Jacker is not released. You cannot sign up for it, it is not included in any plan you can buy today, and none of what follows is available in a workspace. It is here because it is being built in the open, and because the rows it will occupy already appear on the pricing page.
What is built
Eight parts, each of them working in development. None of them is reachable from a workspace.
Scaffold
Pick from 8 production-ready stacks, React + NestJS, Next.js + Supabase, SvelteKit + Fastify, and more. Jacker generates the deterministic skeleton, wiring, and tooling you need.
Plan
Describe a feature in plain English. Jacker produces a persisted markdown plan in your repo so the team can review scope before any code is written.
Build
Claude Code plans, writes, and edits files across frontend, backend, database, and infrastructure. Freeform chat, bug fixes, and chores all flow through the same engine.
Review
Senior code reviewer, security, frontend, backend, database, and deployment experts run read-only reviews in parallel and feed findings back to the builder.
Workbench
Monaco editor, file tree, git-diff gutter, and a real terminal powered by node-pty. Inspect and refine everything the AI produces without leaving Jacker.
API client
Postman-like request builder with environments, history, and response inspection. Validate your new endpoints immediately.
DevOps
Provider-specific GCP and AWS Terraform, generated from your stack. Run init, plan, apply, and destroy, then refine infrastructure with AI.
Live preview
Auto-install dependencies, boot frontend and backend dev servers, stream logs, and view the running app in an embedded iframe.
