The short version

  • Only Height has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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.; Postscript carrier pass-through fees are billed on top of the per-message rate, roughly $0.00418 per SMS and $0.00841 per MMS in the United States, and are routinely missing from the cost comparisons buyers build.
  • They diverge on capability: Height covers Autonomous triage, Postscript covers Shopify segmentation.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

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.

Postscript

  • Carrier pass-through fees are billed on top of the per-message rate, roughly $0.00418 per SMS and $0.00841 per MMS in the United States, and are routinely missing from the cost comparisons buyers build.
  • The cheapest per-message rates require the $500 a month plan, so a small sender pays more than double the headline low rate per text.
  • The $0 Starter plan carries a $49 minimum monthly spend, so it is not a free tier and quiet months still generate a bill.
  • US SMS marketing carries real legal exposure under consent, quiet hours and carrier registration rules, and the compliance obligation sits with the merchant, not the platform.
  • It is SMS and MMS only, so email, push and on-site messaging live in a separate tool and audience suppression between the two has to be managed across systems.

Answered from the vendors’ own pages

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.

Postscript: Is Postscript only for Shopify?

It is built for Shopify and that is where its segmentation advantage lies, but headless and non-Shopify stores are supported through an SDK with more setup work.

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.

Postscript: What is the real cost per text?

The plan rate plus carrier fees. On Starter that is about $0.015 plus roughly $0.00418 in US carrier fees per SMS, so budget close to two cents a message before discounts.

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.

Postscript: Is the Starter plan free?

No. The base fee is $0 but there is a $49 minimum monthly spend, so it functions as a $49 floor.

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.

Postscript: Do I need a contract?

No. Contracts are offered but not required, and plans can be moved up or down at any time under usage-based billing.

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.
