The short version

  • Each has a real cost: Hotjar website performance impact - Hotjar tracking code can cause noticeable slowdowns affecting site speed and Google rankings; TiDB a production cluster needs several placement driver, storage and SQL nodes before it is fault tolerant, so the minimum viable footprint is far larger than a MySQL server and TiDB is never the economical choice for a small database.
  • They diverge on capability: Hotjar covers Heatmaps, TiDB covers MySQL wire compatibility.
  • Prices and features above were last checked on 30 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

Hotjar

  • User behavior analysisnot TiDB
  • Conversion optimizationnot TiDB
  • UX researchnot TiDB
  • Customer feedbacknot TiDB
  • Usability testingnot TiDB

TiDB

  • A MySQL workload that has hit the write ceiling of a single primary and would otherwise need an application-level sharding layernot Hotjar
  • Reporting that must run against current transactional data, where the columnar replica removes the delay and the cost of an ETL pipelinenot Hotjar
  • Multi-region deployments needing a single logical database with automatic failover rather than manual primary promotionnot Hotjar
  • Migrating off a sharded MySQL estate where the sharding logic in the application has become the main source of bugs and operational toilnot Hotjar

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Hotjar

  • Website performance impact - Hotjar tracking code can cause noticeable slowdowns affecting site speed and Google rankings
  • Session recording limits - free and lower-tier plans have monthly session recording caps that must be sampled above the limit
  • Inaccurate heatmaps on dynamic pages - heatmaps fail to display correctly on pages with modals, sticky navigation bars, and pop-up overlays
  • No mobile app - only web-based access available
  • Not real-time analytics - includes slight data processing delay

TiDB

  • A production cluster needs several placement driver, storage and SQL nodes before it is fault tolerant, so the minimum viable footprint is far larger than a MySQL server and TiDB is never the economical choice for a small database.
  • Every transaction takes a timestamp from the placement driver and crosses the network to storage nodes, so simple point queries are slower than on single-node MySQL and latency-sensitive paths need to be measured, not assumed.
  • MySQL compatibility is at the wire and dialect level but not complete; stored procedures, triggers and events are not supported, so an application that pushed logic into the database cannot simply be repointed.
  • The columnar replica is an extra full copy of the data on its own nodes, so hybrid analytics roughly doubles storage and adds hardware that must be sized and paid for separately.
  • Operating it well requires cluster-specific expertise in TiUP or the Kubernetes operator, region hot spots, and rebalancing behaviour, so the licence is free but the running cost includes an engineer who understands distributed storage.

Answered from the vendors’ own pages

Hotjar: Does Hotjar have a free tier?

Yes. Hotjar's free plan (now under Contentsquare) includes 200,000 monthly sessions, 10,000 session replays, and unlimited heatmaps, with no time limit on the free tier.

Source
TiDB: Is TiDB a drop-in replacement for MySQL?

At the protocol and dialect level it is close, and most applications connect unchanged. Stored procedures, triggers and events are not supported, and latency characteristics differ, so it needs testing rather than assumption.

Hotjar: Can I export my data from Hotjar?

Yes. Hotjar allows exporting heatmaps as JPG images, survey responses as CSV files, and session recording metadata. Advanced export options are available through the Hotjar API.

Source
TiDB: What licence is it under?

Apache 2.0, for both TiDB and the underlying TiKV storage engine. TiKV is a graduated CNCF project, which is a meaningful governance signal in a market where several competitors moved to source-available licences.

Hotjar: Does Hotjar provide real-time analytics?

No. Hotjar has a slight delay in data processing and does not offer true real-time analytics compared to some competitors.

Source
TiDB: Do I need TiFlash?

Only for analytical queries. It is an optional columnar replica; without it TiDB is a distributed transactional database. With it you get analytics on live data at the cost of an additional full copy.

Hotjar: What integrations does Hotjar support?

Hotjar integrates with Google Analytics, Google Tag Manager, Slack, HubSpot, Jira, Linear, Microsoft Teams, Zapier, and hundreds of other tools through its API and partner integrations.

Source
TiDB: Is the managed cloud the same software?

TiDB Cloud runs the same engine, with the control plane, scaling and operational tooling provided as a service. The entry tier is metered differently from a dedicated cluster, so the cost model rather than the engine is what changes.

TiDB: When is TiDB the wrong choice?

When the database is small enough for one server, when latency on single-row lookups is the primary constraint, or when the application depends on MySQL stored procedures and triggers.
