The short version

  • Each has a real cost: DISCO per-gigabyte pricing that is attractive on a 200 gigabyte matter becomes the dominant line item on multi-terabyte collections, and the only cost lever left is aggressive culling before upload.; 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.
  • They diverge on capability: DISCO covers All-in per-gigabyte pricing, Rocket Matter covers Matter management.
  • 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.

DISCO

  • Per-gigabyte pricing that is attractive on a 200 gigabyte matter becomes the dominant line item on multi-terabyte collections, and the only cost lever left is aggressive culling before upload.
  • Hosting is cloud only in United States regions, so matters with European, United Kingdom or Australian data residency requirements are excluded outright.
  • Review analytics, scripting and the third-party application ecosystem remain deeper on Relativity, which matters for firms with established review workflows.
  • As a listed company reporting losses, it has been through leadership change including the founder departure in 2023, so multi-year roadmap commitments carry more risk than with a private vendor.
  • Complex productions and unusual data types still require professional services, so the promise of self-service holds mainly for mainstream email and document collections.

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.

Answered from the vendors’ own pages

DISCO: How is DISCO priced?

Per gigabyte of hosted data per month, all-in, with unlimited users. There is no published rate card, so it is quoted.

Rocket Matter: Does Rocket Matter include trust accounting?

Only on the Elite tier; the Essentials, Pro and Premier tiers do not include full trust accounting compliance.

DISCO: Can data be hosted outside the United States?

Coverage is centred on United States cloud regions, so confirm residency before shortlisting for European or Australian matters.

Rocket Matter: Is Rocket Matter the same as the Matter smart-home standard?

No, that is an unrelated connectivity protocol for smart-home devices; Rocket Matter is legal practice management software.

DISCO: Is it cheaper than Relativity?

On small and mid-sized matters usually yes, because seats and analytics are included. On very large collections the volume charge often overtakes a negotiated Relativity arrangement.

Rocket Matter: What size firm is Rocket Matter built for?

Solo practitioners through mid-sized firms; larger firms typically need a more enterprise-oriented platform.
