QuestDB vs Zed
A side-by-side editorial comparison of QuestDB and Zed — release velocity, themes, recent moves, and the top alternatives to consider.
QuestDB vs Zed: at a glance
What is QuestDB?
QuestDB 10.0 ships QWP — a binary protocol unifying ingestion and Arrow reads — while Enterprise 4.0 adds cold storage and hot failover.
QuestDB landed two major releases back to back: 10.0 (open source) and Enterprise 4.0. The central innovation in both is QWP — a binary, columnar wire protocol that handles both data writes and Apache Arrow reads over a single client connection. Enterprise 4.0 layers cold storage on top, aging partitions to object storage while keeping them queryable, and adds hot failover without a restart. The benchmarks are real: 33M rows/s against ILP, 500M rows streamed to Arrow in 2.3 seconds.
What is Zed?
Zed 1.26 adds Pyrefly for Python and debugs WebAssembly from the JavaScript debugger.
Zed 1.26.2 adds Pyrefly as an optional built-in Python language server, an expandable variable tree in debugger hovers and DWARF support so the JavaScript debugger can step through WebAssembly sources. Agent work continues in smaller pieces: ACP configuration defaults now apply only to new conversations, model pickers get better fuzzy search, and thinking controls explain when thinking can't be turned off. The previous week's 1.25 line shrank binaries and gave external ACP agents context compaction.

QuestDB

◆ Current state
QuestDB landed two major releases back to back: 10.0 (open source) and Enterprise 4.0. The central innovation in both is QWP — a binary, columnar wire protocol that handles both data writes and Apache Arrow reads over a single client connection. Enterprise 4.0 layers cold storage on top, aging partitions to object storage while keeping them queryable, and adds hot failover without a restart. The benchmarks are real: 33M rows/s against ILP, 500M rows streamed to Arrow in 2.3 seconds.
◆ Where it's heading
QuestDB is positioning itself as the time-series database that fits into modern lakehouse architectures without requiring ETL. QWP + Arrow + cold storage + Iceberg compatibility all point toward a single goal: a streaming time-series engine that speaks natively to Parquet-based analytics stacks. The blog post explaining Parquet/Iceberg positioning is the clearest signal — the team is selling to data engineers building lakehouses, not just ops engineers running dashboards.
◆ Prediction
The cold storage Iceberg integration will deepen with catalog support and query pushdown for Spark and Trino. QWP client libraries will ship for major languages beyond the initial Python/Java coverage.
Zed
5.0DEVOPS
Zed 1.26 adds Pyrefly for Python and debugs WebAssembly from the JavaScript debugger.
◆ Current state
Zed 1.26.2 adds Pyrefly as an optional built-in Python language server, an expandable variable tree in debugger hovers and DWARF support so the JavaScript debugger can step through WebAssembly sources. Agent work continues in smaller pieces: ACP configuration defaults now apply only to new conversations, model pickers get better fuzzy search, and thinking controls explain when thinking can't be turned off. The previous week's 1.25 line shrank binaries and gave external ACP agents context compaction.
◆ Where it's heading
Zed is splitting attention between its agent panel, where ACP agents keep gaining the same session handling as Zed's own, and core editor depth in languages and debugging. Weekly stable releases with community-contributed features and quick model additions remain the pattern.
◆ Prediction
Expect 1.27 next week with more ACP session and model-picker work, plus further debugger and language-server additions.
