Build / Custom Tooling

Custom Tooling.

When the tool you need does not exist, we build it.

By Brian Gagne & Meelie Gagne · March 14, 2026 · Updated March 19, 2026

The workaround tax

Every business has that one workflow held together by spreadsheets, copy-paste, and someone who memorized the steps. It works until that person is out sick. Or until someone pastes into the wrong column. Or until the volume doubles and the manual process cannot keep up. SaaS products are built for the average customer. When your workflow does not match their assumptions, you end up with workarounds. Each workaround is a point of friction, a source of errors, and time that could be spent on actual work.

When custom makes sense

Custom tooling is worth building when the cost of working around existing tools exceeds the cost of building what you actually need. The signals are clear: your team spends hours on manual processes that follow predictable patterns. You are paying for three SaaS subscriptions that each handle a third of the same workflow. Or you need capabilities that simply do not exist in anything you can buy. Custom does not mean complex. Some of the most effective tools we have built are simple CLI scripts that automate a specific sequence of steps. The tool does the boring part. Your team does the thinking.

40+
custom tools built in-house

We have built 40+ custom internal tools for our own operations -- security platforms, business intelligence systems, voice synthesis clients, e-commerce templates, content automation pipelines, design systems, encrypted communications, and infrastructure management. Each one exists because nothing off the shelf fit how we actually work.

We use what we build

Every tool we build for clients follows patterns we have proven in our own operations. We run our business on custom tooling every day. We know what holds up under real use and what looks good in a demo but breaks in production.

What we actually build

CLI tools for automation and scripting. Desktop applications built on modern frameworks with Rust backends for performance. MCP servers that give AI agents structured access to your systems. API integrations that connect tools that were never designed to talk to each other. Web interfaces for specific operational needs. We build in Rust for performance-critical work, Python for automation and data pipelines, and Go for networking applications. We publish open source tools too -- a Rust-based secrets manager with AES-256-GCM encryption, a system information display on crates.io, and a Chrome extension that detects AI-generated slop using 180+ detection patterns. You can check our public work before you hire us.

Replacing a 10-person team with custom tooling

Problem

Running a full-service technology studio across security, content, infrastructure, and client delivery requires capabilities that typically need 10-14 specialized staff members.

Solution

Over several years, we built purpose-specific tools for each operational domain using our LTFI methodology. Content pipeline tools automate daily publishing across 6 platforms. Security tools orchestrate 500+ assessment capabilities. Infrastructure tools manage fleet-wide secrets, DNS, backups, and provisioning. Each tool does one job reliably.

Outcome

Two people delivering the output equivalent of a 10-14 person team. The equivalent salary cost for that headcount would be $1.15M-1.7M/year.

Custom tooling is not about replacing people. It is about making the people you have dramatically more effective by automating the work that should not require human judgment.

How it connects to everything else

Custom tools rarely live in isolation. They connect to your ERP systems through API integration. They plug into AI agent workflows through MCP tool orchestration. They get maintained and monitored through managed services. The first conversation is free. We will look at where your team is spending time on work a tool should be doing. No commitment, no pitch -- just a straight assessment. Reach us at kief.studio/contact.

Frequently asked questions

How long does it take to build a custom tool?

A focused CLI tool that automates a specific workflow can be built and deployed in a week. A full desktop application or web platform with complex business logic takes longer. We scope during discovery so you know the timeline and cost before committing. Many of our own 40+ tools were built in days, not months.

What happens if we need changes later?

Custom tools are yours. The code is documented, the architecture is straightforward, and we provide ongoing support through our managed services. Changes are typically faster and cheaper than the initial build because the foundation is already in place and designed to be modified.

Can we see examples of your work before committing?

Yes. We publish open source tools on crates.io and the Chrome Web Store. Our Trustpilot reviews at trustpilot.com/review/kief.studio are public. And we are happy to walk through relevant examples during a discovery conversation -- the first one is always free.
