The short version

  • Free plans on both; paid from $5/mo and $10/mo.
  • Only Deep Code lists DeepSeek-backed agent; only Upstash lists serverless Redis.
  • Where Deep Code falls short: the Pro tier caps included usage at 100 Pro Credits per day rather than offering an unmetered plan.
  • Where Upstash falls short: HTTP-based REST API only, no TCP connections means higher latency than self-hosted or connection-pooled Redis.
  • Prices and features on this page 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

Upstash

  • HTTP-based REST API only, no TCP connections means higher latency than self-hosted or connection-pooled Redis
  • Rate limiting occurs when traffic exceeds configured budget cap or request limits
  • Kafka service discontinued in March 2025, requiring migration to Upstash Workflow or alternatives
  • Limited Redis feature support compared to self-hosted Redis or Redis Cloud
  • High-request-volume workloads can accumulate significant costs due to per-request pricing model

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
Upstash: Does Upstash have a free tier?

Yes. The free tier provides 256 MB of data and 500,000 commands per month with 10 GB of bandwidth in a single region, no credit card required.

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
Upstash: How does Upstash work with edge platforms like Vercel and Cloudflare Workers?

Upstash uses a REST API instead of TCP connections, enabling it to work from Vercel Edge, Cloudflare Workers, and AWS Lambda without persistent connections or connection pooling.

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
Upstash: What programming languages are supported?

Upstash provides native SDKs for Python, Node.js, Go, and Rust. Java, C#, and PHP developers can use the REST API or community libraries.

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
Upstash: Is Upstash Kafka still available?

No. Upstash Kafka was deprecated on September 11, 2024 and fully discontinued on March 11, 2025. Upstash Workflow is now recommended for durable serverless messaging and task queuing.

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.

Source
Upstash: How is Upstash pricing structured?

Upstash uses per-request pricing at $0.20 per 100K commands for Redis, $0.25/GB for storage, and $0.40 per 100K requests for Vector database. Idle applications cost nothing.

Source
Upstash: Can Upstash be used with AWS Lambda?

Yes. Upstash works with AWS Lambda via its REST API, eliminating the need for connection pooling and making it ideal for stateless serverless functions.
