Comparison
DBNox’s memory footprint is about 15 MB. DBeaver is a mature Java database client with a much wider engine catalog and a default maximum heap of 1 GB. DBNox also includes compare, migrations, JSON and XML, a terminal, files, containers and a REST client.
Reviewed 28 September 2026
DBeaver is a mature database platform: broad engine support, administration, schema and data compare, tasks, and AI in applicable editions.
DBNox is a newer desktop workbench. The daily database workflows are in the current build, along with a terminal, files, Docker and Podman, a REST client, and JSON and XML editors. Unreleased items on this page are marked Coming Soon or Preview.
DBNox is not trying to match DBeaver's engine catalog. DBeaver remains the wider compatibility choice.
DBNox memory footprint
About 15 MB
DBNox’s application memory footprint is about 15 MB. DBeaver’s maintainers document a default maximum heap of 1 GB in dbeaver.ini (-Xmx1024m). That cap is not an idle measurement, and idle use varies by version and what is open.
DBeaver
Java desktop, 1 GB default max heap
A Java desktop. The 1 GB figure is the documented default heap cap, not a measurement of idle memory.
DBNox’s memory footprint is about 15 MB. It is a Rust and Tauri app with streaming results, paged work and background jobs. DBeaver runs on Java; the documented default maximum heap is 1 GB.
Preview. Generate and explain SQL or a Redis command, read a Visual EXPLAIN plan, and call EXPLAIN, statistics, indexes, locks and sessions. Local Llama and Ollama are available. Cloud providers are OpenAI, Anthropic, MiniMax, OpenRouter and OpenAI-compatible endpoints.
SQL, data, compare, migrations, monitoring, jobs, terminal, SFTP/FTP/S3 files, Docker and Podman, a REST client, and JSON and XML editors.
Schema compare, data compare and versioned migrations ship today. Environment drift, snapshots, query-regression history, index intelligence and data profiling are Coming Soon.
| Capability | DBNox | DBeaver |
|---|---|---|
Memory footprint DBNox figure is the application memory footprint. DBeaver’s 1 GB is the default -Xmx cap in dbeaver.ini, not a measured idle size. | About 15 MB | 1 GB default max heap |
Desktop architecture | Rust + Tauri | Java desktop |
Database breadth DBeaver's catalog is a major strength, largely through JDBC. DBNox documents a shorter validated list and does not claim parity. | Validated list on Databases | Very broad |
SQL editing and data grid | Yes | Yes |
Schema and data compare | Yes | Yes |
Versioned migrations | Yes | Yes |
JSON and XML editors DBNox includes a JSON workbench and an XML editor. DBeaver has JSON support; depth depends on edition and driver. | Yes | Varies |
Terminal, files, containers, REST client DBNox ships these in the workbench. DBeaver's toolset is broader in database administration and narrower as a systems toolbox. | Yes | Varies |
AI generate and explain SQL Both offer AI assistance. DBNox AI is Preview. DBeaver AI availability depends on edition. | Preview | Varies |
Local AI | Local Llama and Ollama | Ollama in applicable editions |
MCP | Preview | Varies |
Production safety controls | Yes | Varies |
Jobs | Yes | Yes |
Drift, snapshots, query regression, profiling Listed on the DBNox roadmap. Not in current builds. | Coming Soon | Varies |
License Do not invent a DBeaver edition price. Check dbeaver.io. | $49 early bird, $99 regular | Community free; paid editions exist |
For everyday SQL, schema exploration, data editing, schema and data compare, and migrations, both are desktop database tools. DBNox also includes JSON and XML editors, a terminal, file transfer, Docker and Podman, and a REST client. Early bird is $49 USD per seat for the first 100 customers. Regular price is $99 USD, paid once. DBeaver is the more mature choice when you need its much broader database catalog and administration depth. DBNox does not claim to cover every engine DBeaver supports.
DBNox’s memory footprint is about 15 MB. DBeaver is a Java application. Its maintainers document a default maximum heap of 1 GB (-Xmx1024m in dbeaver.ini). That 1 GB is a cap, not an idle measurement; actual use depends on the version and what is open. Installed size and startup time are separate from this memory figure.
Both can assist with database work. In DBNox, AI is Preview: generate and explain SQL or a Redis command, analyze a Visual EXPLAIN plan, and investigate with EXPLAIN, statistics, indexes, locks and sessions. Local Llama and Ollama need no cloud key. Writes wait for approval. Items such as query-regression history, data profiling and dialect conversion are not current DBNox features. DBeaver AI and Ollama availability depend on the edition.
DBNox documents PostgreSQL, MySQL, MariaDB, SQLite, MongoDB, Redis, ClickHouse and DuckDB, with SQL Server in preview. Depth varies by engine. DBeaver's catalog is much wider and is the reason to choose DBeaver when an engine is not on the DBNox list.
DBeaver features vary by Community and paid editions. Re-check dbeaver.io before treating this page as current. Last review: 28 September 2026.
