HeaderHawk vs building it yourself

This is the real default. A CSP report endpoint is a POST handler that writes a JSON body somewhere, and any competent team can have one running in an afternoon for approximately nothing. Most people weighing a CSP reporting service are really weighing it against that afternoon.

It is a fair fight, and worth being honest about: the endpoint is not the hard part. What follows it is — grouping, noise, retention, quota control, and a screen somebody will actually open on a Tuesday.

HeaderHawk is built out of exactly those pieces, so this page is mostly a description of what you would be signing up to build.

Side by side

Every figure in the a DIY endpoint column is quoted from their own published page, read on 11 September 2026. The HeaderHawk column is generated from the same data as our pricing page, so it cannot drift from it. Prices change — check theirs before you decide, and tell us if this table is out of date.

	a DIY endpoint	HeaderHawk
Free plan	AWS free tier: “one million requests” and “400,000 GB-seconds per month”	Free: $0, 3 sites, 10,000 reports a month, 15-day retention, no card
Cheapest paid plan	“$0.20 per one million requests” plus “$0.0000166667 per GB-s”, plus storage, plus your time	Team, $39/month or $390/year
Sites on that plan	As many as you deploy	10 sites
Reports a month	Whatever you provision for	100,000
Report retention	As long as you pay to store it	30 days
Team members	Your own IAM	10
Trial	Not applicable	30-day Team trial, no credit card

Lambda prices are x86 in US East (N. Virginia) and exclude storage, queries and everything downstream of the endpoint. The point of the row is that ingestion is nearly free; the cost is in the rest.

What a DIY endpoint does better

A comparison that finds no advantage anywhere is the one readers stop trusting. These are the things HeaderHawk does not do.

The reports never leave your account: No third party, no data processing agreement, no vendor review. For some organisations that ends the discussion before price is mentioned, and it is a completely legitimate place to end it.
Ingestion really is almost free: At AWS's published Lambda rate a million reports costs twenty cents to receive, and the first million requests a month are in the free tier. No plan limit, no overage, no per-report price at any volume.
Retention and schema are yours: Keep reports for seven years if you want to. Join them to your deploy log, your CDN logs or your incident tickets. No hosted product will let you do that, including this one.
It fits what you already run: If your organisation already has a log pipeline, a warehouse and dashboards on top of them, CSP reports are just another stream — and the marginal cost of one more stream is much lower than the cost of the first one.

Where HeaderHawk is stronger

Each of these is something the product does today, not something on a roadmap.

Grouping is the work, and it is already done: A busy site produces thousands of reports of a handful of problems. Grouping by directive, blocked source and page — with first-seen, last-seen and counts per group, and the raw reports still reachable underneath — is what turns that into a list you can read.
Noise classification you would otherwise learn the hard way: Browser extensions, data:, about: and blob: URLs, and bot traffic dominate a real CSP feed. HeaderHawk ships patterns for all three, holds them out of alerts and keeps them visible in the dashboard. Most DIY endpoints learn this list by being paged by it.
The browser's report format is not one format: Ingestion accepts both the legacy report-uri body and report-to's reports+json envelope, and normalises the differences between what browsers actually send — including whether you get a source file, line and column at all.
Alerting with a confidence model behind it: Violations accumulate into 15-minute windows scored by browser-family diversity: two or more families, or twenty signal reports from one, alerts immediately; quieter windows go to a daily or weekly digest. Writing that rule is easy. Knowing it is the rule you want takes a few months of being woken up.
The parts nobody scopes: Report-domain validation so that someone else's site cannot fill your bucket, quota and abuse limits, retention deletion that actually runs, and a UI a second person can use. None of these are hard. All of them are work, and none of them ship the feature you were working on.

Which one to pick

Build it yourself if…

The data cannot leave your infrastructure. That requirement is not negotiable and no amount of product beats it.
You already have the pipeline. Where logs, storage and dashboards exist, CSP reports are a small addition and a hosted tool is a duplicate bill.
You are curious. It is a genuinely good way to learn how CSP reporting works, the volumes are small at first, and you can always stop.

Try HeaderHawk if…

The endpoint is not the interesting part of your week. The Free plan costs less than the afternoon does, and you can keep the DIY endpoint running alongside it.
Your first attempt is now a table of 400,000 rows nobody looks at. That is the usual failure, and it is a grouping and noise problem rather than a storage one.

HeaderHawk has no data export, no API for reading your data, no HTTP response-header monitoring, no configurable alert thresholds and no spike detection. If any of those is a requirement, the comparison above is already decided.
