling with RBAC, copy-pasting auth for the third client. Qelos handles the plumbing so you can ship the feature instead.
Get a managed Qelos tenant and skip months of backend plumbing, or pick the Qelos tools that fit the gap you're closing today.
Trusted by developers building modern apps.
Teams use Qelos to skip the backend rebuild and ship the part their users actually see — with an open-source core they can read, fork, and trust.
