AI Skills
An AI builder is only as capable as the context it can bring to a task. BYOB uses skills - modular, reusable playbooks - to give its agent expert knowledge for specific domains, from routes to and built-in payments billing.

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.

02 · AI COMMAND
Plan, build, and refine in one chat.
Describe the outcome once. BYOB turns it into a build plan, implements it step by step, and keeps every change visible while you iterate.

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.
Agent and backend
Code with your agent, ship with a real backend.
Connect Codex, Claude Code, or Antigravity to your project, then store data and ship to production without leaving the workspace.

- Installs the byob command

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.

- Voice coding
- Project templates
- SEO-ready output

AI skills are reusable instruction packs that extend what an AI agent can do in a specific domain. BYOB ships skills for, UI kits, built-in data storage, a data source, storage, payments, analytics, login, SEO, PWA, copy, icons and motion, and the agent loads only the ones a task needs.
What an AI skill actually is
A skill is a structured reference pack, not a plugin that installs new software. It bundles instructions, conventions, code patterns and known pitfalls for one domain, fronted by metadata that tells the agent when the skill applies. When a task touches that domain, the agent loads the skill and follows its guidance instead of improvising from memory. The result is code that matches how the platform and framework expect to be used, whether that means valid migration syntax, correct Better Auth wiring, or accessible form markup.
Why domain playbooks beat one giant prompt
Stuffing every possible rule into a single system prompt wastes context and dilutes the guidance that matters. A focused skill keeps the model's attention on the framework, library or pattern in front of it. BYOB's workflow treats skills as gates: before writing UI it loads the and references, before touching payments it loads the provider playbooks, and before adding analytics it loads the instrumentation guide. That ordering is what keeps a long build consistent from the first route to the last, rather than drifting as the conversation grows.
The domains BYOB keeps expertise for
The library covers the work a generated app actually involves: login and server patterns, UI-kit adapters, design techniques and icon sets, with environment handling, managed data and row-level security, object storage and signed URLs, built-in payments, first-party analytics, login, SEO metadata, PWA setup, and user-facing copy. Because each skill is maintained independently, correcting a pricing pattern or a login flow updates every project that reaches for it, without rewriting the builder itself.
How skills reach your coding agent
BYOB's knowledge is not trapped in the hosted chat. When you install the for Codex, Claude Code or Antigravity, it downloads the coding skills into the local skill folders those agents scan, rewriting the names with a byob_ prefix. A shared byob_cli skill supplies the platform contract, while the implementation skills carry the framework detail. Refreshing is a single command, so an agent on your laptop follows the same conventions as the hosted builder and does not silently drift to outdated guidance.
Loading only the relevant skills
More knowledge is not automatically better. Loading every skill for a small styling change would crowd out the files the agent needs to read. BYOB maps task types to mandatory clusters and can suggest a set for a given domain, so data storage change pulls the and environment skills while a landing-page pass pulls the design, copy and SEO references. The agent still reads your actual code first; skills supply the conventions that code should satisfy, rather than replacing the need to inspect the project.
What skills cannot do
Skills are guidance, not capabilities. A skill cannot make BYOB perform an operation the platform does not support, and it does not guarantee that generated code is correct. They reduce avoidable mistakes - wrong connections shapes, missing states, insecure defaults - but the output still runs through validation and should still be reviewed. Treat them as a well-briefed expert on call, not an autopilot. When a skill is unavailable, the honest behavior is to say so and proceed carefully rather than pretend the knowledge was applied.
FAQ
Frequently Asked Questions
What are AI skills in BYOB?
Reusable instruction packs that give the BYOB agent domain-specific expertise, such as server patterns, migrations or built-in payments checkout flows, which the agent loads when a task touches that area.
Do I have to install or manage skills myself?
No. The hosted builder manages them automatically, and the syncs them into local coding agents so they can be refreshed with one command.
Do skills make BYOB support technologies it otherwise would not?
No. Skills improve how the agent applies technologies BYOB already supports; they do not add platform capabilities that do not exist.
Can agents like Codex or Claude Code use BYOB skills?
Yes. Installation writes the shared byob_cli contract and the implementation skills into the skill folders those agents discover.
Are AI skills the same as Model Context Protocol?
No. Skills supply knowledge and conventions, while is the connection that exposes tools and project operations to an agent.
