The short version
- Each has a real cost: Rocket Matter trust accounting compliance is only included on the most expensive Elite tier, so firms with a regulatory requirement for it face a higher effective floor price than the entry-level plan suggests.; Westlaw firms of 11 or more attorneys, which is most firms actually spending serious money on Westlaw, get no published price at all and negotiate blind against a sales team that sees every prior deal.
- They diverge on capability: Rocket Matter covers Matter management, Westlaw covers Case law and statute database.
- Prices and features above were last checked on 1 September 2026.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Rocket Matter
- Trust accounting compliance is only included on the most expensive Elite tier, so firms with a regulatory requirement for it face a higher effective floor price than the entry-level plan suggests.
- It is not built for large enterprise legal departments, so firms above a certain size outgrow it and move to platforms such as Clio or Aderant.
- The tier structure gates common workflow features like kanban boards and templates behind Pro and above, so the cheapest tier is functionally limited.
- Its name is easily confused with the Matter smart-home connectivity protocol, an entirely unrelated technology, which can cause mismatched search results.
- Per-user monthly pricing across four tiers means a growing firm needs to actively reassess its plan as headcount and accounting needs change, rather than a single plan scaling automatically.
Westlaw
- Firms of 11 or more attorneys, which is most firms actually spending serious money on Westlaw, get no published price at all and negotiate blind against a sales team that sees every prior deal.
- Casetext no longer exists as an independent, cheaper self-serve product; anyone who liked its pricing and simplicity now has to buy into the Westlaw ecosystem, typically at a higher, seat-based cost.
- Multi-year contracts are structurally rewarded with the biggest discounts, which pressures firms into 2 or 3 year commitments before they know if usage will justify the tier chosen.
- Content and features vary meaningfully between Edge and Advantage, so an apparently small monthly price difference can hide the absence of Practical Law, which many firms end up needing anyway.
- Switching away from Westlaw means retraining staff on Lexis search syntax and the Key Number System has no direct Lexis equivalent, which is a genuine cost that suppresses competitive shopping at renewal.
