Svix

Here is the Svix changelog for May! 📚 New docs website We gave the docs website a facelift with better search, navigation, and overall experience, plus a dedicated docs page for message tags. 🚫 Listing attempts shows canceled messages as canceled Attempts canceled due to transformations now correctly display as canceled in the UI instead of "Successful". The API still returns "Successful" for backwards compatibility, with a new version in the works. 🛡️ FIPS-140-3 compliant Enterprise Edition image The Svix Enterprise Edition image is now available in a FIPS-140-3 compliant configuration, so customers with strict cryptographic compliance requirements can run Svix on-premise while meeting their FIPS obligations. 🖥️ App portal Replay button redesign The Replay control in the app portal is now easier to discover, with a clearly labeled "Replay" text button and separate buttons for endpoint actions instead of a hidden ellipsis menu. 🛠️ Ingest improvements We've shipped a batch of Ingest fixes and improvements based on user feedback, including a fix for tab switching in the app portal, plus better activity visibility for FIFO endpoints and new ingest types.

Here is the Svix changelog for April! Thread 🧵 💎 Diom: the Components Platform We are very excited to announce the release of Diom, a backend components platform for building robust services. It runs in your own infrastructure and provides primitives like cache, rate-limiting, idempotency, and queues out of the box. 📊 Application analytics The application screen in the dashboard now offers richer analytics. You can filter by flexible date ranges, break down attempts by event type, and see succeeded vs. failed counts. 🔑 OAuth 2.0 token endpoint custom headers You can now pass custom headers to the OAuth token endpoint when Svix fetches access tokens on your behalf, in addition to existing support for custom body parameters. 🛡️ Server CA certificate override The CA certificate override for outbound webhooks is now decoupled from mTLS configuration. You can override the server CA on a per-endpoint basis without also setting up mutual TLS. 🖥️ App portal: endpoint secret visibility control The "View endpoint secret" button in the app portal is now correctly disabled when capabilities don't permit it. Previously the button appeared enabled even when the capability was restricted.

Here is the Svix changelog for February! 🔄 Bulk replay successful messages Svix now supports bulk replay which lets you bulk replay all messages sent to an endpoint based on some common filters such as time, event type, status, and channel. This makes it easy for your customers to bulk redrive messages that they have already previously processed successfully. 📧 App portal: support multiple email addresses for notifications The app portal now supports configuring multiple email addresses for notifications. This makes it easier to keep your entire team informed about important webhook events and system updates without having to rely on a single point of contact or a common mailing address. 🌑 App portal: support automatic dark mode detection Until this change, dark mode was an explicit setting you would need to toggle for a customer based on their dark mode preferences. This works well if the preferences are set explicitly in your application, but required a bit of additional work for applications where dark mode is detected automatically from the system preferences. That why we we've now added a new darkMode=auto option to set dark mode automatically based on your customer environment; so if your app does auto-detection, the app portal can do so as well. 🏎️ Improve performance of list attempted messages when there are no recent messages We've optimized the performance of listing attempted messages, particularly in cases where there are no recent messages but there are a lot of historical ones. This results in faster load times and a more responsive experience when viewing message history. 🖥 Play: highlighting more features in the play UI We've enhanced the Play UI to better showcase its more advanced features. For example, Svix Play has an API that lets you configure things like response status code (including at random), and automatically verifying endpoint signatures. Link to full posts in comments!

Svix is now available in the Okta Integration Network! Svix has always supported SSO with Okta, but it's now a verified integration on OIN and it also makes the integration much nicer. https://lnkd.in/dQ4KPHE5

Here is the January Svix changelog! In addition, we would love to hear: what should Svix build, fix, or improve in 2026? As for the changelog: 🧵 🕑 Background tasks: show progress in the app portal While it was always possible to track the progress of background tasks using the API, this information wasn't easily accessible for users of the app portal. With this change, the app portal now shows running tasks with their progress, displaying messages like "Replaying failed messages from A to B (45% complete)". 👥 Organization group user listing - MFA status We've added MFA (Multi-Factor Authentication) status visibility to the organization group user listing. This makes it easier for administrators to see at a glance which users in their organization have enabled MFA for enhanced security. 🖥 OpenAPI spec import improvements We've significantly improved how we handle OpenAPI spec imports. Previously, we flattened JSON schemas for simplicity, but this approach was problematic with deeply nested schemas and broke entirely with reference loops. We now changed it to traverse the import tree intelligently, keeping only what's needed and pruning everything else. This results in cleaner imports that handle complex schemas and circular references gracefully. Link in comments!
