AgentFast gives you the production layer for AI apps out of the box: auth, billing, embeddable chat, API/webhooks, run logs, cost caps, and a polished Next.js dashboard already wired.
Start from an opinionated template, customize the runtime, and ship faster without rebuilding the boring infrastructure.
Builder is $199 at launch and increases to $249 when the public release opens.
Start from a polished template instead of a blank repo
Wire your prompt, tools, and product logic into the runtime
Test runs before launch with schema, logs, and cost guardrails
Ship to widget, API, or webhook with a real dashboard behind it
Everything after the demo is already built.
Auth + billing
User accounts, paid plans, API keys, and Stripe plumbing included
Multi-model runtime
AI SDK + AI Gateway support so you can route across major model providers
Embeds + endpoints
Ship to widget, API, and signed webhooks from the same codebase
Run testing
Schema-aware test runs, sample payloads, and prompt iteration before launch
Ops dashboard
Run logs, analytics, publish/draft controls, and cost visibility
Guardrails
Rate limits, token caps, approvals, replay-safe webhooks, and row-level security
From starter kit to shipped AI product without rebuilding the production layer.
Choose an opinionated template for the product surface you want to ship first: widget, API, or webhook-driven workflow.
Customize prompts, tools, models, and run config, then validate behavior with test runs, sample payloads, and cost limits.
Ship the widget or endpoints, then monitor runs, failures, and usage from the dashboard instead of stitching together admin tooling later.
Each template showcases a real product surface so you can start shipping instead of deciding from a blank form.
Mode: Widget + Chat
Launch a docs-grounded assistant with suggested prompts, publish controls, and a branded embed surface.
Mode: API + Webhook
Start from a structured research workflow that accepts payloads, runs tools, and returns clean output for product features.
Mode: Webhook + Slack
Ship an internal workflow that receives events, runs an agent with guardrails, and pushes structured summaries to the team.
AgentFast is for technical founders who already know what they want to build and are tired of spending the next two weeks on the same production plumbing every time.
The starter kit closes that gap: scaffold faster, launch with real controls, and iterate from actual runtime data.
Ship the product idea, not the missing infrastructure.
AgentFast treats your AI feature like a real product from day one, with runtime, channels, billing, and operational tooling in the same codebase.
Start from an opinionated template with the runtime, UI, and product surfaces already wired.
Launch to widget, API, and signed webhooks with auth, billing, and publish controls included.
Review logs, analytics, costs, and runtime failures so the first release can survive real usage.
AgentFast covers the parts founders keep rebuilding around the AI feature itself: shipping surfaces, monetization hooks, guardrails, and operational visibility.
Free demos are great for proving a prompt. AgentFast is for shipping the product around it.
| AgentFast | Free demos / starter templates | Build from scratch | |
|---|---|---|---|
| Time to first paid prototype | Minutes | Fast demo, missing product layer | Days to weeks |
| Shipping surfaces | Widget + API + webhook | Usually one demo surface | You build each channel |
| Auth + billing hooks | Included in the app shell | Rare | You wire it all yourself |
| Run analytics | Run logs, success, tool usage, cost | Usually minimal telemetry | You build analytics |
| Guardrails | Cost caps, rate limits, approvals | Depends on the template | Custom implementation |
| Operational control plane | Test -> publish -> measure | You add it later | Depends on what you build |
The goal is not to prove an LLM call works. It is to ship the first version that can survive real traffic, billing, and iteration.
Commercial-ready foundation
Sell it
Auth, billing hooks, API keys, and a polished dashboard help you ship something customers can actually pay for.
Multiple product surfaces
Ship more than chat
Widget, API, and webhook surfaces make it easier to package a real product instead of a single chat demo.
Runtime visibility included
Operate it
Run logs, publish controls, analytics, and cost guardrails give you the control plane that usually gets bolted on too late.
Early customers lock in launch pricing before the public release. Buy once, customize the codebase, and ship faster than you would from scratch.
For solo founders shipping a single AI product fast.
Launch pricing. Increases to $249 at public release.
For studios or teams building multiple AI products.
Launch pricing. Increases to $599 at public release.
Launch pricing is reserved for early customers and increases when the public release opens.
A production-ready Next.js starter kit for building and shipping AI products with auth, billing, embeds, API/webhooks, run logs, testing, and guardrails already in place.
Technical founders, indie hackers, and small product teams who want to ship an AI product fast without rebuilding the production layer around it.
The starter kit includes the app shell, dashboard, starter templates, embeddable chat, API/webhook execution paths, auth, billing hooks, analytics, and operational guardrails.
Widget, API, and signed webhook flows are all built in, so you can start with the surface that matches your product idea instead of wiring them one by one.
Yes. You can customize prompts, models, tools, schemas, limits, and deploy settings from the builder and then extend the codebase directly.
Run tester, sample payloads, publish/draft controls, cost caps, rate limits, signed webhooks, and run history with status and error visibility are already included.
This page is for the starter kit itself: a production-ready codebase you customize and deploy for your own product.
You complete checkout, land on the launch access page, submit the GitHub username that should receive the invite, and then get access to the private repo.
Yes. Builder is $199 at launch and moves to $249 at public release. Unlimited is $499 at launch and moves to $599 when the public release opens.
No. This is a digital code product, so all sales are final once repo access has been granted. Use the docs and preview dashboard to evaluate it before buying.
