What Does Rasa Actually Cost?

Short answer, up front: Rasa's Developer Edition is free, capped at 1,000 external conversations a month (or 100 a month if only your own employees use it), and it's allowed in production, not just as a demo (rasa.com/pricing). Past that cap, every paid option — Rasa Pro, Business, Enterprise — is listed as "Contact sales," with no public number anywhere on rasa.com.

That's the whole answer in two sentences. The rest of this page is about why it's so hard to find that answer anywhere else, what you actually get at each tier, and what really drives the cost once you're past the free ceiling. Pricing details below were checked directly against rasa.com on 2026-09-26. Rasa can change tiers, caps and wording at any time, so treat what follows as a snapshot, not a contract.

Wait — Which Rasa? A Name Collision Is Wrecking the Search Results

Search "rasa pricing" yourself and the results are, frankly, a mess. A cluster of the top listings — pages from Capterra, TrustRadius, and valuecore.ai among them — aren't about the conversational AI framework at rasa.com at all. They're about rasa.io, a completely different company that sells AI-personalized email newsletters to associations and nonprofits. Same name, two unrelated products, mixed together in one results page.

It gets stranger. One top result is a forum thread literally titled "Rasa pricing inquiries" — evidence the question doesn't have an easy answer anywhere else. Rasa's own homepage ranks first and, as you'll see below, publishes no price beyond the free tier. A review from voiceflow.com, a direct competitor, also shows up prominently. For a less interested read on how the two frameworks compare, our Rasa vs Voiceflow comparison lays out the differences without a sales angle either way.

So to be unambiguous: everything from here down is about Rasa, the open-source-rooted conversational AI framework at rasa.com — the one developers use to build chatbots and voice agents. It has nothing to do with rasa.io's newsletter product, and if you landed here looking for that, this isn't it.

The Free Developer Edition: What You Actually Get

Rasa's no-cost tier is officially called the Developer Edition, and the wording around its limits is worth reading closely because two Rasa pages phrase it slightly differently. The pricing page says: "One bot per company, with up to 1000 external conversations/month or 100 internal conversations/month" (rasa.com/pricing). The license request page puts it this way: "This license is free and valid for up to 1,000 conversation per month (100 if used by your employees)" (rasa.com/rasa-pro-developer-edition-license-key-request). Same rule, two authors — the number that matters is consistent: 1,000 conversations a month for customer-facing use, 100 a month if it's internal-only.

The full legal terms live at rasa.com/developer-terms, and they add detail the marketing pages skip. Each licence key runs "for a licence term of 12 months", renewable on request. You may use it "for one use case, whether internal or external" — a second use case requires a commercial licence. Telemetry "must remain active" and "disabling these features is not permitted". And the licence "is not provided with a technical support package", so support means the community forum and nothing more. None of that is a trick; it's a genuinely free licence with genuinely stated conditions, which is more than most vendors publish.

Can You Run It in Production? Yes — With Real Caveats

A lot of "free tier" chatbot licences quietly mean "development sandbox only." Rasa's doesn't. The licence key page states you can "run it locally on your laptop or deploy it to a development, staging, or production server" (rasa.com/rasa-pro-developer-edition-license-key-request), and the developer terms confirm you can use the product "in a commercial production environment, subject to the usage restrictions below" (rasa.com/developer-terms). So yes — a small support bot handling under 1,000 real conversations a month can legitimately run in production on the free licence, as long as you stay under the cap, keep to a single use case, and renew each year. The moment you cross any of those, you're expected to move to a commercial plan.

Rasa Pro, Business, and Enterprise: The Tiers Nobody Prices Publicly

Once you're past the free cap, Rasa's pricing page stops giving numbers and starts giving forms. Rasa Pro is listed as the standalone pro-code framework tier, with no separate price shown. Layer Rasa Studio on top — a no-code builder, testing panel, content management, conversation analytics, SSO, and role-based access control — and you get the tier Rasa calls Business, available self-managed or as a managed service, with a choice of Basic or Premium support. Go bigger and you land in Enterprise: "Full access to Rasa Platform & Premium Support," large-scale deployment, enterprise security, enhanced automation, and Premium support with 24/7/365 response times and a dedicated success team. Both show the identical call to action: "Contact sales." (rasa.com/pricing)

What Actually Drives the Cost, Since Rasa Won't Say the Number

A word of warning before you go looking: several third-party review sites quote confident-sounding annual figures for Rasa Pro. None of them is published by Rasa, and none that we could find shows how it was obtained. Treat every specific number you see outside rasa.com as hearsay until a quote lands in your inbox. What can be said, reasoning from what Rasa does publish, is which levers move the bill: conversation volume, which is the entire reason the free cap exists; the support tier, since Basic versus 24/7/365 Premium is a real distinction on Rasa's own page; whether Rasa manages the hosting or you run it yourself; and whether you add Rasa Studio's no-code layer. That isn't a price list — it's the set of questions worth making a sales rep itemise instead of accepting one bundled figure.

Is Rasa Still Open Source? The Honest 2026 Answer

This is the correction most comparison pages still haven't made. Rasa's own release and maintenance policy (rasa.com/rasa-product-release-and-maintenance-policy) lists only one version line of the historic Apache-2.0 Rasa Open Source under active maintenance — 3.6.x — and its End of Software Maintenance date was July 3, 2024. Every earlier 3.x release had already passed its own end-of-maintenance date before that.

The policy is blunt about what that means for anyone still running the free open-source line: those dates "only apply to commercial subscriptions," and, in Rasa's own words, "Community (Open Source) users should not expect a similar level of support or commitment to receiving software or security patches from Rasa in accordance with these software maintenance support dates." Active development has moved to Rasa Pro, the commercially licensed edition, distributed on PyPI as rasa-pro. So if someone asks "is Rasa open source," the honest 2026 answer is: not the way it was three years ago. The Apache-2.0 community line is past end of maintenance, and the practical free route today is the Developer Edition licence above — free, but bounded by conversation caps rather than by source-code licensing.

Self-Hosting Rasa: Where the Money Actually Goes

Rasa doesn't publish infrastructure numbers for self-hosting, and it shouldn't — they depend entirely on your traffic, your model choices, and how much Kubernetes experience your team already has. But you can reason about where the money goes. There's compute for the action server and for any models you host yourself. There's DevOps time to keep a deployment patched, scaled, and observable, which is not a line item Rasa controls and not one that shows up in any licence comparison. And if you lean on CALM's language-model-driven flows, the LLM provider's token costs land on your own bill rather than Rasa's — the item evaluators most often forget, because it scales with conversation volume in a way a flat licence fee does not.

If what appeals to you is really a lighter operational footprint rather than the framework itself, it's worth comparing against Botpress, which takes a different hosting approach — our Botpress vs Rasa comparison covers where the two diverge on setup effort.

Rasa and Voice AI

Rasa does sell a voice product, and the claims it makes for it are specific rather than vague. Its voice page promises "sub-second latency from end-of-speech to agent response" and support for "true turn-taking, interruptions, and rephrasing in real time" (rasa.com/voice) — the kind of behaviour that matters in contact-centre and telephony work, where a caller talks over the bot or changes their mind halfway through a sentence. Worth noting what the page does not do: it shows no price, and it doesn't spell out how much of your existing chat configuration carries across to voice. Both are questions for the demo rather than assumptions to make in advance, and voice sits inside the same Developer Edition / Business / Enterprise structure covered above.

Rasa and Multilingual Support

Multilingual handling is one of the more genuinely useful parts of the CALM approach rather than a checkbox. Rasa's multilingual page describes being able to "switch languages naturally while keeping the conversation coherent, personal, and on track", and on the build side to "support multiple languages using shared Flows and logic" and "reuse dialog structures across locales while customizing phrasing where needed" (rasa.com/multilingual-ai). In other words, you maintain one conversation design rather than a parallel copy per language. Notably, Rasa publishes no fixed count of supported languages anywhere on that page — so whether your language is genuinely well served depends on your NLU and model configuration, and it's worth testing against Rasa's current documentation before you commit rather than trusting a number from a comparison table.

Who's Actually Using Rasa

Rasa's own customer page (rasa.com/customers) names, among others, Autodesk, BNP Paribas, Groupe IMA, Swisscom, Providence, SmartRecruiters, JetBrains, Albert Heijn, nib Group, Deutsche Telekom and its Service Desk unit, N26, T-Mobile, Helvetia, PicPay, Raiffeisen, Lemonade, Tia Health and Eddy Travels. It's an enterprise-heavy list of telecoms, banks, insurers and healthcare providers, which fits a product sold through a sales conversation rather than a checkout page — and it's a fair signal that the framework holds up at volume, whatever the licence costs.

How Rasa Stacks Up

Rasa's pitch has always been developer control: you write the dialogue logic in code, own the deployment, and aren't boxed in by a visual builder when a use case outgrows one. That's a trade-off, not a universal win. Teams that want a working bot quickly, without a Python team on staff, more often land on Intercom — our Intercom vs Rasa comparison takes that trade-off head on. Still scoping, and not committed to Rasa specifically? Our broader conversational AI category page rounds up the alternatives worth a shortlist spot before you book any sales call.

Frequently Asked Questions

Is Rasa free?

Yes, in a real but limited sense. Rasa's Developer Edition is free under its own licence, capped at 1,000 external conversations a month (100 if only internal staff use it), one bot per company (rasa.com/pricing). Beyond that cap — higher volume, Rasa Studio, enterprise support — you move to Business or Enterprise, both priced only through "contact sales."

Is Rasa still open source?

Not in the way it used to be. Rasa's own maintenance policy shows the last Apache-2.0 Rasa Open Source line, 3.6.x, passed end of software maintenance on July 3, 2024, and community users "should not expect" the same patch commitment as paying customers. Active development now sits in Rasa Pro, the commercially licensed edition.

What does Rasa Pro cost?

Rasa doesn't say. Rasa Pro, Business and Enterprise are all listed on rasa.com/pricing as "Contact sales," with no published number for any of them. Third-party review sites quote confident annual figures, but none is published by Rasa and none shows its method — treat them as hearsay until you have a written quote.

What's the difference between Rasa and rasa.io?

They're unrelated companies that happen to share a name. Rasa (rasa.com) builds the conversational AI framework this page covers. rasa.io sells AI-personalized email newsletters for associations and nonprofits — nothing to do with chatbots. Several pages ranking for "rasa pricing" are actually about rasa.io, so check the URL before trusting the number.

Can I use the free licence in production?

Yes. Rasa's licence key request page says explicitly you can "run it locally on your laptop or deploy it to a development, staging, or production server", and the developer terms permit use "in a commercial production environment, subject to the usage restrictions". It is capped at 1,000 external conversations a month and one use case.

What are the real costs of self-hosting Rasa?

Rasa doesn't publish infrastructure numbers, since they depend on your traffic and stack. The real drivers are compute for the action server and any self-hosted models, DevOps time to keep the deployment running reliably, and LLM provider token costs if you use CALM's language-model features — those bills go to your own account, not Rasa's.

Does Rasa support voice?

Yes. Rasa's voice page promises "sub-second latency from end-of-speech to agent response" and support for "true turn-taking, interruptions, and rephrasing in real time", aimed at contact-centre and telephony use cases. No separate price is published for voice, and the page doesn't specify how much chat configuration carries over — both are demo questions.

Does Rasa support multiple languages?

Yes. Rasa's multilingual page describes switching languages "while keeping the conversation coherent, personal, and on track", and supporting several languages "using shared Flows and logic" so you reuse one dialog structure across locales. It publishes no fixed count of supported languages, so verify your specific language against Rasa's current docs.
