If your users don’t trust how you handle data, especially when integrating with third-party tools, it can derail deals and erode trust. Unified APIs have changed the game by letting you launch integrations faster. But under the hood, not all unified APIs work the same way — and **Kombo.dev and Knit.dev take very different approaches**, especially when it comes to **data sync**, **compliance**, and **scalability**. Let’s break it down. What is a Unified API? ---------------------- Unified APIs let you integrate once and connect with many applications (like HR tools, CRMs, or payroll systems). They normalize different APIs into one schema so you don’t have to build from scratch for every tool. A typical unified API has 4 core components: - **Authentication & Authorization** - **Connectors** - **Data Sync (initial + delta)** - **Integration Management** Data Sync Architecture: Kombo vs Knit ------------------------------------- ### Between the Source App and Unified API - **Kombo.dev** uses a **copy-and-store model**. Once a user connects an app, Kombo: ‍ - Pulls the data from the source app. - Stores a copy of that data on their servers. - Uses polling or webhooks to keep the copy updated. ‍ - **Knit.dev** is different: **it doesn’t store any customer data. ‍** - Once a user connects an app, Knit: - Delivers both initial and delta syncs via **event-driven webhooks**. - Pushes data directly to your app without persisting it anywhere. ### Between the Unified API and Your App - **Kombo** uses a **pull model** — you’re expected to call their API to fetch updates. ‍ - **Knit** uses a **pure push model** — data is sent to your registered webhook in real-time. Why This Matters ---------------- FactorKombo.devKnit.devData PrivacyStores customer dataDoes not store customer dataLatency & PerformancePolling introduces sync delaysReal-time webhooks for instant updatesEngineering EffortRequires polling infrastructure on your endFully push-based, no polling infra needed ‍ Authentication & Authorization ---------------------------------- - **Kombo** offers pre-built UI components. - **Knit** provides a **flexible JS SDK** + **Magic Link flow** for seamless auth customization. This makes Knit ideal if you care about branding and custom UX. ‍ Summary Table ------------- FeatureKombo.devKnit.devData SyncStore-and-pullPush-only webhooksData StorageYesNoDelta SyncsPolling or webhook to KomboWebhooks to your appAuth FlowUI widgetsSDK + Magic LinkMonitoringBasicAdvanced (RCA, reruns, logs)Real-Time Use CasesLimitedFully supported ‍ Tom summarize, Knit API is the only unified API that does not store customer data at our end, and offers a scalable, secure, event-driven push data sync architecture for smaller as well as larger data loads.By now, if you are convinced that Knit API is worth giving a try, please c[lick here t](/book-demo)o get your API keys.
