In July 2025, Grafbase delivered a set of architectural, extensibility, and reliability improvements across grafbase/grafbase, focusing on business value, security, and developer productivity. Key refactors unified federated-server components (graph, engine, router) and merged engine-axum for a single module boundary, paving the way for scalable multi-tenant federation. The extensions model was upgraded by separating gateway and engine responsibilities, moving away from hooks/all to a clearer, extensible structure. Foundational work on contracts and SDK extended the engine with core contract handling, host-side contracts, and a ContractsExtension, complemented by SDK cleanup and version consolidation and new documentation. Authentication was relocated to the Axum layer to protect the /mcp route, tightening security without impacting client workflows. WASM context and error handling were reworked to improve reliability, with improved per-name state sharing. Additional progress included CLI/MCP improvements (forwarding headers by default, introspected schema visibility in logs) and routine releases (CLI 0.99.4/0.99.5/0.99.7) along with telemetry path configuration, and broader CI/dependency maintenance to stabilize the pipeline and mitigate risk on upcoming features.

April 2025 highlights across Grafbase focused on end-to-end feature delivery, runtime reliability, and developer ergonomics. Key work included an end-to-end Selection Set Resolver wired across SDK and WASM (extension, subgraph schema delivery, and tests), root schema types with an improved field.selection_set API, and initial support for composite directives. Engine and gateway improvements substantially increased reliability and flexibility, including ingestion of @lookup directives, initial @lookup support, @oneOf support, and advanced composite batch key/lookup matching, along with significant error-handling improvements and fixes for infinite debug loops and resolvable: false handling. Gateway gained CBOR content-type support and environment variable expansion across all configuration, while MCP tooling was modernized with a new search tool and migration to a separate crate. Additional boosts came from CLI enhancements (MCP command, auto-install extensions), test-infra renames reflecting gateway terminology, and a Cargo.lock refresh. Overall impact: faster, more reliable data resolution and schema expressivity, enabling quicker feature delivery and better business outcomes for customers.

January 2025 monthly summary focused on delivering a scalable foundation for Grafbase extensibility and fortified reliability for real-world deployments. Key work included delivering the Grafbase Extension System and Federated Graphs, enabling modular extensions, extension directives, manifests, and a federated graph catalog. This set the stage for multi-subgraph architectures and ecosystem extensions, with initial test extensions and basic integration tests validating the end-to-end flow. Security and reliability improvements were a priority, including WebSocket header propagation with hardened policies to improve protocol adherence and policy compliance in real-time channels. On the reliability and correctness side, we tightened Automatic Persisted Queries (APQ) handling and response deserialization, corrected missing query scenarios, and improved subgraph response handling. Engine deserialization was hardened to use proper search strategies for field keys and to merge default objects correctly when subgraph requests fail. A targeted GraphQL schema cleanup reduced drift by removing unused scalar/field definitions. Release management was completed with updates to version numbers and changelogs for release 0.28.1 to improve customer visibility and onboarding. Overall impact: increased developer productivity through extensibility, improved reliability for query planning and subgraph orchestration, and clearer customer-facing communication of changes. Technologies/skills demonstrated: GraphQL, Grafbase extension architecture, federated graphs, integration testing, APQ, WebSocket security, schema maintenance, release tooling and changelog discipline.
