The short version

  • Only Deep Code has a free tier, so it costs nothing to try first.
  • Each has a real cost: Deep Code model choice is narrow. Bring your own key covers DeepSeek-V4-Pro and Flash plus the GLM and Mimo coding plans, and no frontier model from OpenAI, Anthropic or Google.; Finxact fiserv sells several core platforms, so a buyer should demand written investment and support commitments for Finxact specifically rather than trusting that the surviving brand implies a protected roadmap.
  • They diverge on capability: Deep Code covers DeepSeek-backed agent, Finxact covers Cloud native core.
  • Prices and features above were last checked on 15 September 2026.

Where each one falls short

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

Deep Code

  • Model choice is narrow. Bring your own key covers DeepSeek-V4-Pro and Flash plus the GLM and Mimo coding plans, and no frontier model from OpenAI, Anthropic or Google.
  • The Pro tier caps included usage at 100 Pro Credits per day rather than offering an unmetered plan.
  • Bring your own key is a paid feature, so the free tier cannot be pointed at your own DeepSeek account.
  • Desktop only, with no editor extension, web version or team seat management as of September 2026.
  • A small, young vendor with no independent review coverage yet, so there is nothing outside the vendor's own site to corroborate the cost claim.

Finxact

  • Fiserv sells several core platforms, so a buyer should demand written investment and support commitments for Finxact specifically rather than trusting that the surviving brand implies a protected roadmap.
  • Core migration is a multi year programme where the licence is a small share of total cost against integration, data migration and parallel running.
  • Buying the core from Fiserv strengthens a relationship that already covers cards and payments, which weakens your negotiating position across the whole estate at renewal.
  • It is a United States product with United States regulatory and product assumptions, so international banks get little from it.
  • Being part of a very large vendor changes the service experience: the responsiveness that made Finxact attractive as a startup is not guaranteed inside a company of Fiserv's scale.

Answered from the vendors’ own pages

Deep Code: Which models does Deep Code run on?

DeepSeek V4 family models, with the vendor's headline built around DeepSeek V4.1. The free tier's included credits run on DeepSeek-V4-Flash. Paid users bringing their own key can also use DeepSeek-V4-Pro, the GLM Coding Plan and the Mimo Coding Plan.

Source
Finxact: Is Finxact still sold under its own name?

Yes. Fiserv acquired it in 2022 and continues to market it as Finxact from Fiserv, winning named core deals with it.

Deep Code: What does Deep Code cost?

There are two tiers. Free is $0 per month and includes session management, the file explorer, snippets, voice input and weekly free credits on DeepSeek-V4-Flash. Pro is $5 per month and adds 100 daily Pro Credits plus bring-your-own-key support for multiple models.

Source
Finxact: Is it genuinely cloud native?

Yes, API first with real time posting on public cloud, rather than a hosted version of a legacy core.

Deep Code: Do I need my own API key to use it?

No. The free tier includes weekly credits and needs no credit card, so the app works without a key. Bring your own key is available on the $5 per month Pro tier and covers DeepSeek-V4-Pro, DeepSeek-V4-Flash, the GLM Coding Plan and the Mimo Coding Plan.

Source
Finxact: How long is a migration?

Plan in years. Even a focused deployment is a multi year programme once integration and data migration are counted.

Deep Code: Which operating systems does it run on?

Windows, macOS and Linux. It is a desktop application rather than an editor extension, so it runs alongside whatever editor you already use.

Source
Deep Code: Is the 95 percent cheaper claim independently verified?

No. It is the vendor's own figure, based on DeepSeek token pricing against frontier model pricing. Actual savings depend on which model you compare against and how much of your usage falls inside the included credits.
