Plexus vs InfluxDB
InfluxDB is a purpose-built time-series database — a fast, well-loved place to store metrics and query them with Flux or InfluxQL. It does that one job well. What it doesn't do is the rest of operating a fleet: you still build ingestion pipelines, dashboards, alert rules, and notification plumbing. Plexus is that whole layer, finished — it includes the time-series store (3-year raw retention, 5-year hourly rollups) and adds auto-generated dashboards, threshold/event/offline monitors with routing, and a per-alert audit trail, so you don't stand up a TSDB and hand-build operations around it.
InfluxDB is a time-series database. InfluxDB is a time-series database you'd build a fleet UI on; Plexus includes time-series storage and ships the dashboards, monitors, and alert history already built on top. This page is written by Plexus, so read it with that in mind — we’ve tried to be straight about where InfluxDB is the better choice. Last updated September 2026.
Plexus stores telemetry in Plexus Time Series. Already storing it in Postgres, TimescaleDB, MySQL or ClickHouse? Plexus can also connect to those and query them live. InfluxDB is a partial connection today: Plexus reads buckets and charts them, but its SQL editor and generated panels don't run against Flux, so an Influx-centric stack gets less out of Plexus than a SQL one.
Capability by capability
● full · ◐ partial · ○ not today
| Capability | Plexus | InfluxDB |
|---|---|---|
Purpose-built TSDB query language (Flux / InfluxQL) If you want a general-purpose TSDB to query directly, that's Influx's strength. | ○ | ● |
Standalone time-series store you run and build on Influx is a database to operate and build on; Plexus is storage with the dashboards and alerts already on top. | ◐ | ● |
Direct, arbitrary querying of raw metrics Influx gives you full query access; Plexus queries through its dashboards, API, and terminal, shaped around operations. | ◐ | ● |
Time-series storage included Plexus includes a store with 3-year raw retention and 5-year hourly rollups; with Influx you run the database. | ● | ● |
Dashboards auto-generated from first ingest Influx has basic visualization; Plexus builds the fleet dashboard from the data that actually lands. | ● | ○ |
Threshold, event, and offline monitors with routing Influx has tasks and basic alerting; Plexus ships monitors with per-monitor Slack and email routing and offline detection for sources that go dark. | ● | ◐ |
Per-alert audit trail with verdict capture Alert lifecycle, timeline, and verdicts are frontend concerns a TSDB doesn't carry. | ● | ○ |
Also connects to a database you already run Plexus can query Postgres, TimescaleDB, MySQL and ClickHouse live, and InfluxDB buckets partly (no SQL panels on Flux). | ● | ○ |
When to pick which
Pick InfluxDB as a standalone time-series database if you want a purpose-built store with its own query language to build your own systems and dashboards on.
Pick Plexus if you want the whole operating layer out of the box — storage, auto-generated dashboards, monitors with routing, and alert history as one product — instead of running a TSDB and building the frontend on top of it yourself.
Pricing
Plexus. Free for up to 3 devices and 7 days of history, no card. Pro is $199 a month: every device, the history you choose, alerts and sharing. 50 GB of readings included, then $0.10 per GB-month. Video is $0.50 per GB-month. No per-seat or per-host charges. See pricing
InfluxDB. InfluxDB 3 Core is free and open source to self-manage. Cloud Serverless is usage-based ($0.0025 per MB written, $0.012 per 100 queries, $0.002 per GB-hour stored) with $250 of free credit. Cloud Dedicated and InfluxDB 3 Enterprise are custom-priced. Their pricing page, read September 25, 2026.
Using both together
Plexus can read InfluxDB buckets and chart them. That connection is partial: Influx speaks Flux and InfluxQL, not SQL, so Plexus's SQL editor and generated panels don't run against it. Teams that want everything can keep InfluxDB as the store and send new devices to Plexus, or move the fleet into Plexus's own storage.
Questions
Is Plexus an InfluxDB alternative?
For a fleet's telemetry backend plus its operations UI, yes. Plexus includes time-series storage and ships dashboards, monitors, and alert history already built, so you don't run a separate TSDB and assemble the rest. If what you want is a general-purpose time-series database to query and build on directly, that's InfluxDB's job, not Plexus's.
Does Plexus store my data, or do I still need InfluxDB?
Plexus includes storage — 3-year raw retention (7 days hot, then S3) and 5-year hourly rollups — so you don't need a separate TSDB. If your data already lives in Postgres, TimescaleDB, MySQL or ClickHouse, Plexus can also connect to those and query them live. InfluxDB is partly supported: Plexus reads buckets and charts them.
What do I get over running InfluxDB myself?
Everything above the raw store: SDK and HTTP ingestion, dashboards that generate themselves from the first data, threshold/event/offline monitors with per-monitor notification routing, a full alert timeline with verdicts, and a plain-language ⌘K terminal — without building or operating any of it.
