Stop guessing. Start watching.

Monitor APIs, debug webhooks, manage feature flags, and catch schema drifts — before anything breaks.

The Problem

Your API stack is held together by
hope, logs, and too many tabs.

Most engineering teams use 4-5 separate tools for reliability. Different logins, different dashboards, zero correlation. Until something breaks and no one knows why.

Your API goes down

Your uptime tool says 200 OK. But the response body is empty. Customers see broken pages. You find out from Twitter.

Webhooks go missing

Stripe sends a payment webhook. Your endpoint crashes silently. No logs, no replay, no idea what the payload looked like.

Feature ships break prod

No feature flags = full deployment = full rollback. One bad commit takes down the whole product. LaunchDarkly costs $300+/mo.

Stripe silently changes their API

A field gets renamed. Your integration breaks. You discover it 3 days later from a customer complaint. No one monitors third-party APIs.

Depify solves all four. In one platform. Starting at Rs. 1,999/mo.
PLATFORM MODULES

Four powerful modules, one platform. Zero blind spots.

Each module works independently or together. Mix and match. All share one team workspace.

API Monitor
Beyond uptime -- validate everything
  • Response body validation -- not just status codes
  • Schema drift detection on every check
  • SSL expiry monitoring + certificate chain validation
  • Multi-region checks from 10 global locations
  • Alerts via Email, Slack, Telegram, MS Teams, Webhooks
Read the deep dive
// Check result -- real-time
✓ GET api.example.com/v2/users
Status: 200 OK · 142ms · Schema: matched
SSL: Valid · Expires in 89 days
✗ POST api.example.com/v2/orders
Status: 500 · 3,241ms · Schema: DRIFT DETECTED
→ Field "order_id" type changed: string → integer
→ Alert sent to #ops-alerts on Slack
Webhook Debugger
Capture, inspect, replay -- never miss a webhook
  • Smart parsing for Stripe, GitHub, Shopify, and 20+ providers
  • Automatic signature verification per provider
  • Forward to localhost for local development
  • Payload editing, bulk replay, and event filtering
  • Human-readable event summaries (not raw JSON)
Read the deep dive
// Incoming webhook captured
POST /webhooks/stripe · Stripe-Signature: t=1711...
→ Provider: Stripe (auto-detected)
→ Event: payment_intent.succeeded
→ Summary: "Payment of Rs. 4,999 succeeded for saurabh@mobivend.in"
→ Signature: ✓ Valid
→ Forwarded to localhost:3000/webhooks → 200 OK
Feature Flags
Ship fast, roll back faster
  • Percentage rollouts with sticky hashing (consistent UX)
  • User targeting with 11 operators (equals, contains, regex, etc.)
  • Multi-variate A/B/C testing and kill switches
  • Scheduled rollouts and environment overrides
  • REST API that works from any language or framework
Read the deep dive
// Flag evaluation trace
depify.evaluate("new_checkout", { id: "user_123", plan: "pro" })
→ Check overrides: none
→ Check segments: "pro_users" matched ✓
→ Rollout: 65% (bucket 42 < 65) ✓
→ Result: true · Reason: segment_match · 0.2ms
API Intelligence
Schema drift detection + provider change tracking
  • Auto-infer JSON schemas and detect breaking changes
  • Field-level diffs with severity classification
  • Track 59+ providers via RSS feeds and deep blog scraping
  • Impact classification: breaking, deprecation, security, migration
  • Countdown deadlines with action guidance
Read the deep dive
// Schema drift detected
Stripe API /v1/payment_intents · Schema check #847
- user_id: string → ✗ REMOVED (BREAKING)
+ userId: string → ✓ ADDED
~ amount: integer → number (TYPE CHANGED)
Severity: BREAKING · Action Required
Deadline: April 30, 2026 (34 days remaining)
→ Alert sent to 3 channels

Depify offers three ingestion tiers to fit your infrastructure: an HTTP forward proxy that sits in front of your outbound traffic, a Kubernetes sidecar that transparently intercepts pod-level requests, and an OpenTelemetry-compatible receiver for teams already using OTel collectors. All three methods capture full request/response pairs without requiring any code changes to your application.

When Depify detects a schema change, it automatically generates a structured diff showing exactly what fields were added, removed, or modified. Each change is classified by severity (breaking, additive, or cosmetic). On Pro plans, our AI analysis engine provides a plain-English explanation of the change and its potential impact on your codebase. Alerts are delivered via your configured channels (Slack, email, PagerDuty) in under 200ms.

Absolutely. Depify is designed to be modular — four modules, use any combination. You can start with just API monitoring, or only use the webhook debugger, and add other modules as your needs grow. All four modules (API Monitor, Webhook Debugger, Feature Flags, and API Intelligence) are included in every plan — the difference between tiers is usage limits, not feature availability. Mix and match to build the workflow that fits your team.

Depify feature flags are evaluated at the edge via lightweight SDKs (Ruby, Node.js, Python, Go). You can create boolean on/off flags, percentage-based rollouts, or multivariate flags with multiple variants. Targeting rules let you route traffic by user ID, region, account plan, or any custom attribute. Flag changes propagate instantly — no deploys required. The dashboard shows real-time evaluation counts and error rates per flag.

For local development and testing, you can spin up the full Depify stack using Docker Compose. For production workloads, we recommend our managed cloud platform for the best reliability and zero operational overhead. A fully self-hosted enterprise option with on-premise deployment is on our roadmap and coming soon — contact our sales team if this is a requirement for your organization.
