The short version

  • Only Rasa has a free tier, so it costs nothing to try first.
  • Each has a real cost: Assembled the published per-agent rate is not the whole bill, because a separate platform fee sits on top and is not published, so the headline 25 USD figure understates the real cost and you still need a quote to know the total.; Rasa free Developer Edition caps conversations at 1,000 external or 100 internal per company per month
  • They diverge on capability: Assembled covers Volume forecasting, Rasa covers NLU engine.
  • Prices and features above were last checked on 31 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

  • A subscription business that wants to measure whether an AI deflection layer actually reduces required headcount, using the same forecasting tool that sizes the human teamnot Rasa
  • A finance team that needs a defensible per-agent cost line for support tooling before a board budget review, without a three-week vendor quoting cyclenot Rasa

Where each one falls short

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

Assembled

  • The published per-agent rate is not the whole bill, because a separate platform fee sits on top and is not published, so the headline 25 USD figure understates the real cost and you still need a quote to know the total.
  • Pricing AI Agents per resolved conversation while pricing workforce management per seat means the two products pull in opposite directions financially: successful deflection shrinks the seat count you are billed for and grows the consumption charge, making year-two budgeting unpredictable.
  • Long-range capacity planning and what-if scenario modelling are thinner than in NICE or Verint, so organisations doing annual headcount planning across multiple sites often end up exporting to a spreadsheet anyway.
  • There is no quality management or agent evaluation module, so a support organisation that wants WFM and QA from one vendor has to buy a second tool and reconcile two sets of agent records.
  • The product assumes a modern ticketing system as the source of truth; teams running a legacy ACD or a homegrown queue face custom integration work that the standard connectors do not cover, and forecast accuracy suffers until that data is clean.
  • There is no native mobile application, so agents check schedules, request time off and swap shifts through a mobile browser, which is a persistent friction point for hourly and contact centre workforces who do not sit at a desk.

Rasa

  • Free Developer Edition caps conversations at 1,000 external or 100 internal per company per month
  • Rasa Pro and the Business Plan (Pro plus Studio) are not priced on the site and require contacting sales

Answered from the vendors’ own pages

Assembled: Does Assembled publish its real total cost?

It publishes per-agent tier rates of 25, 45 and 75 USD per month but adds an unpublished platform fee, so budget for the seat rate plus a fixed annual platform charge that you must ask for.

Rasa: Does Rasa offer a free version?

Yes. Rasa offers a free Developer Edition with one bot per company, up to 1,000 external conversations per month, and free community support.

Source
Assembled: Can I buy the AI agents without buying workforce management?

Yes. Assembled sells WFM, AI Copilot and AI Agents as separately purchasable products, and AI Agents are billed at 0.65 USD per resolved conversation rather than per seat.

Rasa: What support is included with Rasa's free tier?

The free tier includes community forum support with responses from Rasa community members. Paid tiers add premium support with enhanced response times.

Source
Assembled: Is it suitable for a voice-first call centre?

Less so. The forecasting and scheduling are built around omnichannel ticketing volume, and voice-heavy operations running a legacy ACD will find the integration and intraday voice controls weaker than a traditional WFM suite.

Rasa: What is the difference between Rasa Pro and Enterprise?

Rasa Pro includes the pro-code framework with advanced NLU and multi-LLM management. Enterprise adds full platform access, 24/7 support, dedicated Customer Success Manager, and business reviews.

Source
Assembled: How long does implementation take?

Assembled states typically one month or less, which is realistic when your helpdesk is Zendesk or Salesforce and historical data is clean.
