Two headless cms with different operating implications. Below is the honest, agency-perspective comparison: who each fits, who each does not, and how we'd decide.
Pick Sanity if teams shipping in next.js or other js frameworks. Pick Contentful if marketing teams needing strong editor ui. The right call almost always comes down to scale, team, and where your real bottleneck is, not which tool ranks better on a generic feature comparison. We've made the call both ways across our portfolio in the same year.

|---|---|---|
| Pricing | Free up to 3 users; $99-$999+/mo at scale. | Free start + $300-$2,000+/mo at scale. |

Developer-first headless CMS.
The polished headless CMS.
Sanity fits when your bottleneck is what sanity solves well. Developer-first headless CMS. Powerful schema modeling; not the lowest-friction choice for non-technical editors. The operating reality is that teams shipping in next.js or other js frameworks, complex content models, multi-channel publishing is where it earns its keep, the rest of the feature surface tends to be a tie or close to one.
Contentful fits when your bottleneck shifts. The polished headless CMS. Editor UI is the best in the category; pricing tiers can be steep. The cases where it actually outperforms sanity cluster around marketing teams needing strong editor ui, multi-locale content. Outside of those, the choice is closer to a coin-flip, and operational fit usually decides it.
If we were scoping this for a US operator at the $5M-$30M revenue band, the call usually goes to Sanity, it covers teams shipping in next.js or other js frameworks with the least operational burden, the lowest learning curve for the in-house team, and the deepest ecosystem of agency partners who actually know it. We'd switch to Contentful the moment marketing teams needing strong editor ui becomes the binding constraint, and we've watched brands make that switch at the right time (usually) and the wrong time (occasionally). Below $5M revenue the answer is almost always whichever option lets the founder ship faster; above $50M the answer shifts toward whichever option produces the cleanest data and the strongest integration story with the rest of the stack. We've made this call both ways inside the same client portfolio in the same year, it is rarely a permanent decision and almost never the most important one the company will make this quarter.
Migration between Sanity and Contentful is a real engagement, not a weekend task. Expect to spend 2-8 weeks of calendar time depending on data depth, integration count, and team experience with the destination. The cost lives in the integration work, not the platform itself, most teams underestimate the rebuild of the analytics layer, the customer-facing flows, and the operational reporting that quietly sits behind the existing setup.
Common reasons teams leave Sanity: teams who want wysiwyg and minimal setup. Common reasons teams leave Contentful: solo founders (overkill). Sometimes the right answer is to fix the operating model rather than switch tools, we've talked operators out of migrations that wouldn't have solved what they thought they were solving.
Before a migration we audit the existing data, freeze writes during cutover, and run staging in parallel for 1-2 weeks. The post-migration period is the highest-risk window for the business, search rankings, attribution, and customer-facing flows all need to be retested under load. We have seen brands lose 6-12% of revenue or attribution during sloppy migrations. Almost always recoverable. Never costless.
