## HookWatch

HookWatch addresses a narrow but painful problem: webhooks fail silently, providers give up retrying, and teams find out when a customer complains about an unpaid invoice. The product inserts itself between your provider and your application. You create an endpoint in HookWatch, point Stripe, GitHub, Telegram, Shopify, Paddle, or any HTTP webhook source at the HookWatch URL, and HookWatch records every request before forwarding it to your app. The result is a single list of deliveries with status, response code, and timing.

When something fails, you open the delivery to read the exact request headers, body, and the 500 response alongside the full attempt history. Once your handler is patched, one click replays the captured payload — no hand-crafted curl scripts. Repeated failures are grouped into incidents and routed to Slack or a webhook, turning forty identical rows into one alert. The provider's dashboard tells you an attempt went red; HookWatch is built to tell you why it broke and what to do next.

HookWatch is explicitly in early beta. Capture, inspect, and replay are in daily use, but the team asks users to treat pricing, limits, and SLAs as not yet final. Paid tiers check out through Paddle, and the free tier requires no card. Beyond the web UI, the developer experience includes a CLI tunnel for local dev and an MCP server so AI coding assistants can work the failures alongside you.

**Pricing & Plans:** HookWatch is free while in early beta. The Free tier costs $0 and includes 10,000 events per 30 days, one project with three endpoints, one-day payload retention, and manual replay. Paid tiers are purchasable through Paddle: Pay as you go is usage-based at $1.50 per 100,000 events with 7-day retention, Developer is $12/mo (100,000 events included, $1 per extra 100,000), Startup beta is $39/mo (1M events, 30-day retention), and Business is $99/mo (5M events, 90-day retention, priority support). Custom plans cover 10M+ events, VPC deployment, and invoice billing.

- **Delivery capture and forwarding:** Each endpoint gets a HookWatch URL that receives and forwards webhooks, recording status, provider, response code, latency, and attempt count for every delivery.
- **Safe replay and retries:** Re-send an exact captured payload after a fix, with manual replay and retry policies instead of recreating the event by hand.
- **Failure analysis:** Failed deliveries are categorized by reason — signature mismatch, timeout, 5xx, rate limit — so you know what broke without grepping logs.
- **Incidents and alerts:** Recurring failures group into a single incident routed to Slack or a webhook, so a flaky endpoint shows up as one problem.
- **MCP server for AI coding assistants:** Roughly 48 API routes double as MCP tools, letting Claude, Cursor, or Codex list failed deliveries, read request and response, and replay on your behalf.

**Strengths:** One list showing every delivery with request, response, and attempt history; Replay re-sends the exact captured payload instead of requiring manual event recreation; MCP server and CLI bring failure triage into AI coding assistants and local dev; Free tier needs no credit card and paid tiers cost less than running your own dead-letter infrastructure

## Openlayer

Modern companies run dozens of AI systems across business units — copilots, agents, models, and internal tools — but few can list them all, fewer can test them systematically, and almost none can prove to a regulator what any given system did last week. Openlayer was built to close that gap. It organizes AI control into layers that each deliver value on their own: discovery and org-wide inventory with shadow-AI detection, a registration and risk-tiering registry, pre-release evaluation suites, production observability and tracing, security guardrails, compliance mapping, and cost controls.

On the testing side, Openlayer ships a large library of ready-made evaluations covering quality, security, performance, and safety dimensions, including LLM-as-a-judge scorers and session-level metrics. Teams can write custom tests, wire them into CI/CD so regressions block a release, and inspect traces with per-request cost and latency breakdowns when something goes wrong. In production the same tests run on a schedule or in response to live traffic, with alerting integrations and subpopulation analysis that surfaces whether a problem is concentrated in one user segment.

Governance is where Openlayer differentiates most clearly. Systems are registered with an owner, purpose, data sensitivity, and lifecycle stage, and tracked through intake, development, staging, production, and retirement gates. Compliance frameworks such as the EU AI Act and risk models like NIST AI RMF are mapped so policies become checklists with progress tracking, and Enterprise customers can generate evidence packs and deploy on-premise or in air-gapped environments. The result is a platform that spans engineering, security, and compliance workflows rather than serving only one of them.

**Pricing & Plans:** Openlayer offers a free Basic plan covering one member, five projects, 20,000 monthly requests, three months of data retention, the AI test library, CI/CD integration, observability, alerting, and community support. The Enterprise plan is custom-quoted and adds unlimited members and projects, role-based access control, SAML SSO, explainability, data annotation, custom retention, on-premise deployment, compliance reporting, a 99.99% SLA, and white-glove onboarding.

- **AI test library and custom evals:** Dozens of pre-built evaluations cover quality, safety, security, and performance, with LLM-as-a-judge scorers, session-level metrics, and support for writing your own custom tests against your own data.
- **CI/CD regression testing:** Import a repository and run evaluation suites automatically on every change, benchmark each iteration, and block releases when a metric regresses beyond the threshold you define.
- **Observability, tracing, and cost analytics:** Trace every request through multi-step agent workflows, including tool calls and retriever steps, with token counts, latency, cost per request, alerting integrations, and subpopulation analysis.
- **Governance registry and lifecycle gates:** Register each AI system with an owner, purpose, data sensitivity, and risk tier, score inherent risk across multiple dimensions, and move systems through staged approval gates before they reach production.
- **Compliance mapping and audit evidence:** Built-in frameworks such as the EU AI Act and NIST AI RMF turn policy into tracked rules, so you can see progress per project and export the evidence regulators and auditors ask for.

**Strengths:** Covers the full loop from pre-release testing to production monitoring and governance in one platform; Strong compliance and risk-mapping capability built for regulated industries; Generous free Basic plan makes evaluation tooling accessible to small teams; CI/CD integration lets quality gates block releases automatically

**Limitations:** Enterprise pricing is custom-quoted, so costs are not transparent up front; Compliance reporting and the deepest governance features sit behind the Enterprise plan; The breadth of layers can be a lot to adopt at once for teams that only need basic evals; Small free plan limits (one member, five projects) make it a try-it tier rather than a team plan
