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.

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.

A real estate website builder for São Paulo should be Portuguese-first, fast on mobile, and built around WhatsApp and Pix. BYOB lets you publish a.com.br property site with listing galleries, prices in reais, and direct contact, so paulistanos can shortlist homes by bairro and reach you in seconds.
Why bairro detail converts in São Paulo
São Paulo is a patchwork of neighbourhoods, and buyers think in terms of bairro as much as city. Living in Pinheiros, Vila Mariana, or Itaim Bibi implies a different routine, commute, and lifestyle. A listing that describes the street, the nearest metro station, the local padaria, and the feel of the area is far more useful than one that repeats generic adjectives. Portuguese copy written for paulistanos, not translated from English, signals that you understand the city. When a buyer can picture daily life in a neighbourhood, they engage seriously with the property rather than scrolling past.
Mobile-first for a phone-driven market
In Brazil, and especially in São Paulo, most people access the internet through a smartphone, and property searches are no exception. Pages must be light, fast, and readable on a small screen, because data plans and network speeds vary across the city. Put the price, the condominium fee, and the number of rooms near the top so a buyer can assess a listing at a glance. Compress images aggressively and avoid scripts that block rendering. A site that respects limited bandwidth will keep visitors engaged, while a heavy page that stalls will send them straight back to the portal they came from.
WhatsApp and instant contact
São Paulo runs on WhatsApp, and property conversations often begin there rather than by email. Make a chat button prominent on every listing so an interested buyer can ask a question immediately. Because people expect quick answers, set an automatic greeting and a realistic response window. For rentals, a short form can capture move-in dates and guarantor details upfront. Offering a viewing scheduler saves time for both sides. When contact feels as easy and immediate as messaging a friend, you convert far more of the visitors who are genuinely interested rather than merely browsing.
Pix, prices in reais, and Brazilian taxes
Prices are quoted in Brazilian reais, and taxes vary between federal, state, and municipal levels, so total costs deserve a clear explanation. Pix has become the default for instant payments and is used even for deposits and reservation fees, alongside cards. Show what a condominium fee covers and whether IPTU and other charges are included in the quoted figure. For sales, be transparent about ITBI and notary costs, which buyers will face at closing. Making these numbers visible in Portuguese, with no vague language, builds the confidence that a Brazilian buyer needs before moving forward.
Standing out in a vast, competitive market
São Paulo has an enormous number of agencies and listings, so a generic site simply disappears. Positioning around a specific segment, such as apartments in a particular bairro, high-end launches, or commercial space, makes you memorable and easier to recommend. Add local expertise that portals cannot replicate, including what a building's management is like or how traffic affects a commute at peak hours. Genuine client reviews matter, because referrals are central to how business travels here. A focused, well-organised site gives buyers a reason to contact you directly instead of joining a queue of competing enquiries.

FAQ
Frequently Asked Questions
Does my São Paulo property website need to be in Portuguese?
Yes. Local buyers and renters search and compare in Portuguese, so a Portuguese-first site is essential. An English version can help foreign investors, but it should support rather than replace the Portuguese content.
Can buyers and renters pay through Pix on the site?
Pix is widely used for deposits, reservation fees, and other instant payments, and you can accept it alongside cards. Show amounts in reais and explain clearly what each payment covers.
How do clients usually get in touch about a listing?
WhatsApp is the most common channel in São Paulo, so a prominent chat button is important. A short form and a phone number cover people who prefer to enquire in different ways.
Should I show condominium fees in listings?
Yes. The condominium fee is a routine part of the monthly cost in Brazil, so displaying it alongside the price and clarifying what it covers helps buyers compare properties honestly.
