1. Interoperability and Federation

• Dual Protocol Support: Wafrn connects simultaneously with both the Fediverse (using the ActivityPub protocol) and Bluesky (using the ATProtocol),.

• Native Bluesky Integration: Unlike much of the Fediverse, Wafrn offers native Bluesky Integration,. This means that Bluesky users do not need to opt-in to a bridge to interact with Wafrn users.

• Seamless Interaction: The native integration allows for the smooth flow of replies, likes, and boosts between Wafrn and Bluesky users,. Posts can be made visible on both Bluesky and Mastodon.

• User and Data Portability: Users can keep all their data (posts, followers, likes, lists) when moving between ATProtocol-based sites (like Blacksky or Northsky),. If a user migrates from Bluesky to Wafrn, their posts, friends, and followers are preserved. This portability is cited as a way to escape "enshittification".

2. User Experience and Customization

• Theming and Custom CSS: Wafrn is highly focused on customization, allowing users to apply custom CSS to their profile, which then sets the default theme across their entire site view,. The default interface often resembles the Tumblr dashboard,.

• Feeds: The platform offers three main feeds: the Dashboard (focused on followed accounts), Explore Wafrn (local Wafrn accounts), and Wafrn & Friends (combining local content with posts from other federated servers like Mastodon, Friendica, and Bluesky),.

• Custom Feeds (Future): There is expressed interest in supporting Bluesky’s Custom Feeds for better discovery,.

3. Posting, Content, and Format

• Rich Formatting: Posts support a mix of Markdown (including CommonMark) and various HTML tags for formatting.

• Inline Media: Users can embed media directly within the text of their posts using a specific markup (![media-{number}]).

• Accessibility and Media: The platform takes accessibility seriously, requiring descriptions for images or videos (alt text). Posts are limited to displaying four pieces of media for Mastodon and Bluesky users.

• "Tumblr-isms": Includes unique, playful features that capture a chaotic energy,:

  • Asks: A Question-and-Answer feature where any Fediverse account can submit questions, which appear in a special tab for the user to answer.

  • Bites: A "silly feature" resembling a poke that generates cute notifications,.

  • AI Filter: Allows users to transform the word “AI” to “cocaine” or another word using a custom filter,.

4. Privacy, Security, and Ethos

• Anti-AI Policy: Wafrn does not sell data for AI training, nor does it accept contributions involving AI generated artwork, code or text,,.

• Post Privacy Options: Supports several levels of visibility: Public, Unlisted, This Instance Only, Followers-Only, and Direct Message (which is explicitly stated as not End-To-End-Encrypted).

• Public Content Risk: The platform warns that public posts on Wafrn, especially those sent to Bluesky, cannot be prevented from being scraped by AI companies or others,.

• Open Source Commitment: The code is public under the AGPLv3 (backend) and Apache License 2.0 (frontend),.

5. Technical and Miscellaneous

Here are the principal functionalities and features of Chi:

1. Core Design and Philosophy

• Lightweight and Idiomatic: Chi is characterized by its lightweight nature and its adherence to the standard net/http interfaces, making it highly idiomatic to the Go language,,.

• Composability: It simplifies the construction of large REST API services by enabling the system to be broken down into smaller, manageable components.

• Performance: Chi generally offers better performance than Gorilla Mux and consumes less memory. Compared to Gin, Chi typically uses fewer allocations while maintaining exceptional performance under high load.

• Installation: It is installed as a dependency using the Go module system via the command go get -u github.com/go-chi/chi/v5,.

2. Routing Capabilities

• Standard HTTP Methods: Chi supports routing for all standard HTTP methods, including GET, POST, HEAD, PUT, PATCH, DELETE, OPTIONS, TRACE, and CONNECT.

• Radix Tree Structure: The router is built on an efficient radix tree structure for quick and flexible routing,.

• URL Parameter Handling: It simplifies the extraction of input parameters, whether they come from the URL, the request body, or query parameters. Specific parameters, such as a requested book ID, are easily read from the URL using the chi.URLParam function.

• Sub-routers and Grouping: Chi allows for the creation of sub-routers using the r.Mount method, which helps organize and link related routes (e.g., all book routes linked to /books),,. Related routes can also be organized using r.Group.

• Advanced Pattern Matching: It supports sophisticated URL pattern matching, including regex constraints (e.g., /{id:+}) and wildcard patterns (e.g., /files/{filename:.+}).

3. Middleware System

• Flexible and Focused Design: Chi's design places its middleware system at the forefront, allowing developers to easily compose and maintain their middleware stack with minimal boilerplate,.

• Compatibility: Its middleware handlers are standard stdlib net/http handlers, ensuring compatibility with any middleware available in the Go community,.

• Usage: Middleware defines pre-handler and post-handler stages for implementing cross-cutting concerns like authentication, logging, tracing, and general request processing,. Middleware can be applied globally (r.Use) or scoped to specific handlers or groups (r.Group or r.With).

4. Context Management

• Request-Scoped Data: Chi brilliantly leverages Go’s built-in context package to manage requests. Contexts act as carriers for important, request-scoped data, such as user IDs or request metadata, seamlessly passing information through the middleware chain to the handler,,.

• Timeouts and Cancellation: Context is used for managing crucial elements like request timeouts to ensure the application remains responsive. Developers are advised to always call the cancel function when using contexts with timeouts or deadlines to prevent resource leaks.

5. Testing and Error Handling

• Simplified Error Handling: Error handling is simple, relying on the standard http package's Error() function to respond with a specific error message and HTTP status code constant (e.g., http.StatusNotFound),.

• Unit Testing: Chi encourages unit testing by allowing the handler functions to use an interface for storage access (e.g., BookStorage), which makes it easy to substitute real storage with mock (fake) storage during tests,,. The httptest package can be used to construct the necessary http.ResponseWriter and http.Request parameters for isolated handler tests.

• Integration Testing: Integration tests can be performed by starting a test server using the httptest.NewServer function, allowing tests to make actual HTTP requests against the defined router without mocking components,.

p2panda offers building blocks for peer-to-peer applications. Its primary aim is to provide everything necessary to create modern, privacy-respecting and secure local-first applications.

Here is a summary of p2panda's main features and functionalities:

Core Architecture and Design Philosophy

• Modular Approach: p2panda adopts a modular approach using various Rust crates, allowing projects the freedom to select specific components they need and integrate them with minimal friction. This design contributes to a wider, interoperable p2p ecosystem.

• Data Compatibility: Many Rust crates operate over raw bytes and are fully compatible with your own data types and any CRDT (Conflict-free Replicated Data Type).

• Offline-First Guarantee: The project is founded on a radical offline-first guarantee. Collaboration, encryption, and access-control must function even when operating over unstable or ephemeral connections.

• Post-Internet Communication: The protocol is "broadcast-only" at its heart, making the data compatible with post-internet communication infrastructure such as shortwave, packet radio, Bluetooth Low Energy (BLE), LoRa, or even a USB stick.

• Standard Integration: p2panda utilizes existing libraries and well-established standards like iroh, BLAKE3, Ed25519, STUN, CBOR, TLS, QUIC, and Double Ratchet.

Specific Library Features (Crates)

p2panda provides several specialized libraries for building P2P applications:

Library NameFunctionalityp2panda-netFinds peers, connects to them directly, and exchanges data in byte streams.p2panda-discoveryProvides solutions to find other peers in the local network or on the internet.p2panda-syncImplements protocols to efficiently "catch up on past state" with other peers.p2panda-blobsEnables efficient sending, receiving, and storage of (very large) files.p2panda-coreManages the highly extensible data-types required for the secure, distributed, and efficient exchange of data.p2panda-storeOffers interfaces to store p2panda data types in databases, memory, or file-systems.p2panda-streamProvides methods to process p2panda data streams before they reach the application.p2panda-encryptionSupports decentralized secure data- and message encryption for groups, featuring post-compromise security and optional forward secrecy.p2panda-authFacilitates decentralised group management with fine-grained, per-member permissions.p2panda-node (WIP)Acts as an all-in-one p2panda node usable in federated or fully decentralised networks, supporting "lightweight" clients running in the browser.

Collaborative Projects and Research

p2panda is also a multifaceted project involved in organizing community events, research, and application development. Related application projects demonstrate the capabilities of the tool:

• Reflection (coming mid-2025): A local-first, collaborative text editor.

• Toolkitty (coming mid-2025): An autonomous coordination toolkit for collectives, built for iOS, Android, and Desktop.

• Meli Bees App: A collaborative Android app for sighting and categorization of bee species.

• rhio: A peer-to-peer message router and file sync solution that allows processes to rapidly exchange messages and efficiently replicate large files without central coordination.

Analogy: p2panda acts like an advanced LEGO set for building secure, digital neighborhoods. Instead of relying on a central city infrastructure (the internet backbone), each block (crate) lets you build essential features—like finding neighbors (p2panda-discovery), securely whispering secrets (p2panda-encryption), or trading large goods (p2panda-blobs)—all while ensuring your neighborhood can still function perfectly even if the main power lines go down (radical offline-first guarantee).
