Why teams connect Anthropic and Supabase

Sync the records in Supabase into Anthropic and land its embeddings, classifications, and generated fields back on the same rows, in real time and without a pipeline to maintain.

Anthropic is a read-only source: Stacksync reads its data in real time and delivers it into Supabase, so Supabase always reflects the current state of Anthropic — without exports, scripts, or schedulers.

AI systems do not hold customers or invoices the way business apps do. What they hold is derived from your data: the vectors and metadata in a vector store, or the classifications, extracted fields, and generated text a model produces over records it was given. Supabase is where those source records actually live. The bridge between the two is the row itself, since an item in Anthropic and the record in Supabase it describes are two halves of the same thing, and they drift the moment one is updated without the other.

Stacksync syncs Views, Schemas, auth.users, Row Level Security Policies in Supabase with Message Batches, Models, Usage Report (messages), Cost Report in Anthropic in real time. Rows created or changed in Supabase flow into Anthropic so inference and embedding run on current data, and the scores, labels, and generated fields Anthropic produces flow back onto the matching rows in Supabase, mapped field by field. A change on either side appears on the other within seconds, with no extraction job or webhook plumbing to keep alive.

Because matching is by a stable identifier, every row in Supabase stays tied to its AI-side counterpart in Anthropic. Retrieval, enrichment, and generated content always resolve back to the record they came from, so there are no orphaned vectors and no labels describing a version of a row that no longer exists.

Common use cases

  • 01 Pull the Usage Report into a warehouse to attribute Claude token spend by workspace, model, and API key for internal chargeback.
  • 02 Sync the Cost Report into a finance database or FinOps tool for daily AI-spend reporting alongside other vendor costs.
  • 03 Reflect auth.users state into support and CRM systems so teams see account status without querying the database
  • 04 Push product events captured in Supabase Postgres to marketing tools for lifecycle campaigns

Common sync patterns

Write results back onto the record

Scores, labels, extracted fields, or generated text produced in Anthropic land on the matching row in Supabase, next to the source data your applications already query.

Keep derived data fresh as sources change

When a row in Supabase is updated or removed, its counterpart in Anthropic is updated or removed too, so nothing in Anthropic describes a record that has since changed or gone.

Backfill once, then stay in step

Load your existing rows from Supabase into Anthropic to build the index or enrichment set, then let ongoing changes sync automatically instead of re-running the whole job.

What you can sync between Anthropic and Supabase

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

Anthropic objects Supabase objects How this pairing syncs
API Keys Key metadata — name, owning workspace, status, creator — from /v1/organizations/api_keys; the secret value is never returned. Read-only, useful for a security key inventory. Database Functions Postgres functions that can transform or validate synced rows. API Keys is specific to Anthropic and Database Functions to Supabase — each maps to any object or custom field on the other side.
Invites Pending organization invitations from /v1/organizations/invites; read to track who has been invited to the org but has not yet accepted. Storage Object Metadata File metadata rows that can be joined to synced application data. Invites is specific to Anthropic and Storage Object Metadata to Supabase — each maps to any object or custom field on the other side.
Message Batches Asynchronous batch jobs at /v1/messages/batches; the connector polls processing_status and reads per-request results keyed by custom_id once a batch has ended. Tables Standard Postgres tables; the primary two-way sync target. Message Batches is specific to Anthropic and Tables to Supabase — each maps to any object or custom field on the other side.
Models Claude model catalog from /v1/models with model IDs, context window, max output, and capability flags; snapshotted into a config table so applications avoid hardcoding model IDs. Views Read-side projections exposed to outbound syncs. Models is specific to Anthropic and Views to Supabase — each maps to any object or custom field on the other side.
Usage Report (messages) Time-bucketed token usage (uncached input, cached input, cache creation, output) grouped by workspace, model, API key, and service tier from /v1/organizations/usage_report/messages; read-only, queried by date range at 1m/1h/1d bucket width. Schemas Namespaces (public and custom) that scope sync access. Usage Report (messages) is specific to Anthropic and Schemas to Supabase — each maps to any object or custom field on the other side.
Cost Report Daily USD cost broken down by workspace, model, and cost type from /v1/organizations/cost_report; read-only, polled by date range for chargeback and FinOps reporting. auth.users Managed authentication users, often mirrored into CRM or support systems. Cost Report is specific to Anthropic and auth.users to Supabase — each maps to any object or custom field on the other side.

How changes propagate between Anthropic and Supabase

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

Anthropic Supabase Interval-based propagation

DetectionStacksync polls Anthropic for changes on an incremental schedule, reading only records changed since the previous pass. Polling.

DeliveryEach detected change is applied to Supabase as a row-level write, with types converted between the two schemas.

Supabase Anthropic Sub-second propagation

DetectionSupabase pushes changes as they happen — webhook events backed by change data capture. Log-based CDC via Postgres logical replication, the same WAL feed that powers Supabase Realtime.

DeliveryAnthropic does not accept inbound record writes, so this direction carries requests rather than records: Anthropic's output flows back as field updates on the originating Supabase records.

Rate-limit considerations

  • Anthropic: Messages API limits are per usage tier: requests-per-minute plus input- and output-tokens-per-minute, surfaced in anthropic-ratelimit-* response headers with retry-after on 429. Usage/cost reports recommend polling at most once per minute.
  • Supabase: SQL access is bounded by connection limits (pooled connections are provided); the REST layer is subject to the platform's limits.

How the Anthropic and Supabase connectors work

Anthropic

Integration surface
REST — Messages API at api.anthropic.com/v1 plus the Admin API (/v1/organizations/*) for organization, usage, and cost data
Authentication
API key in the x-api-key header for Messages, Models, Files, and Batches endpoints; the Admin API requires a separate Admin API key (sk-ant-admin...) with organization-admin permission. Every request also sends an anthropic-version header.
Change detection
Polling. Usage and cost reports are queried by time bucket (1m/1h/1d) over a date range; list endpoints paginate with has_more/next_page (or after_id). No general-purpose data-change webhooks (webhooks exist only for Managed Agents session state).
Capabilities

Rate limits
Messages API limits are per usage tier: requests-per-minute plus input- and output-tokens-per-minute, surfaced in anthropic-ratelimit-* response headers with retry-after on 429. Usage/cost reports recommend polling at most once per minute.

Supabase

Integration surface
Direct PostgreSQL wire protocol connection, plus an auto-generated REST API (PostgREST)
Authentication
Database credentials (connection string) for SQL access; API keys (anon / service role) for the REST layer
Change detection
Log-based CDC via Postgres logical replication, the same WAL feed that powers Supabase Realtime; database webhooks can also fire on row changes
Capabilities
