The short version

  • Only Height has a free tier, so it costs nothing to try first.
  • Each has a real cost: GNAT Pro no pricing published on website; requires contacting AdaCore directly for quotes; Height it is one product from one small venture-funded company with no second line of business underwriting it, so adopting it as your system of record is a bet on that company's funding, and the tool holds work history you would have to reconstruct elsewhere if the bet fails.
  • 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.

GNAT Pro

  • No pricing published on website; requires contacting AdaCore directly for quotes
  • Vendor indicates per-user, per-year subscription model but does not disclose specific costs

Height

  • It is one product from one small venture-funded company with no second line of business underwriting it, so adopting it as your system of record is a bet on that company's funding, and the tool holds work history you would have to reconstruct elsewhere if the bet fails.
  • The 2024 relaunch as Height 2.0 reoriented the product around AI agents and changed workflows customers had already built on, which is the clearest available evidence of how much the product may be re-shaped again under you.
  • The ecosystem is small next to Jira, Linear and Asana: fewer third-party integrations, no consultancy market, and far less written material to search when something behaves unexpectedly, so support questions go to the vendor and wait.
  • The automation only pays off if tasks contain enough substance for a model to work with; on a team whose tickets are two-word titles, the agents have nothing to triage or deduplicate and the product reduces to an ordinary tracker at a premium.
  • Task content is processed by hosted large language models, so a security review becomes a question about subprocessors and data handling, and there is no self-hosted or on-premises deployment to fall back on if the answer is unacceptable.
  • There is no widely used two-way synchronisation with Jira, so an organisation where one team adopts Height and the rest stay on Jira ends up with two systems of record and manual reconciliation between them.

Answered from the vendors’ own pages

GNAT Pro: How much does GNAT Pro cost?

GNAT Pro pricing is not published on the website. Customers must request a pricing quote by contacting AdaCore directly or speaking with a GNAT Pro expert.

Source
Height: How is this different from Jira automation?

Jira automation is rule-based: you define a trigger and an action. Height's agents read the content of tasks and act on judgement, such as recognising that two tickets describe the same bug, which no rule can express.

GNAT Pro: What is GNAT Pro licensing model?

GNAT Pro is sold on a per-user, per-year basis with no license locks. Customers can request pricing for their specific needs.

Source
Height: Can we self-host it?

No. It is software as a service only, with no on-premises or private-cloud deployment. If your requirements rule out a hosted tracker, this is not a candidate.

Height: What happens to our data if the company fails?

You would need an export and a migration to another tool. This is the standard risk with a single-product startup, and it is worth confirming the export path covers task history, comments and custom fields before committing to it.

Height: Does it work for non-engineering teams?

Yes, the views and custom fields are generic enough for marketing, operations or support queues. Its integrations, though, are aimed at software teams, so a non-engineering team gets less of the surrounding value.

Height: Do the AI features need our tickets to be well written?

In practice, yes. Triage, deduplication and attribute maintenance work from what is written in the task, so the return is much higher on a team that already writes descriptive tickets than on one that does not.
