Everything you need.
Nothing you don't.

A grid of features. Read top-to-bottom — pricing tiers labeled inline.

GPU-rendered grid

Virtualized, 1M rows, transform-only scroll. The grid is a Metal/DirectX/Vulkan surface, not a DOM table.

Bring-your-own AI

BYOK

Plug in Ollama, the claude CLI, an Anthropic / OpenAI key, or any MCP server. AI usage is billed by your provider, not by zolt.

SSH tunneling, built-in

Define a bastion once. zolt opens, holds, and tears down the tunnel per session. No PuTTY, no autossh dance.

Keychain-backed credentials

Passwords live in macOS Keychain, Windows Credential Manager, or Linux Secret Service. Zolt does not store them in plaintext config files.

E2E-encrypted team sharing

TEAM

Shared payloads are sealed with age to each member's X25519 recipient. The sync server stores ciphertext and workspace metadata, not decryptable connection secrets.

Schema diff & DDL gen

Diff two schemas, generate the migration, paste into your repo. No external diff tool.

MCP server mode

BYOK

Run zolt as a Model Context Protocol server. Claude Desktop calls query_database and describe_schema directly. Tool-use trace, not a chat about your data.
