Cloudflare Workers bills CPU time, not duration, which inverts everything you know from AWS Lambda. Here is the 2026 pricing, three worked monthly bills, and the 3-millisecond breakpoint that decides your cost.
Render's advertised prices hide the real bill. In 2026 your cost is three stacked layers: a workspace plan, per-service compute, and metered usage. A solo production app starts near $13/mo (not $7), a small team app around $115/mo. Here is the arithmetic, with three worked 30-day bills.
Sentry pricing in 2026 is event-based: a free Developer plan, Team at $26/mo and Business at $80/mo (billed annually), each including 50,000 errors, 5M tracing spans, 50 replays and 5 GB of logs. Everything above that baseline is pay-as-you-go, and that overage, not the sticker, is your real bill. Errors run about $0.15 to $1.11 per 1,000 and spans about $1.60 to $4.00 per million, so tracing usually dominates. Below: the full per-unit ladder, three modeled 30-day bills, and why the Business plan includes the same base quotas as Team at three times the price.
Cloudflare R2 pricing in 2026 charges for storage and operations but never for egress: Standard storage is $0.015/GB-month, Class A writes $4.50/million, Class B reads $0.36/million, with a permanent free tier of 10 GB plus 1M/10M operations. Free egress is the whole pitch, and it moves your bill onto operations, not gigabytes. Below: three real 30-day bills versus Amazon S3 and Backblaze B2, and the Infrequent Access trap that doubles a write-heavy bill.
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 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.
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'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.
Railway's $5 and $20 plans are usage floors, not your bill. Here is the real 2026 metered invoice at three app sizes, from a $5 side project to a $278/month scaled product.
Three modeled 30-day Vercel bills, the $0.15-per-GB meter that actually moves the number, and when Hobby, a VPS, or a bundled host wins.
OpenRouter takes 5.5% on credit purchases with a $0.80 minimum, then passes provider rates through. Here is the real 30-day bill across Anthropic, OpenAI, and Mistral at four workload mixes, with the anti-patterns where the routing tax stops being worth it.
