Roadmap

BubuStack is a working platform. You can deploy it today. But we're honest about the gaps — and transparent about what comes next.

Want these features sooner? Join the team. Early contributors shape the project. We use an open contributor ladder: Contributor → Reviewer → Maintainer. Ship code, get recognized, grow your role. See Get Involved.

What works today​

  • Batch workflows — DAG-based Stories with steps, conditions, parallel execution, gates, and waits.
  • Streaming workflows — Long-lived topologies with Bobravoz gRPC transport, backpressure, flow control.
  • Reusable components — Growing catalog of Engrams and Impulses with versioned templates.
  • GitOps-native — Every resource is a CRD. Deploy with Flux, Argo CD, or plain kubectl.
  • Observability — OpenTelemetry tracing, structured errors, step-level metrics.
  • Go SDK — Build Engrams and Impulses with testkit, conformance suites, and secrets management.
  • Storage offloading — S3-compatible backends for large payloads.
  • Security — RBAC, pod security defaults, cross-namespace policies, webhook validation.

Known gaps​

These are real limitations. They affect what you can build today.

GapImpactWorkaround
No feedback loops / cyclesCan't do "retry with LLM feedback until quality > 0.8". DAG-only by design.Chain executeStory with conditions
No durable executionPod dies mid-workflow, no automatic replay from checkpoint.External state store + step retries
No mutable shared stateSteps communicate only through immutable DAG edges. No shared KV store.Pass state through step outputs
No mid-execution event injectionCan't inject events into running workflows (except gate/wait primitives).Gate primitives for simple cases
No mixed batch+streamingA Story is either batch OR streaming. Not both.Separate Stories with Impulse chaining

Help us improve​

We welcome folks who will improve the ecosystem quality, docs, codebase, coverage, architecture, API design — or just share ideas and be active community members.

Concrete areas where we need help:

  • Test the platform — Deploy it, break it, open issues. Bug reports are contributions. Every issue helps us improve.
  • Improve documentation — Fix gaps, add examples, clarify confusing sections. Good docs lower the barrier for everyone.
  • Component registry and CLI — bubu-registry and the bubu CLI for scaffolding, publishing, and discovering components. Not built yet.
  • New testkit development — Improve harnesses, add assertion helpers, expand conformance suites.
  • New storage backends — GCS, Azure Blob, and beyond. The S3 interface is the current boundary.
  • New SDKs — Python SDK, TypeScript SDK. Same ABI contract as the Go SDK.
  • New transport operators — Community-contributed transport adapters beyond Bobravoz gRPC.
  • New Engrams and Impulses — Expand the catalog. Every new component makes the platform more useful.

Vision​

Where we want to take BubuStack, roughly in priority order.

Near-term​

  • Loop primitive — Bounded iteration with exit conditions. Implemented as recursive executeStory under the hood. Doesn't violate DAG model.
  • Workflow checkpointing — Durable execution semantics with automatic recovery from last checkpoint.
  • Interactive tutorial — Time-to-first-workflow under 5 minutes.
  • Expand bubu-registry — More Engrams, Impulses, and community templates.

Medium-term​

  • Native A2A protocol support — Agent-to-agent negotiation as first-class CRDs (AgentBinding, AgentTransport). MCP was donated to the Linux Foundation in December 2025 (Linux Foundation announcement) — being the first K8s-native platform with A2A/MCP CRDs is a significant differentiator.
  • MCP gateway — First-class BubuStack component for Model Context Protocol.
  • Python SDK — Same ABI contract as Go SDK.

Long-term​

  • Multi-cluster federation — Global workflows across regions.
  • Compliance primitives — Audit trail CRDs, cost attribution, EU AI Act traceability.
  • Mixed batch+streaming Stories — Single Story with both patterns.

How to pick up work​

  1. Browse open issues tagged good first issue or help wanted.
  2. Comment on a roadmap item in GitHub Discussions to coordinate.
  3. For large features, open a design discussion before writing code.
  4. See Get Involved for contribution guidelines and the contributor ladder.
