Live workspace
Code, chat, and preview in one place.
The workspace is built for repeated product work, not disposable demos. Every generated file stays inspectable, every change is visible, and every follow-up can target the exact part of the app you care about.
01 · EDITOR
Generated code, ready to edit.
Every file BYOB writes stays visible and editable. Follow-ups target the exact lines you care about instead of regenerating from scratch.

Prompt to app
From first prompt to a workspace you can ship.
Start conversationally, approve the shape, let Tool Mode implement, then refine and deploy from the same workspace.
- 01 Describe the product Start with the outcome, audience, and any constraints. BYOB turns the idea into a practical build plan.
- 02 Shape the UX Review the proposed flows, screens, data needs, and visual direction before code starts moving.
- 03 Generate the app Tool Mode writes SvelteKit code, connects integrations, and keeps each change visible in preview.
- 04 Test and refine Ask for edits, roll back when needed, run checks, and keep the project editable instead of disposable.
- 05 Deploy Ship the finished app, connect domains, and keep iterating from the same workspace.

Loved by builders
Rated 4.9/5 by developers and founders using BYOB to move from idea to shipped product.
Built for shipping
The parts that usually slow you down are already here.
BYOB handles product planning, implementation, preview, testing, database work, and deployment from one focused interface, with coding-agent access and production analytics when you want to keep working from your own terminal.
This part is hands-on. The cards drift until you touch them. Drag to rearrange, or press and hold one to feel it push back.
Agent integrations
Give Codex, Claude Code, or Antigravity scoped access through BYOB CLI or Agent MCP. Your agent reads context, edits code, tests previews, and deploys from your terminal.
Git history and diffs
Every change lands as a commit. Inspect history, compare diffs, and see exactly what changed since the last deploy.
Inbox in every project
Every project ships with an inbox. Collect messages, leads, and feedback from your app without wiring a third party.
Email sending built in
Send magic links, OTP codes, and transactional mail from your own sender address. Resend-backed, no SMTP setup.
Google and magic-link login
Offer Continue with Google plus passwordless email codes. Sessions and callbacks are handled.
Custom domains and SSL
Point your domain at BYOB with guided DNS checks. Certificates are automatic.
Visual editing
Click any element in the live preview and describe the change. Copy, spacing, color, behavior.
AI testing agent
Run full-site or feature checks and get implementation-level feedback you can apply in one step.
Version rollback
Step between saved states or redeploy a known commit when an experiment goes sideways.
One-click deploy
Builds publish to production hosting in one step. Deploys can auto-save the project state first.
Deployment analytics
Worker traffic, errors, CPU timing, subrequests, and custom-domain status from the workspace.
Supabase aware
Connect Supabase and BYOB reads schemas, drafts migrations, and generates types that match your app.
Team collaboration
Invite people in and keep sessions coordinated so work never overwrites work.

BYOB helps Amsterdam construction and renovation firms build a fast, Dutch-first website with an English layer for international clients. Show project photos, explain permits and timelines, and make quote requests simple. Price in euros with VAT at 21% noted, mention iDEAL or card payment, and run it on a.nl domain.
Dutch-first, English-ready for an international city
Amsterdam is unusual in how comfortably business moves between Dutch and English. Local clients expect the primary pages in Dutch, while a significant expat and international owner population reads English without difficulty. Leading in Dutch shows respect for the local market; an English layer means you do not turn away half the city. Publishing both from one BYOB project keeps the two versions in step, so you are not copying edits between separate sites and letting one fall out of date.
Canal houses, narrow stairs and bespoke work
Much Amsterdam building work is bespoke by necessity. Canal houses have awkward floor plans, steep staircases and listed features that rule out standard methods. Photographs and short case notes showing how you handled a difficult Jordaan or De Pijp property are far more persuasive than general claims. Group examples by project type, such as interior renovation, extension or structural work. Clients facing the same constraints will recognise their own situation and trust you more quickly.
Permits, timelines and honest expectations
Amsterdam projects usually involve permits, neighbour consultation and municipal rules, especially in the historic centre. A short page explaining how you handle the permit process, and roughly how long it takes, sets realistic expectations before work starts. Say plainly what you cannot promise, including how heritage or zoning rules can affect a schedule. Contractors who explain the process clearly come across as organised and reliable in a market that values directness and follow-through.
Quotations, iDEAL and euro pricing
Shown in euros, prices should state whether VAT at 21% is included or added, so there are no surprises on the invoice. Many Dutch clients expect to pay by iDEAL transfer or card, and listing the methods you accept removes friction early. A quotation form that asks for property type, rough budget and address area helps you respond with something relevant. Clear, itemised pricing and quick replies suit a market that dislikes ambiguity and values efficiency.
A.nl domain and neighbourhood coverage
A.nl domain reinforces that you are a Dutch business and is instantly familiar to local clients. Pair it with page titles that name Amsterdam and the neighbourhoods you serve, from the Jordaan and De Pijp to Zuid and Noord. Visitors want to know whether you actually work in their area, so a short coverage section helps. BYOB keeps the setup simple and the pages easy to maintain as your portfolio grows.
FAQ
Frequently Asked Questions
Should an Amsterdam construction website be in Dutch or English?
Lead in Dutch for local clients, with an English layer for the city's large international population. Running both from one project keeps the content consistent and saves ongoing effort.
How do I present prices and VAT?
Show figures in euros and state whether VAT at 21% is included or added. Consistent labelling across your website and quotations avoids disputes later.
Can the site explain permit processes?
Yes. A short section on how you handle municipal permits and realistic timelines builds confidence, especially for heritage properties in the central canal belt.
Which payment methods should I list?
iDEAL transfers and cards are widely expected in the Netherlands. Naming the methods you accept early reduces back-and-forth when a client is ready to proceed.
Is a.nl domain worth it?
A.nl domain signals a Dutch business and is familiar to local clients. It is not mandatory, but it supports the local impression and connects easily to a BYOB project.
