Vibe coding
Best models for vibe coding. Then what?
Claude, ChatGPT, Cursor, and Grok can all build you a working app from a description. Rankings shift every month—but whichever model you pick, the hard part is what comes next: hosting the app privately and sharing it with your team behind one login. That's Croft.

Quick answer
Rankings move fast. As of early October 2026, Claude Sonnet 5.5, Claude Fable 5, and GPT-6 Astra lead public benchmarks at building complete apps from descriptions. Vibe Code Bench is one useful snapshot—it measures end-to-end web app building, not just unit patches—but scores shift monthly as new models ship.
After you build the app, you still need somewhere private to share it with the team: a server, company login, a database, backups. That is hosting, and it is where most vibe-coded prototypes die. Croft is model-agnostic hosting—connect whichever assistant you use, deploy the app, and your team opens it behind one login.
What vibe coding means
Describe an app in plain language. The AI writes the code.
Vibe coding is building software by describing what you want to an AI assistant and steering until it is right—no code editor, no computer-science degree.
You bring the idea. The AI writes the code.
Describe the tool in plain language. The AI generates the working app. You bring the taste to know when it works; the AI writes the code. No blank editor, no computer-science degree required.
Steering is the skill
Knowing how to describe what you need, how to react when the first attempt is not quite right, and how to steer iteratively until the app does what you meant. You need clarity, patience, and the nerve to say "not quite, try again."
A chat window is not a home
Build something useful and you immediately need to solve: how do I keep it running? Give it a database? Put it behind a login so only my people can use it? That is the part the AI cannot do on its own—and it is why Croft exists.
How to choose
Pick the model that fits your workflow.
There is no single "best" model—it depends on the job, your budget, and which assistant you already work with. Here is how to think about it.
Strong all-rounder for full apps
For realistic end-to-end web apps with authentication, database, and UI, the frontier models—Claude Sonnet 5.5, Claude Fable 5, GPT-6 Astra, Claude Opus 5—now clear 88-92% on Vibe Code Bench. They handle complex multi-step builds and debug their own mistakes.
Faster or cheaper for drafts
For small internal tools, quick prototypes, or tight budgets, mid-tier models like Claude Sonnet 5, GPT-5.6 Sol, Grok 4.6, or Muse Spark 1.2 (79-81% on the bench) are faster and cheaper while still competent at common patterns.
Open-weight options
If you prefer self-hosting or full model control, Kimi K3 (84.96%, the first open-weight model in the top tier), DeepSeek V4 Pro (82.3%), and others are closing the gap. Pair them with an MCP client and deploy to Croft the same way.
Pair with the assistant you already use
The best model is often the one in the assistant you already know: Claude for artifacts, Cursor for IDE integration, ChatGPT for conversational flow, Grok Build for speed. All connect to Croft the same way.
Vibe Code Bench snapshot
One public benchmark for realistic app building.
Vibe Code Bench from Vals.ai measures how well models build complete web applications from natural language—authentication, database CRUD, UI testing, the full stack—not just isolated functions or unit patches. Scores change as new models release.
As of early October 2026 (v1.1 published snapshot):
- Claude Sonnet 5.5 leads at 92.39%, completing realistic app-building tasks more reliably than any other model tested, at lower cost and faster than Claude Opus 5.5.
- Claude Fable 5 (90.35%), Claude Opus 5.5 (90.29%), Claude Fable 5.1 (90.26%), and GPT-6 Astra (89.59%) form the next tier—all above 89%.
- Claude Opus 5 (88.40%), Grok 4.7 (86.18%), Muse Spark 1.3 Max (85.86%), and Kimi K3 (84.96%, first open-weight model to reach the top tier) follow closely.
- The frontier has more than doubled since February 2026, when the top score was 41.31%. Distribution across apps is uneven, but the movement is large.
These numbers are a snapshot, not gospel. Your mileage depends on the complexity of your app, the clarity of your description, and how well you steer. Rankings will shift again next month.
When a major model drops, we cover it on the blog.
Models vs assistants
Buyers confuse the model with the product.
"Claude" and "ChatGPT" are the places you work—the chat interface, the IDE integration, the artifact preview. The underlying model (which version of Claude, which GPT variant) is often selectable. The assistant is your workflow; the model is the engine.
Claude
Anthropic's chat assistant and artifact builder. Claude lets you pick Sonnet, Opus, or Haiku models (and extended-thinking versions) depending on your plan. Strong at iterative steering and live artifact previews. Free plan uses Sonnet.
ChatGPT
OpenAI's conversational assistant with Canvas for multi-turn code editing. Plus and Team plans let you switch between GPT-5, GPT-6 variants (Sol, Luna, Terra, Astra), and specialized models. Great for non-coders who think in conversation.
Cursor
AI-native code editor with Composer agents. You pick the model (Claude Sonnet, GPT-6, Gemini, etc.) per task. Built for developers who want full IDE integration, not a chat window—best when you know what good code looks like.
Grok Build
xAI's conversational builder with live preview. Uses Grok 4.x models (speed-optimized). Fast iteration cycles for prototypes. Works on the free plan.
All of these assistants connect to Croft the same way—via MCP, a one-time setup. After that, describing an app in any of them ends with a working link on your private server.
After you build
Whichever model you pick, you still need somewhere to host it.
The AI can write the app. What it cannot do is give that app somewhere dependable to live—a private server, company login, a database, backups, rollbacks. That is Croft.
Share with teammates via company login
Invite people by name. They sign in once with a passkey, and every app they are allowed to use already knows who they are. No per-app passwords, no broken public URL. Access starts locked and is granted per app.
Keep data on your workspace
Your app runs on your own private Croft server, with an app database (SQLite), continuous encrypted backups, and practised restores. Data stays yours—export everything (code, database, files) and run it anywhere Docker does.
No public deploy by default
Every app sits behind your login before a single line of its code runs. It cannot ship a broken auth page because it does not contain one—the login is the platform's job, not the vibe-coded prototype's. Share intentionally, not by accident.
Connect your assistant to Croft, describe the app, and deploy. The AI builds it; Croft keeps it running and safe. You stay in the part you are good at: having the ideas and making the calls.

FAQ
Frequently asked questions
Which model is best for vibe coding?
As of early October 2026, Claude Sonnet 5.5, Claude Fable 5, Claude Opus 5.5, GPT-6 Astra, and Claude Opus 5 lead Vibe Code Bench at 88-92% on end-to-end web app builds. Rankings shift monthly, and the best choice depends on your workflow—Claude excels at artifacts, Cursor at IDE integration, ChatGPT at conversational iteration, and Grok at speed. The hard part after building is hosting the app privately.
Does Croft sell or prefer any AI model?
No. Croft is model-agnostic hosting. Connect Claude, ChatGPT, Cursor, Grok Build, or any MCP-capable assistant and deploy the apps they build onto your private server with company login, database, and backups. We do not resell models or meter AI tokens—you use your own accounts.
What is Vibe Code Bench?
Vibe Code Bench is a public benchmark from Vals.ai that measures how well AI models build complete web applications from natural language descriptions—not just unit tests or single functions. It evaluates realistic end-to-end workflows with authentication, databases, and UI testing, updated regularly as new models release.
How do I share a vibe-coded app with my team privately?
Connect your assistant (Claude, ChatGPT, Cursor, or Grok) to Croft, describe the app, and deploy. Your app lands on your own private server behind company login. Invite teammates by name, grant access per app, and they sign in once to use it—no public URL, no per-app passwords.
Can I use open-weight models for vibe coding?
Yes. Open-weight models like Kimi K3, DeepSeek V4 Pro, and others are closing the gap—Kimi K3 scored 84.96% on Vibe Code Bench v1.1, the first open model to reach the top tier. If you integrate an open model with an MCP-capable client, you can deploy to Croft the same way.
