audit_stackAudit an existing stackread-onlyAssess the stack an existing app runs on and recommend what to do. For each service: its plan, cost now and in 12 months, must-haves it lacks, cost jumps in the next year, lock-in, and a verdict (keep, watch, optimise, switch or fix) with savings, one-off moving cost and the month a switch pays off. Then a scorecard (cost, requirements, ready to scale, lock-in; A to F, weighted by priorities 0-3) and recommendations ranked by what the user cares about. Categories the requirements need but nothing covers are suggested too. Use the vendor ids from detect_stack; pass plan_id when the user knows t…
check_fitCheck requirement fitread-onlyFor each vendor, show whether each requirement is met on its cheapest plan, needs a higher tier (with that tier's cost), or is missing.
compare_architecturesInterview, then compare architecturesread-onlyAsks the questions that decide an architecture (static or dynamic, who signs in, how much data, uploads and media, background jobs and live updates, data sensitivity, threat profile, cost of downtime, who runs the servers), then rates every architecture against the answers: static site on a CDN, frontend with Supabase, serverless Next.js on Vercel, Cloudflare Workers, containers on DigitalOcean App Platform, one server, one server behind Cloudflare, Firebase, or on the phone with no server. Returns the top three with a 0-100 fit, what each service does, the monthly cost now and at forecast, st…
compare_vendorsCompare vendors in a categoryread-onlyRank vendors in one category at a given scale. Vendors meeting every must-have come first, then cheapest. Ranking is by cost and fit only. Example: {"category":"auth","mau":50000,"requirements":[{"capability":"auth.saml_sso"}]}.
delete_accountDelete your Kong Reviews accountcan change or delete dataPermanently delete the signed-in user's Kong Reviews account: their GitHub sign-in link and every saved stack. This cannot be undone. Only call it when the user explicitly asks to delete their account, after telling them what will be removed; pass confirm exactly as "delete my account". Needs sign-in.
delete_saved_stackDelete a saved stackcan change or delete dataPermanently delete one of the signed-in user's saved stacks by id. Only call it when the user explicitly asks to delete that stack; confirm the name first. Needs sign-in.
detect_stackDetect an existing app's stackread-onlyWork out which services an existing app runs on, from its files, a public GitHub repo, or its live website. From an AI coding app, read the project yourself and pass the files that say the most: package.json (or requirements.txt, pyproject.toml, Gemfile, go.mod, pubspec.yaml, Podfile), .env.example (names only, never secret values), and deploy configs (vercel.json, netlify.toml, fly.toml, render.yaml, .do/app.yaml, wrangler.toml, firebase.json, Dockerfile). Returns each catalogue vendor found with its evidence and confidence, services the catalogue can't price yet, frameworks and platforms. Ru…
diff_stackPrice a code change (pull request)read-onlyWhat a code change does to an app's bill: pass the files before (base_files) and after (head_files) the change, such as package.json, requirements.txt, .env.example (names only) and deploy configs. Returns the services added and removed, each priced now and in 12 months at the given users, with cheaper options and cost jumps, the change in monthly cost, and comment_markdown ready to post on a pull request. Use it before adding a paid service or SDK, or to review a pull request. Rules only; nothing is stored.
estimate_costEstimate monthly costread-onlyMonthly cost for one vendor at a given scale. Give mau (monthly active users) and a usage profile, or exact usage numbers. Picks the cheapest plan that fits unless plan_id is set. Example: {"vendor_id":"clerk","mau":25000}.
evaluate_changeStay, optimise or switchread-onlyWhen something changes (bill too high, growth, a missing feature such as SSO, a renewal), compare staying on the current plan, optimising with the same vendor, and switching vendor, including one-off switching cost and the month switching pays off. Example: {"category":"auth","current":{"vendor_id":"clerk","plan_id":"pro"},"mau_now":11000,"monthly_growth":0.18,"requirements":[{"capability":"auth.saml_sso"}]}. How to present the result: show stay, optimise and switch side by side with cumulative cost at each month given, the break-even month and any problems; show every caveat word for word.
extract_requirementsExtract requirements from a PRDread-onlyTurn PRD or spec text into structured requirements (scale, capabilities, compliance, regions, budget) for plan_stack, without planning. recommend_stack does both in one call. Each requirement quotes the sentence it came from. Show them to the user to confirm before planning. Without a model on the server it reads the PRD with keyword rules (mode "rules") and also returns the capability vocabulary and instructions: as an assistant, prefer doing the extraction yourself and use the rules result only as a starting point.
find_cost_cliffsFind cost cliffsread-onlyScan a range of user counts for one vendor and report where cost jumps: forced plan upgrades and points where usage charges start. Example: {"vendor_id":"clerk","from_mau":1000,"to_mau":200000}.
find_perksFind startup perksread-onlyStartup credits for the given vendors, and whether you qualify based on your bank, incorporation provider, accelerator or funding. Example: {"vendor_ids":["supabase","posthog"],"founder":{"gateways":["mercury"]}}.
get_pricingGet vendor pricingread-onlyStructured pricing and capabilities for one vendor: every plan, base fee, metered usage, limits, unmodelled costs, lock-in notes, source URL and verification date.
get_saved_stackOpen a saved stack with current pricesread-onlyRe-run a saved stack or audit with today's catalogue and compare it with when it was saved: monthly cost then and now, picks (or plans) that changed, vendors whose pricing changed and, for audits, the grade; and any bills recorded with record_bills next to the estimate. Use it when the user asks about a stack they saved, or whether prices moved. Pass the id from list_saved_stacks. Needs sign-in. How to present the result: show the stack table (pick and runner-up per category, monthly cost now and at forecast) and the totals. For each price give its source's verified date, or say it is unverifi…

list_capabilitiesList capabilitiesread-onlyList capability ids (features, compliance, regions) that requirements can reference, e.g. auth.saml_sso, region.eu, payments.merchant_of_record.
list_saved_stacksList your saved stacksread-onlyList the stacks the signed-in user saved, newest first, with their monthly cost when saved and a link to each. Use it when the user mentions "my stacks", "the stack I saved" or a saved stack by name; then call get_saved_stack for one of them. Needs sign-in. How to present: a short table of name, saved date and monthly cost when saved, each name linked to its share_url.
list_vendorsList vendorsread-onlyList vendors in the pricing catalogue, optionally for one category (hosting, database, auth, email, payments, observability, ai, edge, app_store, coding).
plan_stackRecommend a stack from requirementsread-onlyGiven confirmed requirements as capability ids, recommend a vendor per category with a runner-up, requirement fit, cost now, cost at forecast scale, year-one cost after perks, cost cliffs, trade-offs and blockers. Use recommend_stack instead when you only have a plain-language description. Example: {"mau_now":5000,"mau_forecast":20000,"profile_id":"booking_marketplace","requirements":[{"capability":"auth.google"},{"capability":"payments.merchant_of_record"}],"founder":{"gateways":["mercury"]}}. How to present the result: show the stack table (pick and runner-up per category, monthly cost now a…
project_stackProject stack cost over timeread-onlyMonth-by-month cost for a whole stack as users grow, with startup perks applied if requested, plus cost cliffs (forced plan upgrades, sharp jumps, credits running out). Example: {"vendors":[{"vendor_id":"supabase"},{"vendor_id":"vercel"}],"start_mau":2000,"monthly_growth":0.15,"months":24,"apply_perks":true,"founder":{"gateways":["mercury"]}}.
recommend_stackRecommend a stack from a descriptionread-onlyStart here. Describe the product in plain language and get a recommended stack with costs now and at scale, in one call. Write the description as the user would: what the product does, who signs in and how, how it charges, which emails it sends, compliance or data-region needs, and expected users now and in 12 months. Example: "A booking app for yoga studios. Members sign in with Google and pay a monthly subscription. Studios get paid out. EU data. 2,000 users at launch, 20,000 within a year." Pass a PRD as the description if you have one. Numbers you pass (mau_now, mau_forecast, budget_monthl…
record_billsRecord what a stack or account actually costRecord what the user actually paid each service in a month, on one of their saved stacks or audits, and compare it with the estimate at the users it was saved with. Without id, the bills are kept on the account, not on a stack (for someone who has not saved one): they are recorded and listed, with no estimate to compare, and can be moved onto a stack later on the Billing page. Pass bills (month as YYYY-MM, the service as vendor_id or name as on the invoice, amount_usd), or csv: a billing export with columns for month or date, service or vendor, and amount, or invoice_text: an invoice's text as…
save_stackSave a stack to your accountSave a recommended stack, or an audit of an existing app, to the signed-in user's Kong Reviews account so it can be reopened later and compared with current prices. Pass the share_url from recommend_stack, plan_stack or audit_stack (preferred) or the plan_stack arguments, plus a short name such as "Yoga booking MVP". Afterwards, offer update_saved_stack with alerts: true so they are emailed when prices or cost jumps change it. Needs sign-in: if the user isn't signed in, the app will ask them to connect their Kong Reviews account. Only save when the user asks to keep or save a stack.
search_directorySearch the service directoryread-onlySearch the directory of developer services (hosting, databases, auth, email, SMS, payments, analytics, monitoring, LLM APIs, vector databases, search, CMS and more): what each provider sells, its free tier, its lowest paid price, caveats and the pricing page it came from. Wider than the cost engine: use it to find options or check a provider the other tools don't price. Entries marked candidate have no prices yet. Example: {"query":"postgres","category":"database"}.
search_showcaseSearch the startup showcaseread-onlyBrowse products startups have built and the stack each runs on: what it is, whether it is a website, a mobile app, both or a desktop app, its category and pricing, and every framework and service it uses (services link to the directory and, where priced, the cost engine). Use it to find real stacks to learn from, e.g. apps built with Supabase. Results list each filter value with counts. Example: {"tech":"supabase","form":"app"}.
update_saved_stackUpdate a saved stack: users, name or alertsChange one of the signed-in user's saved stacks or audits: its name, how many users it has now (mau_now) or expects (mau_forecast), and whether to email them when it changes (alerts). With alerts on, Kong Reviews checks it every day and emails when a vendor's price change moves its monthly cost, when a cost jump or a startup credit running out is about 45 days away, and once a month to ask for the current user count. Alerts need a confirmed email: pass email to send the confirmation link (GitHub sign-in shares no email). Updating users re-prices it and makes today the start of its projection. …
