Solutions

Built around how you actually work.

Whether you are a studio of three or a company of three hundred, Devquiry stays on your side of the firewall.

Agencies & studios

Keep every client’s files, invoices and campaigns in one private stack. White-label the portal. Never pay per seat again.

SaaS & product teams

Run lifecycle email from your own VPC. Sync InvoiceFlow with your billing events. Own the audit trail.

Regulated businesses

Data residency by design. Nothing phones home. Deploy in your region, on your terms, with your compliance officer’s blessing.

Founders who are done renting

Buy the tool once. Host it on a ₹800 VPS or your own rack. Sleep knowing a pricing page cannot evict you next quarter.

Documentation

Install it. It’s yours.

Installation

Devquiry products ship as a single Docker Compose stack or a bare-metal tarball. You need a Linux server, 2 GB RAM and a domain.

Quick start

curl -fsSL https://get.devquiry.com/install.sh | bash
cd /opt/devquiry
cp .env.example .env
./devquiry up

Point your reverse proxy at port 8080. The first visit walks you through the owner account and license activation. Nothing is sent to us unless you opt in to update checks.

About Us

Software with a spine.

Devquiry is an independent studio building self-hosted tools for people who are tired of renting their own work. We believe ownership is not a feature — it is the product.

The name is a small joke we kept: dev + enquiry. Ask better questions of your stack. Host the answers yourself.

We paint our house in the language of Pichwai and miniature — a reminder that craft, patience and patronage still matter, even when the medium is a server.

Devquiry craft

Independent

No venture leash. No growth-at-all-costs dashboard watching you.

Private by default

We cannot see your data because we never receive it.

Made to last

Licenses do not expire. The software keeps running if we ever go quiet.

Get Started

Take the keys.

Tell us what you want to host. We will send a license, the installer and a short setup call if you want one.
