  • This requires manually enabling every additional provider. This doesn’t work if some individuals or smaller collectives wanna run their own identity providers, numbering in the thousands.

  • Forgejo has a feature (that people usually disable) where you can bring your own openid connect url and use it to auth. So if I have my own OIDC provider I am self hosting, I can just use that to log in.

    Most people only use OIDC for google and microsoft and whatnot but it's very possible. I don't realkly see what FedCM offers that OIDC doesn't or can't, or why we shouldn't be adding features to the existing and popular OIDC instead.

  • You might be confusing the old OpenID with OIDC (short for Open ID Connect), which is based on Oauth2, an entirely different technology.

    OpenID was definitely more decentralized compared to how OIDC is commonly used these days, but OIDC has various little know options to do similar things.

  • See what CIMD solves for. “Innately centralized” was probably a poor choice of words, but OIDC not a good fit for an open social web with decentralized identities and a plethora of small identity providers that cannot be known upfront.

  • OIDC is innately centralized

    Huh, that's not my understanding. I was there when it first came out, and the whole point was to allow you to use any URI of your choice as an authenticator. Let's see what the first line of Wikipedia has to say:

    OpenID is an open standard and decentralized authentication protocol

    Huh. 🤔

  • OIDC isn't "innately centralized", thats just how the majority of people use it. And the same will be likely true for FedCM.

    Fedify 1.10.0: Observability foundations for the future debug dashboard Fedify is a #TypeScript framework for building #ActivityPub servers that participate in the #fediverse. It reduces the complexity and boilerplate typically required for ActivityPub implementation while providing comprehensive federation capabilities. We're excited to announce #Fedify 1.10.0, a focused release that lays critical groundwork for future debugging and observability features. Released on December 24, 2025, this version introduces infrastructure improvements that will enable the upcoming debug dashboard while maintaining full backward compatibility with existing Fedify applications. This release represents a transitional step toward Fedify 2.0.0, introducing optional capabilities that will become standard in the next major version. The changes focus on enabling richer observability through OpenTelemetry enhancements and adding prefix scanning capabilities to the key–value store interface. Enhanced OpenTelemetry instrumentation Fedify 1.10.0 significantly expands OpenTelemetry instrumentation with span events that capture detailed ActivityPub data. These enhancements enable richer observability and debugging capabilities without relying solely on span attributes, which are limited to primitive values. The new span events provide complete activity payloads and verification status, making it possible to build comprehensive debugging tools that show the full context of federation operations: activitypub.activity.received event on activitypub.inbox span — records the full activity JSON, verification status (activity verified, HTTP signatures verified, Linked Data signatures verified), and actor information activitypub.activity.sent event on activitypub.send_activity span — records the full activity JSON and target inbox URL activitypub.object.fetched event on activitypub.lookup_object span — records the fetched object's type and complete JSON-LD representation Additionally, Fedify now instruments previously uncovered operations: activitypub.fetch_document span for document loader operations, tracking URL fetching, HTTP redirects, and final document URLs activitypub.verify_key_ownership span for cryptographic key ownership verification, recording actor ID, key ID, verification result, and the verification method used These instrumentation improvements emerged from work on issue #234 (Real-time ActivityPub debug dashboard). Rather than introducing a custom observer interface as originally proposed in #323, we leveraged Fedify's existing OpenTelemetry infrastructure to capture rich federation data through span events. This approach provides a standards-based foundation that's composable with existing observability tools like Jaeger, Zipkin, and Grafana Tempo. Distributed trace storage with FedifySpanExporter Building on the enhanced instrumentation, Fedify 1.10.0 introduces FedifySpanExporter, a new OpenTelemetry SpanExporter that persists ActivityPub activity traces to a KvStore. This enables distributed tracing support across multiple nodes in a Fedify deployment, which is essential for building debug dashboards that can show complete request flows across web servers and background workers. The new @fedify/fedify/otel module provides the following types and interfaces: import { MemoryKvStore } from "@fedify/fedify"; import { FedifySpanExporter } from "@fedify/fedify/otel"; import { BasicTracerProvider, SimpleSpanProcessor, } from "@opentelemetry/sdk-trace-base"; const kv = new MemoryKvStore(); const exporter = new FedifySpanExporter(kv, { ttl: Temporal.Duration.from({ hours: 1 }), }); const provider = new BasicTracerProvider(); provider.addSpanProcessor(new SimpleSpanProcessor(exporter)); The stored traces can be queried for display in debugging interfaces: // Get all activities for a specific trace const activities = await exporter.getActivitiesByTraceId(traceId); // Get recent traces with summary information const recentTraces = await exporter.getRecentTraces({ limit: 100 }); The exporter supports two storage strategies depending on the KvStore capabilities. When the list() method is available (preferred), it stores individual records with keys like [prefix, traceId, spanId]. When only cas() is available, it uses compare-and-swap operations to append records to arrays stored per trace. This infrastructure provides the foundation for implementing a comprehensive debug dashboard as a custom SpanExporter, as outlined in the updated implementation plan for issue #234. Optional list() method for KvStore interface Fedify 1.10.0 adds an optional list() method to the KvStore interface for enumerating entries by key prefix. This method enables efficient prefix scanning, which is useful for implementing features like distributed trace storage, cache invalidation by prefix, and listing related entries. interface KvStore { // ... existing methods list?(prefix?: KvKey): AsyncIterable<KvStoreListEntry>; } When the prefix parameter is omitted or empty, list() returns all entries in the store. This is useful for debugging and administrative purposes. All official KvStore implementations have been updated to support this method: MemoryKvStore — filters in-memory keys by prefix SqliteKvStore — uses LIKE query with JSON key pattern PostgresKvStore — uses array slice comparison RedisKvStore — uses SCAN with pattern matching and key deserialization DenoKvStore — delegates to Deno KV's built-in list() API WorkersKvStore — uses Cloudflare Workers KV list() with JSON key prefix pattern While list() is currently optional to give existing custom KvStore implementations time to add support, it will become a required method in Fedify 2.0.0 (tracked in issue #499). This migration path allows implementers to gradually adopt the new capability throughout the 1.x release cycle. The addition of list() support was implemented in pull request #500, which also included the setup of proper testing infrastructure for WorkersKvStore using Vitest with @cloudflare/vitest-pool-workers. NestJS 11 and Express 5 support Thanks to a contribution from Cho Hasang (@crohasang@hackers.pub), the @fedify/nestjs package now supports NestJS 11 environments that use Express 5. The peer dependency range for Express has been widened to ^4.0.0 || ^5.0.0, eliminating peer dependency conflicts in modern NestJS projects while maintaining backward compatibility with Express 4. This change, implemented in pull request #493, keeps the workspace catalog pinned to Express 4 for internal development and test stability while allowing Express 5 in consuming applications. What's next Fedify 1.10.0 serves as a stepping stone toward the upcoming 2.0.0 release. The optional list() method introduced in this version will become required in 2.0.0, simplifying the interface contract and allowing Fedify internals to rely on prefix scanning being universally available. The enhanced #OpenTelemetry instrumentation and FedifySpanExporter provide the foundation for implementing the debug dashboard proposed in issue #234. The next steps include building the web dashboard UI with real-time activity lists, filtering, and JSON inspection capabilities—all as a separate package that leverages the standards-based observability infrastructure introduced in this release. Depending on the development timeline and feature priorities, there may be additional 1.x releases before the 2.0.0 migration. For developers building custom KvStore implementations, now is the time to add list() support to prepare for the eventual 2.0.0 upgrade. The implementation patterns used in the official backends provide clear guidance for various storage strategies. Acknowledgments Special thanks to Cho Hasang (@crohasang@hackers.pub) for the NestJS 11 compatibility improvements, and to all community members who provided feedback and testing for the new observability features.

    Vacations are wonderful. It is a privilege to be able to travel without worry. It's also wonderful to be home, and to have the time to work on projects I care about. With those thoughts in mind, I present release v3.1.1 of Ktistec, an ActivityPub server written in the Crystal programming language!This release is a mixed bag of small features and improvements:AddedAuto-link URLs in posts. (fixes #24)Support searching by actor username. (fixes #102)Support hourly granularity in metrics charts.FixedMark actor as down if refresh fails.Remove draft posts from the everything collection.Ignore charts with no points in the date range.Ensure HTTP::Client instances are closed.I added support for multiple users at the beginning of the month. I'm very interested in feedback on how that's working out for anyone using it.#ktistec #fediverse #activitypub #crystallang
