AI makes software fast.
We make it right.
A lean, founder-run studio in the EU. Every line an agentic workflow produces is reviewed by a named senior engineer — you own everything we ship, and you can stop after any milestone.
Three ways to work with us
Pick the engagement that fits where you are — a new product built the right way, a rescue for a codebase that stopped scaling, or your own private AI platform. Each has a dedicated page.
Agentic Software Development
Specification-led, review-bound AI workflows under named senior engineers. The methodology behind every Techthos engagement.
View serviceCustom ChatGPT Plugins (MCP Integration)
We build custom ChatGPT plugins as MCP servers — over the API you already run, a legacy system with no API, or a new backend built for one job. Also runs in Claude and Cursor.
View servicePrivate AI Platform
Your company's own ChatGPT-style AI platform, hosted in the EU, connected to your internal systems, with sensitive data redacted before it ever reaches a model.
View serviceVibe-Code Rescue & Rewrite
Senior engineering for AI-built apps. We take over projects built with Lovable, Bolt, Cursor or Supabase and make them secure, stable and ready for real users.
View serviceWhat you can count on
The same four commitments hold on every engagement, whichever service you choose.
Named senior review
No agent output reaches you unchecked. A named senior engineer reviews every change against the specification and is personally accountable for what ships.
Per-milestone, stop anywhere
Buy one phase at a time and stop wherever you have what you need. Each milestone is a standalone deliverable — no obligation to continue.
You own it on payment
Source code, prompts, workflow definitions, and documentation transfer to you as each milestone is paid. No lock-in, ever.
EU data residency & DPAs
Hosted in the EU by default, DPAs signed as standard, full sub-processor disclosure, and a clean handover with runbooks.
Software we built with our own method
Working software as proof, AppLing, our open source modeling language, and Praximos in beta, plus multi-year client partnerships.
AppLing
Declarative modeling for business applications
One validated model of your business application, written in plain .appling files. People and AI agents work on the same model, and it generates draft projects for Django, Ash, Go and Rust.
- Five layers, from domain to experience, checked as one model
- IDE with a graph view and an MCP server for AI agents
- Draft code with a task registry for what is still open
Praximos
Obligations inside your AI assistant
An MCP server, not another dashboard. Praximos plugs into Claude or ChatGPT: state an obligation in plain language, and it handles the deadline, the reminders and the proof of resolution. Free while in beta.
- Runs inside Claude and ChatGPT over MCP
- Reminders run to the deadline on their own
- Recipients answer via one link, no account

Visit WebsiteTools we built, and gave away
We open-source the small, general-purpose tools we build for ourselves. It is how we contribute back — and the most honest proof of how we build.
A single-binary local store for our Go micro-apps: browse a GitHub catalog, install verified release binaries, manage installs, and scaffold new apps — via both a terminal UI and an MCP server.
View app
Prebuilt, interactive HTML widgets for MCP Apps in Go — sortable tables, forms, date pickers and card lists, each a self-contained resource embedded in a single binary. Pre-release, MIT.
github.com/Techthos/gomukitA dual-mode time tracker: an MCP server that lets AI assistants log work in natural language, plus a keyboard-driven terminal UI. It turns git commits into worklogs automatically.
