Appsmith vs QuestDB

Appsmith vs QuestDB: at a glance
What is Appsmith?
Appsmith kills its own AI datasource and puts the AI assistant in the product instead
v2.3 does two things at once: it ends Appsmith AI datasources — no new ones after the upgrade, existing ones dead on September 30, 2026 — and ships a native AI Copilot for Custom Widgets plus Ask AI in the Community Edition. Around that sit ordinary builder increments: a Card widget with a composable body canvas, Button label styling, a shared tabOrder for keyboard navigation, and a configurable HTML lang attribute. The releases before it were dominated by CVE remediation and the MongoDB 7 / Java 25 re-platform in v2.0.
What is QuestDB?
QuestDB 10.0 collapses ingest and egress into one binary protocol, then aims at agent-run notebooks.
QuestDB's feed mixes release notes, engineering deep dives and customer stories, and the through-line for the past month has been QWP — its own binary columnar wire protocol. It shipped in 10.0, was benchmarked against InfluxDB Line Protocol on ingestion and against ClickHouse and TimescaleDB on Arrow reads, and now has a standalone explainer covering bidirectional dataframe transfer and built-in failover. Between the protocol posts sit JIT compiler internals and production references from banks and exchanges.

Appsmith kills its own AI datasource and puts the AI assistant in the product instead
◆ Current state
v2.3 does two things at once: it ends Appsmith AI datasources — no new ones after the upgrade, existing ones dead on September 30, 2026 — and ships a native AI Copilot for Custom Widgets plus Ask AI in the Community Edition. Around that sit ordinary builder increments: a Card widget with a composable body canvas, Button label styling, a shared tabOrder for keyboard navigation, and a configurable HTML lang attribute. The releases before it were dominated by CVE remediation and the MongoDB 7 / Java 25 re-platform in v2.0.
◆ Where it's heading
The AI story is being rebuilt one layer up. Instead of AI reachable as a datasource you wire into a query, it is becoming an assistant embedded in the authoring experience — Ask AI stubs appeared in v2.0, and v2.3 makes it real and gives it to the free tier. Meanwhile the security-fix volume that defined v1.98 through v2.1 has thinned, which suggests the hardening backlog opened by the re-platform is largely worked off and feature capacity is returning.
◆ Prediction
Expect the Copilot surface to widen from Custom Widgets to general app authoring — queries, JS objects, bindings — before the September 30 datasource cutoff makes the old path unusable. The entries do not indicate whether Ask AI in Community Edition stays free once it is past this release.
QuestDB
6.3DEVOPS
QuestDB 10.0 collapses ingest and egress into one binary protocol, then aims at agent-run notebooks.
◆ Current state
QuestDB's feed mixes release notes, engineering deep dives and customer stories, and the through-line for the past month has been QWP — its own binary columnar wire protocol. It shipped in 10.0, was benchmarked against InfluxDB Line Protocol on ingestion and against ClickHouse and TimescaleDB on Arrow reads, and now has a standalone explainer covering bidirectional dataframe transfer and built-in failover. Between the protocol posts sit JIT compiler internals and production references from banks and exchanges.
◆ Where it's heading
The protocol work is the thread that matters. QuestDB has been positioning against InfluxDB Line Protocol on ingestion throughput for a while, and 10.0 turned that from a benchmark argument into the default path both in and out of the database. The follow-up posts are consolidation rather than new capability: the same protocol re-explained for a different reader each time, which is what a project does when it needs an ecosystem to adopt a format. Live views and agent-driven notebooks remain the less-proven half of the release.
◆ Prediction
Expect client libraries and third-party connectors to be the next visible work, since a proprietary wire protocol is only worth its switching cost once the dataframe tools speak it. Whether live views leave beta is not something these entries settle.
