Why Contentful Customers Are Quietly Exploring Contentstack Right Now

On June 1, 2026, Salesforce announced a definitive agreement to acquire Contentful. The deal is expected to close by the end of October 2026.

If you are a Contentful customer, you probably saw the news and had one of two reactions. Either "this is great, we already use Salesforce" or "wait, we picked Contentful specifically because it was independent."

That second group is the one worth paying attention to right now. Because in the three weeks since the announcement, something interesting has been happening. Contentstack launched a dedicated migration offer for Contentful customers. Competitors like Cosmic and Sanity published open letters. And a lot of teams that were perfectly happy with their CMS three months ago are now quietly running vendor evaluations they did not expect to be running in 2026.

This article is not a hit piece on Contentful or Salesforce. The acquisition makes strategic sense for both companies. But if you are a Contentful customer who chose headless architecture to avoid platform lock-in, the questions you should be asking right now are real and time-sensitive.

What Salesforce Actually Said

Salesforce framed the acquisition around three things: Data 360, Agentforce, and Contentful's composable APIs working together to deliver personalized experiences at scale. The pitch is that Contentful becomes the native content layer inside Customer 360, and Agentforce (Salesforce's AI agent platform) gets the ability to query, assemble, and deliver content dynamically.

That is a compelling vision if you are a Salesforce shop. Your CRM data, your content, and your AI agents all living in the same ecosystem with native integrations.

But here is the part that matters for everyone else. Salesforce explicitly described Contentful as a content layer for Agentforce, not as a standalone best-of-breed CMS. That distinction is not just marketing language. It tells you where the product roadmap priorities are heading.

If you are an Agentforce customer, this is probably good news. If you are not, and you have no plans to be, then the product you are paying for is about to start optimizing for an audience that is not you.

What Usually Happens After These Acquisitions

Every acquisition is different, and Salesforce may handle this one well. But there are patterns that tend to repeat when a focused developer tool gets absorbed into a large enterprise platform.

Pricing structures change. Standalone pricing gets replaced by bundle logic. Your CMS license stops being an independent purchasing decision and becomes a line item inside a Salesforce enterprise agreement. The leverage in that negotiation shifts, and it does not shift toward the buyer.

Product roadmaps realign. Features that serve the parent company's strategic goals (in this case, Agentforce and Customer 360 integration) get prioritized. Features that serve standalone customers tend to slow down. Not because anyone decides to kill them, but because resources flow toward the thing the parent company is measuring.

Support and account structures reorganize. The people you know may move. Response times may change during the integration period. This is not speculation. This is what happens in most enterprise software acquisitions during the 12 to 24 months after close.

And then there is the European angle. Contentful was incorporated as Contentful GmbH in Berlin. Once the deal closes, it falls under US law, including CLOUD Act jurisdiction. Dries Buytaert, the founder of Drupal, pointed this out publicly. For organizations that chose Contentful partly for its European footing, this is worth raising with legal and compliance teams before the next renewal.

What Contentstack Is Offering

Contentstack moved fast. Within days of the announcement, they launched what they are calling the Contentful Migration Pledge. It is a structured offer for Contentful customers who want to migrate before the deal closes. The details:

A first-year price match guarantee for any Premium Contentful subscriber. Payment terms deferred for the first 90 days. A dedicated migration architect, pre-built Contentful migration schemas, and 90 days of post-launch support after go-live. The deadline is October 31, 2026.

Contentstack is also positioning their existing product as the thing Salesforce is promising to build. Their argument is straightforward. They already have Content Cloud, Data Cloud, and Agent OS live and available. Salesforce will not start its multi-quarter integration process until after the deal closes in late October. So if you want the "content plus data plus AI agent" stack today, Contentstack says it already exists without being tied to a CRM vendor.

That positioning is obviously self-serving. Contentstack is a direct competitor and they stand to benefit from every customer that leaves Contentful. But the offer itself is concrete and time-bound, which is more than most vendor pitches.

The Migration Is the Hard Part

Here is the thing nobody in the marketing copy talks about. Switching headless CMS platforms is not a weekend project. Content models do not map one to one between systems. Field types behave differently. Reference relationships break. Rich text rendering varies. Localization is handled completely differently depending on the platform.

We wrote about this exact problem when we covered what happens to your content structure when you switch CMS platforms. The data moves. The structure is what breaks.

And if you have never done a proper inventory of what is actually on your site, you are going to hit surprises during migration that could have been caught in week one. We documented this in detail when we wrote about what a CMS audit actually reveals before you migrate a single page. Teams regularly discover three to four times more content types than they thought they had.

Contentstack does have an open-source Migration Framework that supports Contentful as a source. It handles content type mapping, field mapping, locale mapping, and test migrations through a step-by-step interface. It is a real tool, not a marketing page. But a migration framework handles the mechanical part of moving data. It does not handle the content architecture decisions that determine whether the migration actually works in production.

That is the gap where most migrations fall apart. Not the tooling. The decisions that happen before the tooling runs.

What You Should Do in the Next 30 Days

If you are a Contentful customer, regardless of whether you plan to stay or leave, there are a few things worth doing now while you still have leverage.

Get your contract terms confirmed in writing. Specifically: is your current price locked, for how long, and what happens at renewal if Contentful is now a Salesforce entity.

Ask for the product roadmap in writing. Not a slide deck. Not a verbal assurance. A written commitment about what the next 12 months of development look like for standalone Contentful customers who are not on Salesforce.

Run a content audit. Know what you actually have. Content types, field structures, reference relationships, localization architecture. If you do decide to move, that audit is the single most important input to the migration plan. If you decide to stay, it is still useful for every other operational reason.

Understand your data residency obligations. If you are in a regulated industry or operating under European data protection frameworks, the jurisdictional change from a German company to a US corporation is worth reviewing with your compliance team.

Evaluate alternatives with clear criteria. Contentstack is the loudest option right now because of the Migration Pledge. But Sanity, Cosmic, Hygraph, and Payload are all legitimate alternatives depending on your technical requirements and team size. The right platform is the one that matches your content architecture, your governance model, and your integration needs, not the one with the best migration marketing.

Where Smuves Fits

We are a Contentstack Preferred Partner, and we have done large-scale content migrations involving tens of thousands of entries, dozens of content types, and multiple languages. We know what breaks during these projects because we have fixed it in production.

If your team is evaluating a move from Contentful to Contentstack and wants to get the structural piece right before the tooling runs, that is exactly the kind of work we do. Content audits, content model mapping, transformation rule design, and the bulk editing and QA work that follows a migration.

The October 31 deadline on Contentstack's Migration Pledge is real. If you are serious about evaluating a move, the window to start the conversation is now, not in September when everyone else is scrambling.
