Marketplace overview

:::caution 0.2.0 Private Preview snapshot

This independent snapshot records what was true for 0.2.0. The legacy marketplace pages were illustrative in that release: no public marketplace, supported third-party SDK distribution, live publish path, revenue program, review SLA, analytics/ranking contract, or marketplace legal agreement was available.

:::

In 0.2.0, extension compatibility belonged to the pinned release bundle:

• The 0.2.0 step contract did not provide the later Describe handshake, authoritative phase discovery, or contract-version enforcement. Use only artifacts pinned in the installed bundle.
• The repository contained WASM plugin and CLI-development code, but no supported 0.2.0 production path loaded arbitrary marketplace artifacts.
• nexoctl scaffold, validate, and test were development aids. publish was suitable only for a clean-directory dry run; no live marketplace upload was supported.
• Dashboard marketplace cards, prices, downloads, sorting, install buttons, and API calls were UI/seed concepts, not a live catalog.

Documentation map

• Developer guide — lifecycle, manifests, hooks, workflow, security, and current CLI boundaries.
• Plugin SDK and contract reference — current step contract, repository-local WASM SDK shape, and the complete legacy SDK snippets.
• Publishing and policy — manifest fields, versioning, review, commercial, analytics, delisting, and legal claims, all explicitly qualified.
• Examples — three complete legacy examples, the repository-local rate limiter, catalog seed cards, and idea lists.

Conceptual lifecycle

The retired docs described client request → request plugins → MongoDB → response plugins → client response, with optional router and connection hooks. In 0.2.0 these marketplace hooks were not a supported deployment contract, and the later Describe/authoritative-phase model did not exist. Runtime behavior had to be verified against the exact pinned bundle.

The dashboard presents search, category filtering, “popular/newest/price” sorting, “Publish a Plugin,” and “Install” controls. They must be read as interface prototypes. Download counts, prices, tiers, rankings, availability, and installability are not supported facts.

Legacy/illustrative plugin ideas

• Datadog Logger — query logs with APM correlation (legacy demand: High).
• Slack Alerter — alerts for slow queries, errors, and schema violations (High).
• GraphQL-to-Mongo — translate GraphQL to find/aggregate (Medium).
• IP Allowlisting — IP and geo-fencing (High).
• Query Analyzer — explain-plan suggestions in response metadata (Medium).
• RBAC Enforcer — collection/field permissions from JWT claims (High).
• Change Feed to Kafka — stream change events to Kafka (High).
• Auto-Archiver — move old documents to cold collections (Medium).

These are idea prompts, not available products or validated market-demand measurements.
