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

Firebase Realtime Database

  • The no-cost Spark plan caps storage at 1 GB, downloads at 10 GB per month and simultaneous connections at 100
  • The Spark plan does not support multiple databases in a project
  • Even on the paid Blaze plan simultaneous connections are capped at 200,000 per database
  • Billing is by data transferred out at $1 per GB plus $5 per GB stored, so chatty clients cost more than the data volume suggests

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
Firebase Realtime Database: How much does Firebase Realtime Database cost?

Firebase Realtime Database offers a free Spark plan (1 GB storage, 10 GB/month downloads) and a pay-as-you-go Blaze plan. On Blaze, storage costs $5 per GB per month, evaluated daily, with no monthly minimum charges.

Source
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
Firebase Realtime Database: What is included in Firebase Realtime Database free tier?

The Spark plan includes 1 GB of data storage and 10 GB per month of data downloads at no cost. Usage within these limits incurs no charges, making it suitable for small projects and testing.

Source
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
Firebase Realtime Database: Does Firebase Realtime Database charge for denied or rejected operations?

Yes. Firebase charges for all traffic to and from the database on the Blaze plan, including operations denied by security rules, outbound network traffic at the session layer, and connection and encryption overhead from all operations.

Source
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
Firebase Realtime Database: Can I set a spending limit on Firebase Realtime Database?

Firebase offers budget alerts but does not cap spending automatically. Users must monitor their usage dashboard in the Firebase console to track connections, storage, downloads, and load metrics; a calculator is available for cost estimation.

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.
