QueryGlow vs HeidiSQL:
Web-Based, Cross-Platform, AI-Powered

HeidiSQL is fast and free on Windows. But its macOS build is officially “early preview”, it has no AI, and it's desktop-only. QueryGlow is web-based, self-hosted, and AI-powered — works in any browser, $79 once for your whole team.

Open in any browser. No install. Works on Mac, Linux, Windows, tablet, phone.

Why developers switch from HeidiSQL to QueryGlow

Works on every device

HeidiSQL is desktop-only with macOS in “early preview”. QueryGlow runs in any browser — laptop, tablet, phone, on any OS.

AI writes your SQL

HeidiSQL has no AI. QueryGlow generates queries from plain English using OpenAI, Claude, or Gemini. Your schema is sent, never your data.

Your data stays yours

QueryGlow is self-hosted. No cloud, no telemetry, no third-party servers. Centralized AES-256-GCM encrypted connections.

Where HeidiSQL Falls Short in 2026

Mac is "Early Preview"

HeidiSQL's macOS build is classified by the project itself as "early preview stage." A February 2026 forum post on the official HeidiSQL site reports the current build as "still unusable."

Zero AI Assistance

HeidiSQL's official feature list has no LLM or AI integration. You write every query by hand — no natural language to SQL, no schema-aware suggestions.

Single-User Desktop

Built for one developer, one machine. Connections are stored locally. Onboarding a teammate means another install. No shared connection management.

No Modern Postgres Extensions

HeidiSQL connects to vanilla PostgreSQL but does not support TimescaleDB (time-series) or CockroachDB (Postgres-compatible distributed). If you use either, HeidiSQL won't connect.

Platform Reality Check

Current platform status for both tools. HeidiSQL classification verified at heidisql.com (May 2026).

The macOS classification “early preview stage” comes from HeidiSQL's own homepage. In a Feb 2026 post on the official HeidiSQL forum, a long-time user reported the current macOS build as “still unusable.”

Desktop App vs Web App

HeidiSQL (Desktop)

Native Delphi/Lazarus application

  • Install per developer, per device
  • Windows is primary; Mac in “early preview”
  • Connections stored locally — not shared
  • No mobile, no tablet access
  • New teammate = new install + new setup
TEAM-READY

QueryGlow (Web)

Deploy once, access from any browser

  • One server install covers your whole team
  • Identical experience on Mac, Linux, Windows
  • Connections centralized & AES-256-GCM encrypted
  • Tablet and phone via responsive web
  • New teammate = just share the URL

Features HeidiSQL Doesn't Have

AI SQL Generation

Describe what you want in plain English. Choose OpenAI, Claude, or Gemini. Use your own API key — no markup.

Web-Based Access

HeidiSQL is a desktop app. QueryGlow is a URL — open it in any browser, on any device, on any OS.

EXPLAIN Visualizer

Visual query plan analysis with color-coded execution times and actionable index suggestions.

TimescaleDB & CockroachDB

HeidiSQL connects to vanilla PostgreSQL only. QueryGlow supports TimescaleDB (time-series) and CockroachDB (distributed) as first-class databases.

Safe Mode

Blocks DROP DATABASE, prevents DELETE/UPDATE without WHERE, auto-limits SELECT to 1000 rows.

Team Connection Sharing

Centralized encrypted connections accessible to your whole team via shared URL. No per-device setup.

Which One Fits You?

Honest framing — there are real reasons to stay with HeidiSQL, and real reasons to switch.

Stick with HeidiSQL If...

  • You work solo on Windows — it's genuinely fast and free
  • You need MS SQL Server, Interbase, or Firebird (QueryGlow does not support these)
  • You strictly need a 22+ year mature project
  • Free ($0) vs $79 is a hard line for you
  • You don't need AI, web access, or team sharing

Switch to QueryGlow If...

  • You're on Mac — or your team mixes operating systems
  • You want AI to write and explain your SQL
  • You share database access with a team
  • You use TimescaleDB or CockroachDB
  • You need to access your DB from a tablet, phone, or any browser
  • You want centralized, encrypted connection management

Your Database, From Any Browser.

Skip the preview builds. Skip the per-device installs. Skip the AI gap. One URL. Whole team. $79 once.
