Fly.io Pricing in 2026: The Real 30-Day Bill

Fly.io pricing in 2026 is pure pay-as-you-go: you pay per second for the Machines (micro-VMs) you actually run, not a fixed plan. A small always-on app on a shared-cpu-1x 256MB Machine costs about $2.02 a month; a two-Machine production SaaS with Postgres and Redis lands near $29 a month; a three-region app on performance Machines runs about $226 a month. The old Hobby, Launch, and Scale plan names were retired in the October 2024 pay-as-you-go switch, and the biggest lever left is a machine reservation, which cuts committed compute by 40%.

Cloudinary Pricing in 2026: What You Actually Pay

Cloudinary pricing in 2026 runs on credits: 1 credit equals 1,000 transformations, 1 GB of managed storage, or 1 GB of net delivery bandwidth. Free gives 25 credits, Plus is $99/mo ($89 annual) for 225 credits, and Advanced is $249/mo ($224 annual) for 600 credits. Because credits are one shared pool, delivery bandwidth is usually the line that runs out first, and it works out to roughly $0.40 per GB, far above a raw CDN.

Resend Pricing in 2026: What You Actually Pay

Resend pricing in 2026 runs from a permanent Free tier (3,000 emails per month, capped at 100 per day) to Pro at $20 per month for 50,000 emails or $35 for 100,000, then Scale from $90 up to $1,150 per month for 2.5 million emails, with $0.90 per 1,000 overage. The catch the pricing page hides: your real cost is the effective price per 1,000 emails, which swings from $0.40 to $3.33 on the same $20 plan depending on how full your tier is. Budget by the tier you actually fill, and watch the separate marketing-contacts meter.

Firebase Pricing in 2026: What You Actually Pay

Firebase pricing in 2026 is free to start (Spark plan: 50K Firestore reads, 20K writes, and 20K deletes per day, 1 GiB stored), then pay-as-you-go on Blaze at $0.06 per 100K reads, $0.18 per 100K writes, and $0.02 per 100K deletes. A typical 5,000-DAU app costs about $12/month, but there is no hard spending cap, so one unbounded query or a looping Cloud Function can turn a $12 bill into thousands overnight.

MongoDB Atlas Pricing in 2026: What You Actually Pay

MongoDB Atlas pricing in 2026 runs from a free 512 MB M0 cluster, to a usage-based Flex tier capped at $30/month, to dedicated clusters that start at $0.08/hour (about $58/month for an M10) and climb with RAM. The surprise is the jump from the $30 Flex cap to a dedicated cluster that bills 24/7 whether traffic flows or not.

Clerk Pricing in 2026: What You Actually Pay Per User

Clerk's Free plan covers 50,000 monthly retained users (MRU) in 2026, so most side projects and early-stage SaaS pay $0. Pro is $25/month with 50,000 MRU included, then $0.02 per user in the 50,001 to 100,000 band. The bill that surprises teams is not per-user overage; it is the feature add-ons, B2B Auth at $100/month, Administration at $100/month, and extra Enterprise SSO connections at $75/month each. Clerk also bills retained users, not signups, so anyone who does not return 24 hours after signing up costs nothing.

Twilio SMS Pricing in 2026: What You Actually Pay

Twilio charges $0.0083 per SMS segment in the US as of 2026, but that sticker price is not what lands on your bill. Carrier pass-through fees ($0.0025 to $0.0062 per segment), A2P 10DLC registration charges, number rental, and multi-segment messages typically push the real delivered cost to $0.012 to $0.025 per message, roughly 1.5x to 3x the advertised $0.0083.

Stripe Fees in 2026: What You Actually Pay

Stripe's US rate in 2026 is 2.9% + $0.30 per online card charge with no monthly fee, but the flat 30-cent fee and five add-on meters (international +1.5%, currency conversion +1%, instant payouts 1.5%, disputes $15, Billing 0.7%) push most businesses to an effective 3.2% to 13%. Your real rate is a function of your average order value and how you get paid.
