Spark

AI-native developer workspace that plans, edits, tests, and ships code — with guardrails.

Built on VS Code | Roadmap | Architecture | Security

What is Spark?

Spark is a VS Code fork enhanced with an AI-native workflow engine (SparkCore) that understands your intent, breaks down tasks, generates code and tests, and helps you ship faster — all while keeping your code local-first by default.

North-Star Metric

Shipped Value Rate (SVR): AI-assisted merges per active developer per week.

Activation Target

First plan → diff → tests → PR in ≤20 minutes.

Quickstart

Editor (VS Code fork)

Follow the existing VS Code build instructions to build the editor.

Landing page

cd apps/www
npm install
npm run dev

Contributing

Branch Conventions

• feat/<scope>-<slug> for new features
• fix/<slug> for bug fixes
• chore/<slug> for infrastructure/tooling

Commit Conventions

Use Conventional Commits:

• feat: new capability
• fix: bug fix
• chore: tooling, dependencies, refactor
• docs: documentation only

Pull Requests

• Small, single-purpose PRs
• CI must pass (lint, typecheck, test, build)
• PRs required to merge to main

See the existing VS Code contribution guide for editor-specific guidelines.

Milestones

• Q4 2025: Repo Graph v1, chat+diff, TestGen; private alpha
• Q1 2026: SparkPilot v1, local sandbox; Pro pricing
• Q2 2026: Planner v2, Lens traces, rollbacks; 1.5k WAD, $10k MRR
• Q3 2026: Incorporation (3k WAD, $25k MRR, D30 ≥ 35%)

See ROADMAP.md for details.

VS Code Foundation

Spark is built on the VS Code OSS foundation. The core editor retains all VS Code capabilities, with SparkCore layered on top for AI-native workflows.
