If you run OpenClaw and pay for your own API keys, you have already felt the pain. A busy month with Claude Opus or GPT-4o can cost $500, $1,000, or more. Both claw.zip and Clawzempic exist to fix that. They sit between your OpenClaw instance and your LLM provider, catch every request before it goes out, and decide how to handle it more cheaply.
The question is: which one do you install?
This post compares them honestly. We built claw.zip, so you should know that upfront. But developers see through biased comparisons, and writing one would waste both our time. So here is what each tool actually does, where each one wins, and which type of user should pick which.
The Problem Both Tools Solve
OpenClaw does not have a cost layer. When you send a message, your agent routes it to whatever frontier model you configured, regardless of whether the query needed that model. A simple "what time is it in Tokyo?" hits Claude Opus the same way a complex code review does. You pay Opus prices for Haiku-level work, thousands of times a day.
Both claw.zip and Clawzempic address this by acting as a transparent proxy. You change one line in your OpenClaw config, and every request flows through their system first. The proxy decides how to handle it, then sends the optimized version to your LLM provider. Your OpenClaw experience stays identical. Your bill does not.
That is the shared premise. The implementations diverge from there.
What Clawzempic Does
Clawzempic describes itself as an "inference diet" and is built around three pillars:
Model routing: Clawzempic inspects each query and routes it to the cheapest capable model. Not every message needs a frontier model. This is the same core bet claw.zip makes.
Persistent memory: This is Clawzempic's most distinctive feature. It gives your bots cross-session memory, storing facts, preferences, and corrections so your agents remember context without you managing it manually. For OpenClaw users who run bots across multiple platforms, this is genuinely useful. It is not just a cost feature -- it is a capability upgrade.
Security gateway: Clawzempic includes a gateway that blocks prompt injections, prevents key leaks, and filters dangerous tool calls. No code changes required.
The founder built it to solve his own problem first. He was spending $3,000 a month on OpenClaw inference. After building Clawzempic, that dropped to under $300. The origin story is authentic and the product reflects that.
Clawzempic is a broader bet. It is trying to be the full infrastructure layer for OpenClaw users, not just a cost saver.
What claw.zip Does
claw.zip is narrower on purpose.
Prompt compression: This is the core feature and the one Clawzempic does not explicitly offer. claw.zip compresses your prompts before sending them, removing redundancy and reducing token count without losing meaning. The typical reduction is 78% or more. The model receives a shorter prompt and produces the same output. You pay for fewer tokens on every single request.
Model routing: claw.zip also routes by query complexity. Simple requests go to Haiku, Flash, or Mini. Complex requests go to the model that can actually handle them. Combined with compression, this is where the 80-93% savings figure comes from.
Transparent pricing: Free tier saves up to $50 per month. Pro is $29 per month with unlimited savings and an analytics dashboard. That is it. No contact sales, no "request a quote," no form to fill out before you see a number.
Savings calculator: The homepage has an interactive slider where you enter your current monthly spend and see your projected savings. You know what you are getting before you install anything.
Install takes 60 seconds: npx claw-zip and it patches your OpenClaw config automatically.
Feature Comparison
| Feature | claw.zip | Clawzempic |
|---|---|---|
| Prompt compression | Yes (core feature, -78% typical) | Not explicitly offered |
| Model routing | Yes | Yes |
| Persistent memory | No | Yes |
| Security gateway | Zero-knowledge key architecture | Full security gateway |
| Savings range | 80-93% | 80-90% |
| Public pricing | Yes (Free / $29 Pro) | No pricing page |
| Savings calculator | Yes, on homepage | Not available |
| Install time | ~60 seconds | ~30 seconds |
| OpenClaw-native | Yes | Yes |
A few notes on this table.
The security comparison is not apples-to-apples. Clawzempic runs a full gateway on their side. claw.zip keeps your keys on your machine using zero-knowledge architecture, so you are not trusting a third party with credentials. Different threat models, different approaches. Both are reasonable.
The memory gap is real. claw.zip does not offer cross-session memory. If that is something you actively want for your bots, Clawzempic has it and claw.zip does not.
The pricing transparency gap is also real, in the other direction. There is no public pricing page for Clawzempic. You need to sign up before you see any numbers. That is friction that some users will not bother pushing through.
Where Each Tool Wins
claw.zip wins on:
Prompt compression. This is a unique angle. Reducing token count before the request goes out means you save on every query, regardless of which model handles it. Routing alone skips expensive models for simple queries. Compression plus routing cuts costs at two levels simultaneously.
Pricing clarity. You know what claw.zip costs before you install it. Free gives you up to $50 in monthly savings with no commitment. Pro at $29 is designed to pay for itself on the first few dollars of savings. If you are spending $300 a month on inference, you are saving roughly $240-270 net after the Pro subscription. The math is simple and we show it to you.
Focused scope. claw.zip does one thing: cut your costs. If you want a tool that handles cost reduction cleanly without also reconfiguring your memory and security stack, that simplicity is a feature.
Clawzempic wins on:
Memory. This is not just a cost feature. Cross-session memory makes your bots smarter and less repetitive. If you are running bots that interact with users across days or weeks, Clawzempic's memory layer adds real value that has nothing to do with billing.
Security breadth. The full security gateway addresses prompt injection and key exposure at the infrastructure level. If you are running agents in contexts where security is a primary concern, Clawzempic has more built-in protection.
Feature completeness. If you want one tool that handles routing, memory, and security together, Clawzempic bundles all three. claw.zip is not trying to do that.
Who Should Pick Which
Pick claw.zip if:
You want to cut your OpenClaw bill and nothing else. You have $200-3,000 in monthly inference costs and want to reduce that by 80%+ with a 60-second install and known pricing. You value transparency: you want to see the savings calculator, know what you are paying, and understand the compression ratio before committing. You prefer a tool with a tight scope over a broader infrastructure layer.
The Free tier is a reasonable starting point. If you are spending $300/month, you will see real savings before you ever pay for Pro. When savings exceed $50, the $29 upgrade is obvious math.
Pick Clawzempic if:
Memory is a priority for your setup. If you are running bots that need to remember context across sessions and you do not want to build that yourself, Clawzempic's memory layer is a genuine capability addition. You also want a security gateway bundled in, and you are comfortable with opaque pricing -- meaning you are willing to sign up and find out what it costs before deciding.
The Honest Bottom Line
These are two different bets on what OpenClaw users actually need.
Clawzempic is betting that power users want a full infrastructure layer: cost, memory, and security in one place. It is a broader product aimed at users who want to solve multiple problems with a single install.
claw.zip is betting that most users just want their bill cut, with no surprises, and that prompt compression plus routing does that better than routing alone. Transparent pricing and a savings calculator reflect a specific belief that users deserve to know what they are getting before they commit.
Both approaches are legitimate. The right choice depends on what you actually need from your OpenClaw setup.
If you want to see the numbers before deciding, the claw.zip savings calculator is on the homepage. Enter your current monthly spend and it shows you the projected savings. Install takes 60 seconds: npx claw-zip.
If you are primarily after cross-session memory and a full security bundle, Clawzempic is worth evaluating on its own terms.
Either way, you are paying too much right now. Both tools will change that.
