Archseed

Architecture-first · CLI-first · Works with your coding agent

Plan the project before your coding agent defines it for you.

Archseed helps you clarify scope, non-goals, architecture, and constraints before implementation starts — then generates agent-ready context for your preferred coding workflow.

Install
npm install -g @archseed/cli
archseed init

Featured on CodeHype

Built for: TypeScript · Next.js · Node.js

Works alongside: Cursor · Claude Code · Codex · Gemini CLI · OpenCode

Current focus: TypeScript + Next.js projects.

Tool names describe workflows you can use with Archseed. They are not official partnerships or native integrations.

Quick start

Try it on your next project

bash
npm install -g @archseed/cli
mkdir my-project && cd my-project
archseed init

Answer a focused set of questions about V1 scope, non-goals, constraints, technical decisions, assumptions, and edge cases. Archseed saves the result inside your repository so your coding agent starts with clearer direction.

Install docs

Generated in your repository

.archseed/
├── architecture.md
├── implementation-plan.md

└── guardrails.md

Start by giving .archseed/agent-context.md to your coding agent before implementation.

Agent context

A compact brief, not a full architecture document.

.archseed/agent-context.md
# Agent Context — Appointment Booking SaaS

## V1 scope
- Providers publish availability
- Clients book available slots
- Calendar sync prevents double-booking

## Non-goals
- Payments
- Marketplace discovery
- Multi-tenant organizations
- Native mobile app

## Constraints
- Reuse approved booking states
- Do not add integrations outside V1
- Ask before introducing new dependencies

This is not a prompt template. It is durable project context stored with your repository.

How it works

Three steps before implementation.

Clarify the project, write the handoff into the repository, then build with the coding agent you already use.

  1. 01

    Clarify the project

    Define the problem, V1 scope, non-goals, constraints, decisions, assumptions, and unresolved questions before code is generated.

  2. 02

    Create the project handoff

    Archseed writes architecture, implementation, guardrail, decision, and agent-context files inside your repository.

  3. 03

    Build with your preferred agent

    Use Cursor, Claude Code, Codex, Gemini CLI, OpenCode, or your existing workflow. Give the agent clear context instead of a vague prompt.

Use both. Your coding agent writes the feature. Archseed helps make sure the feature starts with clear scope, boundaries, and decisions.

FAQ

Straight answers before you start.

Archseed complements your coding agent. It does not try to replace it.

Is Archseed another AI IDE?
No. Archseed is not an editor and does not replace your development environment. It is a CLI-first, IDE-agnostic workflow for clarifying scope, non-goals, architecture decisions, and constraints before implementation starts.
Does Archseed write my code?
Archseed is not designed to be your primary code-writing tool. It helps you guide discovery, capture decisions, define scope, and generate structured context for the coding agent you choose. Implementation remains in your preferred editor and coding-agent workflow.
Which coding agents work with Archseed?
Archseed is designed to work alongside prompt-driven coding agents and IDE workflows, including Cursor, Claude Code, Codex, Gemini CLI, OpenCode, and similar tools. It does not require a specific editor.
Why not use the plan mode in Cursor or Claude Code?
You can, and plan modes are useful. Archseed focuses on making scope, non-goals, constraints, and architecture decisions more deliberate and reusable across agents, sessions, and implementation phases. The goal is not just a task plan; it is durable project context.
Is this useful for solo developers?
Yes. Archseed is designed for developers who want enough structure to avoid expensive detours without introducing heavy process. It is especially useful for MVPs, SaaS products, client portals, dashboards, CRMs, automations, and internal tools.
Is this useful only for new projects?
The public beta is strongest for new and early-stage projects, and for new features that need clear scope before implementation. A separate workflow for existing Next.js + TypeScript repositories is being tested privately and is not part of the public beta.
What does Founder Beta include?
Founder Beta includes the current architecture-first workflow for new and early-stage projects: guided discovery, scope definition, non-goals, architecture and technical constraints, structured project artifacts, and agent-ready implementation context.
Why is it $12/month during beta?
The Founder Beta price is intentionally simple for solo developers, freelancers, indie hackers, and small technical teams. It supports an early group of committed users who test Archseed on real work and help shape the product.
Will Founder Beta pricing remain available?
Founder Beta pricing may be limited as the product evolves. If you join at $12/month, your price stays locked while you remain subscribed.
How do I give feedback?
Use the feedback link inside the product or reply through the launch channel where you found Archseed. Specific feedback about the project you planned, what became clearer, what was missing, and whether you would return is especially useful.

Install the CLI and plan the next project.

Run archseed init, then give .archseed/agent-context.md to the coding agent you already use.
