The short version

  • Only Neovim has a free tier, so it costs nothing to try first.
  • Each has a real cost: Neovim no official first-party GUI is shipped; Neovim itself is a terminal-based editor and only maintains a curated list of third-party GUI front-ends; 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.
  • They diverge on capability: Neovim covers Async job control, Thought Machine covers Smart contract product engine.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

Neovim

  • No official first-party GUI is shipped; Neovim itself is a terminal-based editor and only maintains a curated list of third-party GUI front-ends
  • Licensing is not uniform: code contributed after commit b17d96 is Apache 2.0, but code carried over from Vim (tagged vim-patch) remains under Vim's own license
  • Built-in LSP client and Tree-sitter integration are frameworks requiring separate configuration or plugins for language servers/grammars to be useful, not out-of-box language support
  • No official iOS, Android, or web build

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.
