QueryForge — The AI SQL Editor That Explains and Optimizes Before You Hit Run
DBeaver is a 2009 time machine and DataGrip costs more than your hosting bill. QueryForge is a modern browser-based SQL editor with live query explanation and AI optimization suggestions that do not require a PhD in query planning to understand.

Developers want a modern SQL editor with built-in AI query optimization, as existing tools like DBeaver and TablePlus lack AI features and DataGrip is expensive for small teams.
What is it?
Small teams and startup developers are stuck choosing between free tools with terrible UX and $200/year DataGrip licenses they only use to run three queries a week. QueryForge gives them a clean web-based SQL editor with multi-connection support, a live EXPLAIN plan visualizer, and a Claude-powered optimization panel that reads your slow query and tells you exactly what index to add and why in plain English. The $29/month team tier covers 5 connections and shared query libraries. Buildable in two weeks because the SQL parsing layer is handled by node-sql-parser, EXPLAIN output is just JSON, and Claude's SQL reasoning is exceptional.
Why now?
The May 2026 wave of Neon, Supabase, and PlanetScale adoption means thousands of small teams have cloud Postgres instances but are still using decade-old desktop tools — and Claude's SQL reasoning just became good enough to replace a senior DBA for 80% of optimization tasks.
- ▸CodeMirror 6 SQL editor with syntax highlighting, autocomplete from live schema, and keyboard shortcuts.
- ▸Visual EXPLAIN plan renderer that turns Postgres JSON output into a readable node tree.
- ▸Claude-powered optimization panel that reads slow queries and suggests specific indexes and rewrites in plain English.
- ▸Shared query library per team with search, tagging, and version history.
Target Audience
Startup developers and small engineering teams of 2-10 people using Postgres or MySQL, estimated 200,000+ teams globally on Supabase, PlanetScale, Neon, and Railway.
Example Use Case
A 4-person startup team connects their Neon Postgres instance, spots a 3-second query in their shared library, clicks Optimize, and sees Claude recommend a composite index that cuts query time to 40ms.
User Stories
- ▸As a startup backend developer, I want AI-generated index suggestions for my slow queries, so that I can fix performance issues without waiting for a DBA code review.
- ▸As an engineering lead, I want a shared team query library with version history, so that my team stops pasting SQL snippets in Slack threads.
- ▸As a solo founder using Supabase, I want a visual EXPLAIN plan renderer, so that I can understand why my query is slow without reading Postgres documentation for an hour.
Done When
- ✓Connection: done when user pastes a Postgres connection string and sees their live schema tree in the left sidebar within 5 seconds.
- ✓Optimization: done when user clicks Optimize on any slow query and sees a plain-English suggestion with a specific CREATE INDEX statement within 10 seconds.
- ✓Team library: done when user saves a query to the shared library and a teammate can find it by searching the query name.
- ✓Billing: done when Stripe checkout completes and the team connection limit increases from 1 to 5 immediately on the editor page.

Ongoing: Hacker News Show HN, developer Twitter/X, Supabase and Neon Discord communities, SEO on SQL optimization how-to content.
What's the competition?
Competition Level
High
Similar Products
TablePlus is excellent but desktop-only with no AI features. DBeaver is free but 2009 UX with no optimization layer. DataGrip has AI but costs $200/year and requires JetBrains toolchain buy-in.
Competitive Advantage
Browser-based means zero install friction, AI optimization panel is genuinely not in TablePlus or DBeaver, and the team shared query library fills a real gap for 2-10 person teams.
Regulatory Risks
Database credentials stored by the app create significant security liability — must encrypt connection strings at rest, document the security model publicly, and offer credential-free connection string input as an alternative.
What's the roadmap?
Feature Roadmap
V1 (launch): Postgres editor, EXPLAIN visualizer, AI optimize panel, shared query library. V2 (month 2-3): MySQL support, query history search, slow query alerts via email. V3 (month 4+): team roles, query scheduling, Slack integration for query results.
Milestone Plan
Phase 1 (Week 1-2): editor, execute API, EXPLAIN parser, demo connection seeded. Phase 2 (Week 3-4): Claude optimization panel, auth, Stripe billing, 10 beta teams. Phase 3 (Month 2): 30 paying teams, Show HN launch.
How do you build it?
Tech Stack
Next.js, Claude API, node-sql-parser, Supabase, CodeMirror 6 — build with Cursor for query engine, v0 for editor UI components
Suggested Frameworks
-
Time to Ship
3 weeks
Required Skills
CodeMirror 6 integration, database connection management, Claude API prompting, Next.js.
Resources
CodeMirror 6 docs, node-sql-parser GitHub, Claude API docs, Postgres EXPLAIN documentation.
MVP Scope
app/page.tsx (landing + pricing), app/editor/page.tsx (main SQL editor workspace), app/api/optimize/route.ts (Claude optimization endpoint), app/api/execute/route.ts (proxied query execution), lib/db-connect.ts (connection manager), lib/explain-parser.ts (EXPLAIN JSON to tree), lib/db/schema.ts (Drizzle schema for user data), components/Editor.tsx (CodeMirror 6 wrapper), components/ExplainTree.tsx (EXPLAIN visualizer), .env.example (required env vars), seed.ts (demo connection and 5 sample queries).
Core User Journey
Add connection -> schema autocomplete loads -> write query -> click Optimize -> see plain-English index suggestion -> share query to team library -> upgrade to paid.
Architecture Pattern
User inputs connection string -> encrypted in Supabase -> editor fetches live schema -> query submitted -> proxied to target DB -> EXPLAIN output parsed -> Claude API generates optimization suggestion -> result and suggestion rendered in split pane.
Data Model
User has many Connections. Connection has many Queries. Query has one ExplainResult. Query has one OptimizationSuggestion. User belongs to one Team. Team has many Queries.
Integration Points
Claude API for query optimization suggestions, node-sql-parser for query validation, Supabase for user data and encrypted connections, Stripe for billing, Resend for onboarding emails, Vercel for hosting.
V1 Scope Boundaries
V1 excludes: mobile app, query scheduling, data export pipelines, multi-cloud hosting, MySQL support (Postgres only), custom AI model fine-tuning.
Success Definition
A paying team of 3 developers uses QueryForge daily for 30 days, saves one slow query using the AI optimization panel, and renews without any founder prompting.
Challenges
The hardest non-technical problem is convincing developers to trust a new tool with production database credentials — social proof and a clear security page must come before any paid acquisition spending.
Avoid These Pitfalls
Do not proxy query execution through your own server in V1 — let the browser connect directly to reduce latency and eliminate your liability for query results. Do not build a visual schema designer before validating the optimization panel is the actual hook. Finding your first 10 paying teams will take 3x longer than building the editor — start community posting on day one not after shipping.
Security Requirements
Supabase Auth with Google OAuth, AES-256 encryption for stored connection strings, RLS on all user tables, rate limiting 60 queries/min per user, GDPR data deletion endpoint required.
Infrastructure Plan
Vercel for Next.js, Supabase for Postgres and auth, GitHub Actions for CI, Sentry for error tracking, no separate file storage needed.
Performance Targets
200 DAU at launch, query execution proxy under 200ms overhead, optimization API under 8 seconds, page load under 2s, CDN for static assets.

First Run Experience
On first run: a demo read-only Postgres connection is preloaded with 5 sample queries including two deliberately slow ones. User can immediately run queries, view EXPLAIN trees, and click Optimize on the slow queries without entering any credentials. No manual config required: demo connection is read-only and hardcoded, Claude API fires on sample queries out of the box.
How to build it, step by step
1. Define Drizzle schema for User, Team, Connection, Query, OptimizationSuggestion in lib/db/schema.ts. 2. Build lib/db-connect.ts that validates and encrypts Postgres connection strings using AES-256 before storing. 3. Build app/api/execute/route.ts that runs parameterized queries against the stored connection and returns results plus EXPLAIN JSON. 4. Build lib/explain-parser.ts that converts Postgres EXPLAIN JSON into a nested tree structure. 5. Build components/Editor.tsx wrapping CodeMirror 6 with SQL language support and live schema autocomplete. 6. Build components/ExplainTree.tsx rendering the parsed EXPLAIN tree as a collapsible node diagram. 7. Create app/api/optimize/route.ts sending the slow query plus EXPLAIN tree to Claude and returning plain-English suggestions. 8. Add Supabase Auth with Google OAuth and RLS on all user-scoped tables. 9. Wire Stripe $29/month team plan with connection count gating and AI optimization panel toggle. 10. Deploy to Vercel, seed demo connection with 5 sample queries, and verify the full connect-to-optimization journey without any manual database setup.
