ApexCharts vs Cortex

ApexCharts vs Cortex: at a glance
What is ApexCharts?
Licensing settled, ApexCharts is back to changing what a chart can take as input.
ApexCharts is deep into a fast v6 line, shipping roughly weekly. The licensing arc that dominated 6.5 through 6.7 — trial watermarks, the first premium-gated chart type, then entitlement checks — has settled, and the last three releases are library work again. 6.9.0 is the largest of them: a histogram type that bins raw samples, a morph engine that conserves marks across chart types, and the end of the library's dependency-free packaging.
What is Cortex?
Cortex is betting on Parquet block storage and graduating years of experimental features.
Cortex publishes its release notes as release candidates, and the two majors visible here tell a consistent story. 1.20 introduced Parquet-based block storage, Prometheus Remote Write 2.0, a resource-based limiter for ingesters and store-gateways, and regex tenant resolution, all experimental. 1.21 then made Parquet a Store Gateway query mode, graduated the Ruler API, Alertmanager API and sharding, tenant federation, FIFO/Redis cache and memcached service discovery out of experimental, and enabled the bucket index by default. The 1.21.1 candidate is almost entirely security hardening.

ApexCharts
10.0ANALYTICS
Licensing settled, ApexCharts is back to changing what a chart can take as input.
◆ Current state
ApexCharts is deep into a fast v6 line, shipping roughly weekly. The licensing arc that dominated 6.5 through 6.7 — trial watermarks, the first premium-gated chart type, then entitlement checks — has settled, and the last three releases are library work again. 6.9.0 is the largest of them: a histogram type that bins raw samples, a morph engine that conserves marks across chart types, and the end of the library's dependency-free packaging.
◆ Where it's heading
The through-line now is input and arrangement rather than catalogue size. Charts increasingly accept the measurements a team actually has instead of pre-aggregated values, and the seams that let you hand a chart its own layout — plotOptions.unit.positions, the pluggable layout hook — are being filled in with kits rather than hard-coded options. The premium boundary has stopped moving; the free catalogue keeps growing around it.
◆ Prediction
Expect the raw-observation pattern to reach another chart type now that the bar pathway handles binning, and expect the remaining pluggable seams to get companion kits the way positions just did.
Cortex
0.0ANALYTICS
Cortex is betting on Parquet block storage and graduating years of experimental features.
◆ Current state
Cortex publishes its release notes as release candidates, and the two majors visible here tell a consistent story. 1.20 introduced Parquet-based block storage, Prometheus Remote Write 2.0, a resource-based limiter for ingesters and store-gateways, and regex tenant resolution, all experimental. 1.21 then made Parquet a Store Gateway query mode, graduated the Ruler API, Alertmanager API and sharding, tenant federation, FIFO/Redis cache and memcached service discovery out of experimental, and enabled the bucket index by default. The 1.21.1 candidate is almost entirely security hardening.
◆ Where it's heading
Two arcs run in parallel. The storage arc is moving Cortex off pure TSDB blocks toward Parquet, first as a converter and format, then as a queryable Store Gateway mode — the same columnar direction the rest of the observability market has taken for long-retention data. The maturity arc is a deliberate clearing of the experimental backlog, with six subsystems graduating in one release and their flags renamed to drop the experimental prefix. Layered on both is a distinct hardening push: the latest candidate bounds gossip connections, caps decompressed request bodies, adds HMAC stream authentication and validates tenant IDs against the authenticated caller.
◆ Prediction
Expect Parquet to keep progressing from experimental toward default, following the path the bucket index just completed. The security work in 1.21.1 reads like a systematic pass over untrusted input paths rather than a response to a single report, so more of the same in the ingestion and gossip layers is likely.
