Products

Built by us. Used every day.

Each product started as a real problem we kept running into. We design, build and operate them ourselves, which is also how we know what it takes to ship yours.

Live

Chat Tree

Regenerate shouldn't delete your best answer.

Chat Tree turns every AI conversation into a navigable tree. Edit any question or re-ask any answer and it becomes a new branch, while every earlier branch stays exactly where it was.

  • GPT, Claude, Gemini and Grok in one workspace, no API keys needed
  • Compare four models on the same question, side by side
  • Export to Markdown, JSON or PDF, or share a read-only link

Live

Rapid Cart

Stop losing orders in your DMs.

For bakers, makers, tailors and small service businesses selling through Instagram and WhatsApp. One link in the bio, and customers send a complete order request instead of a scattered thread.

  • Order page live in a minute, no website to build or maintain
  • Tidy dashboard, one-click accept or decline, automatic status emails
  • Print-ready QR codes, spam protection, and API access on the top plan

  • Camera to listing in seconds, straight from the browser
  • One tap to publish across social platforms, no copy-pasting
  • Every listing tracked in one place: draft, active or sold

Consultancy

Senior people, from first sketch to running system.

We take on whole products or the piece your team is missing. Small, direct and hands-on, with the same engineers who build our own products.

Custom web applications

SaaS products, dashboards and internal tools in Next.js and React, with .NET or Node backends and Postgres underneath.

Mobile apps

iOS and Android with React Native and Expo, or native Swift where it matters. Store setup, releases and updates included.

AI integration

Chat, extraction, classification and agent features built on Anthropic, OpenAI and Google models, with evaluation and cost control.

E-commerce and order flows

Checkouts, subscriptions and order management with Stripe, from a single order page to a multi-vendor platform.

Legacy modernisation

Upgrading and re-platforming .NET systems, replacing ageing CMS and workflow engines, and moving to the cloud without a big-bang rewrite.

Integrations and automation

APIs, webhooks, payment and social platform integrations, scheduled workflows and MCP servers that let AI tools drive your systems.

How we work

Fixed price for a well-defined scope. Time and materials when the product is still finding its shape. A dedicated developer when you need someone on the team for the long run. In every case you talk to the engineer doing the work.

Individual development rates are negotiable.

We price per project and per engagement, not from a rate card. Tell us what you are building and we will come back with an honest estimate.

About

Then, now, next.

BAP Software Ltd is a small Irish software company. The name comes from our first product, and the focus has moved on since.

Then

The BAP platform

We started with BAP, our own .NET business automation platform: workflows, CMS, e-commerce and multi-tenant systems, delivered for clients in telecom, transport, healthcare, real estate and finance. That work is where our engineering habits come from.

Now

Consultancy and our own products

Today we split our time between client projects and products we run ourselves. Chat Tree and Rapid Cart are live and growing, and everything we learn operating them feeds straight back into consultancy work.

Product thinkingWe ship and support our own software, so we build yours to be operated, not just delivered.
Direct accessNo account managers in between. You work with the engineers.
Modern stackTypeScript, Next.js, React Native, .NET, Postgres and current LLM APIs.
Flexible engagementFixed price, time and materials, or a dedicated developer. Rates negotiated per project.
