The short version

  • Only Apache Solr has a free tier, so it costs nothing to try first.
  • Each has a real cost: Aha! sold as eight separate products rather than one subscription, so Roadmaps, Discovery, Ideas, Whiteboards, Builder, Develop, Teamwork and Knowledge are each priced per user; Apache Solr xML-heavy configuration and a developer experience that feels dated beside newer engines
  • They diverge on capability: Aha! covers Strategic roadmaps, Apache Solr covers Lucene-based indexing.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

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

Aha!

  • Sold as eight separate products rather than one subscription, so Roadmaps, Discovery, Ideas, Whiteboards, Builder, Develop, Teamwork and Knowledge are each priced per user
  • Roadmaps at $59 per user per month is expensive next to general project tools, and Discovery and Ideas add $39 each
  • The Develop integration with Roadmaps requires the Enterprise or Enterprise+ tier
  • Annual billing is by invoice only; monthly is card

Apache Solr

  • XML-heavy configuration and a developer experience that feels dated beside newer engines
  • SolrCloud depends on ZooKeeper, adding a component Elasticsearch removed years ago
  • Smaller mindshare now, so newer tutorials, hiring and integrations favour Elasticsearch
  • Considerably heavier than a purpose-built application search engine
