Tools
Things we built because we needed them.
Free, no sign-up, no logging. Everything runs in your browser — nothing you paste is transmitted anywhere, which matters when the payload you are debugging is real.
- utility
EDI viewer & validator (X12 + EDIFACT)
Parse an X12 or EDIFACT interchange into named segments and elements, and check the control references and segment counts actually agree — the usual reason a partner rejects a file.
Open - utility
X.509 certificate decoder
Read a PEM certificate's subject, validity, key and extensions — and see whether its key survives a quantum-capable adversary.
Open - utility
JSON ↔ XML converter
Convert between JSON and XML in both directions, in your browser. Nothing you paste leaves the page.
Open - utility
CSV ↔ JSON converter
Convert flat files to JSON and back, with a real RFC 4180 parser — quoted delimiters, embedded newlines and leading zeros all survive.
Open - utility
OpenAPI linter
Lint an OpenAPI 3.x spec for the things that break downstream — missing operationIds, undeclared path parameters, operations with no success response.
Open - utility
MCP tool-definition linter
Lint MCP or function-calling tool definitions for what fails silently — descriptions that don't say when to use a tool, undescribed parameters, missing safety annotations.
Open - utility
OpenAPI → agent tools
Convert an OpenAPI spec into MCP or function-calling definitions — and see which operations probably shouldn't be on an agent's tool surface at all.
Open - calculator
Agent blast-radius calculator
Assume the agent misuses every tool it has. What is the worst outcome, what is irreversible, and do your controls actually constrain it?
Open - utility
Prompt secret scanner
Check a prompt or assembled context for credentials, tokens, connection strings and personal data before it leaves the building.
Open - calculator
Agent cost & context calculator
An agent loop re-sends its whole conversation every turn, so cost grows with the square of turn count. See what your loop actually costs, and what caching changes.
Open - calculator
Agent-readiness scorecard
Twelve questions about your estate, none about which model you use. Scores whether an agentic workflow would survive security review.
Open - calculator
iPaaS readiness assessment
Thirty questions across estate, connectivity, security, delivery, operations and organisation — scored, with each gap's actual consequence named.
Open - calculator
Modernisation roadmap generator
Phase structure, exit criteria and indicative durations for an integration modernisation — including which phase usually absorbs the overrun.
Open - calculator
Migration risk register
Twenty risks that materialise on integration migrations, each with an early warning sign. Score them for your estate and export.
Open - calculator
Cutover runbook builder
A runbook skeleton with rollback points marked and the go/no-go placed where rollback still fits in the window.
Open - calculator
Interface catalogue builder
Build the inventory every integration programme needs and almost nobody has — then see what it tells you about ownership, partner dependencies and crypto exposure.
Open - calculator
Migration wave planner
Sequence an interface catalogue into delivery waves — pilot on the safe work, take the hard and critical work early, and start partner conversations first.
Open - calculator
Function Point estimator
IFPUG function point counting, with the five components restated for integration rather than for screens — and every step of the arithmetic shown.
Open - calculator
Platform migration assessor
Moving between integration platforms? See which capabilities carry across, which have no equivalent, and roughly what it costs — with the arithmetic shown.
Open - utility
Fixed-width flat file parser
Parse fixed-width extracts with multiple record types and implied decimals — the shape real SAP, banking and retail files actually take.
Open - utility
webMethods flow reader
Read a flow.xml and node.ndf into a readable step tree, service dependency list and hard-coded value report — the first artefacts a migration assessment needs.
Open - utility
SAP IDoc viewer
Parse an XML IDoc into a named control record and segment hierarchy, and check it carries what SAP needs to route it.
Open - utility
SWIFT MT & ISO 20022 viewer
Read MT messages block by block, or ISO 20022 payment XML — recomputing the total against the declared control sum.
Open - utility
HL7 v2 message viewer
Parse an HL7 v2 message into named segments and fields, with the MSH numbering quirk handled correctly and the header validated.
Open - utility
XSLT tester
Run an XSLT 1.0 transform in your browser — and when the output comes back empty with no error, find out which namespace mismatch stopped every template from firing.
Open - utility
XPath tester
Evaluate XPath against XML and see the concrete path each match came from — with default namespaces detected and bound, which is why most XPath silently matches nothing.
Open - utility
CI/CD workflow security linter
Scan a GitHub Actions or GitLab CI file for the pipeline failures that get exploited — script injection from pull request titles, unpinned actions, and pull_request_target building fork code.
Open - utility
Regex tester & ReDoS checker
Test a pattern, then find out whether someone can hang your service with it — catastrophic backtracking found by structural analysis and by measurement.
Open - utility
Webhook signature verifier
Check an HMAC webhook signature for GitHub, Stripe, Slack or Shopify — and when it fails, find out which near-miss of your payload the sender actually signed.
Open - calculator
SLA & error budget calculator
Serial dependencies multiply. See what your chain actually achieves, whether your target is reachable at all, and which dependency owns most of the downtime.
Open - calculator
Retry & backoff simulator
Model a retry policy against the caller's deadline, and see how many attempts happen after everyone has given up — plus what nested retries do to the service at the bottom.
Open - utility
JSONPath tester
Evaluate JSONPath against a payload and see the concrete path each match came from — filters, recursive descent, slices and regex included.
Open - utility
JSON Schema generator
Infer a draft 2020-12 schema from sample JSON, merging every array element so optional fields are not marked required.
Open - utility
Encoding & mojibake fixer
Repair text mangled by the wrong codepage — café back to café — and expose invisible characters like a stray byte order mark.
Open - utility
JSON formatter & validator
Format or minify JSON, with errors located by line and column instead of a bare character offset.
Open - utility
JSON diff
Compare two payloads by structure rather than text. Reordered keys are ignored; type changes are flagged.
Open - utility
Epoch & timestamp converter
Convert Unix time to dates and back, with automatic seconds-versus-milliseconds detection.
Open - utility
Base64 encoder & decoder
UTF-8 safe in both directions, including the URL-safe variant used by JWTs and OAuth.
Open - utility
UUID & ULID generator
Generate UUID v4, time-ordered UUID v7 or ULIDs, in bulk, from a cryptographically secure source.
Open - utility
JWT decoder
Decode a JSON Web Token and read its claims, with expiry in plain language. Runs in your browser — the token is never transmitted.
Open - utility
Cron expression explainer
Turn a cron expression into plain English and see its next five runs — including the day-of-week trap that makes jobs fire twice as often as intended.
Open - calculator
Interface math calculator
How many interfaces does point-to-point actually cost you, against routing through a layer? Run it on your own estate size.
Open - calculator
Post-quantum migration matrix
Paste a cryptographic inventory and see what each algorithm becomes under NIST's post-quantum standards — with migration difficulty driven by where the key lives, not just which algorithm it is.
Open - calculator
Post-quantum exposure calculator
Data you send today has to stay secret for years. Check whether it outlives your own migration plan — and your own assumptions.
