The short version

  • Only Honeycomb has a free tier, so it costs nothing to try first.
  • Each has a real cost: Honeycomb free tier caps at 20 million events per month and 100 million metrics data points; Thought Machine a core replacement is a two to four year programme at an established bank, and the licence is a minority of total cost against system integrator fees, parallel running and data migration.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Honeycomb

  • Free tier caps at 20 million events per month and 100 million metrics data points
  • Pro tier starts at $150 per month for only 50 million events, with cost scaling per additional event block up to its 750 million event ceiling
  • Enterprise tier's event and data point volumes are variable and its price is custom, requiring direct sales contact
  • Telemetry Pipeline is billed separately at $0.10 per GB on top of the base plan price

Thought Machine

  • A core replacement is a two to four year programme at an established bank, and the licence is a minority of total cost against system integrator fees, parallel running and data migration.
  • The smart contract model presumes a bank can write and maintain Python financial products, and institutions without that engineering capability end up outsourcing the very flexibility they bought.
  • Cloud infrastructure cost sits with the bank and is not trivial at scale, so total cost of ownership comparisons against a hosted legacy core often miss a large recurring line.
  • Thought Machine has made two rounds of job cuts pursuing profitability, which is a legitimate supplier stability concern for a system a bank expects to run for fifteen years.
  • The functional footprint is core ledger and product engine, so origination, collections, regulatory reporting and channels all come from other vendors, and the integration estate around Vault is the bank's problem to design and own.
