OpenClaw Memory Plugins Compared: Contexto vs Mem0 vs Supermemory (2026)

OpenClaw memory plugins give your agent persistent recall across sessions, eliminating the cold start problem where every new session begins with a blank slate. Three plugins currently compete for this job: Contexto, Mem0, and Supermemory. This page compares all three honestly — including where each one wins.

How Do the Three Plugins Compare at a Glance?

How Does Installation Compare?

Contexto

openclaw plugins install @ekai/contexto
# Enter API key when prompted. Done.

One command. No config files. No restart.

Mem0

openclaw plugins install @mem0/openclaw-mem0

Then: open your OpenClaw config file, manually add your Mem0 API key in JSON format, configure memory scopes, set auto-recall/auto-capture flags, and restart OpenClaw. Five distinct steps before memory is active.

Supermemory

openclaw plugins install @supermemory/openclaw-supermemory

Then enter your API key. Then restart the OpenClaw gateway for hooks to register. Two commands plus a forced restart.

How Does Pricing Actually Work?

Contexto: $20/month. That's it. Every feature at one price. No retrieval caps. No usage-based billing. First month free.

Mem0: Starts at $19/month for basic memory. But the advanced feature — graph memory, which builds a knowledge graph of entities and relationships — is locked behind the $249/month tier. That's a 13x price jump to unlock one feature. If you don't need graph memory, the $19 tier works. If you do, $249/month is a steep commitment.

Supermemory: The OpenClaw plugin currently maps to Supermemory's Pro plan at $19/month. The broader platform has higher tiers, but the plugin itself is tied to that entry paid plan.

The cold start tax math: if your time is worth $50/hour and you spend 5 minutes re-briefing your agent each session, that's $125/month in wasted time. All three plugins pay for themselves at the basic tier. The question is which price structure fits your budget and needs.

Where Does Each Plugin Genuinely Win?

Where Contexto Wins

• Simplest install in the ecosystem. One command. No JSON editing. No restart. If you've been burned by complex plugin setups, this matters.
• Local storage by default. Your conversation data stays in a SQLite database on your machine. No cloud servers involved beyond API key validation.
• Flat pricing. $20/month for everything. No tier shock. No feature gates. No per-retrieval charges.
• Built specifically for OpenClaw. Not a general memory platform with an OpenClaw adapter. Every design decision is made for the OpenClaw use case.

Where Mem0 Wins

• Broadest ecosystem. Mem0 works with LangChain, CrewAI, Vercel AI SDK, and more. If you're building across multiple agent frameworks, Mem0 is the only option that spans all of them.
• Graph memory. At the $249 tier, Mem0 offers knowledge-graph-based memory that tracks entities and relationships. Neither Contexto nor Supermemory offers this.
• Open source with a massive community. 24K+ GitHub stars and an active OSS version you can fully self-host with your own infrastructure.
• SOC2 Type II certified. If you need enterprise compliance, Mem0 is the only certified option in this space.

Where Supermemory Wins

• Published benchmarks. Supermemory is the only OpenClaw memory plugin with public benchmark results (MemoryBench). They claim ~30 points higher accuracy than default OpenClaw memory. Neither Contexto nor Mem0 has published comparable benchmarks.
• User profiling. Supermemory builds a profile of the user over time, going beyond conversation recall into behavioral understanding.
• Hooks architecture. Supermemory's architecture hooks into OpenClaw's event lifecycle, which allows finer control over when and how memory operations fire.
• Active founder content. The Supermemory founder posts frequently on YouTube and Twitter, building trust through transparency.

Who Should Choose Which Plugin?

Choose Contexto if:

• You want persistent memory that works in one command with zero configuration
• You care about data privacy and want local-only storage
• You use OpenClaw and only OpenClaw — you don't need cross-framework memory
• You want flat, predictable pricing
• You're a solo founder or indie hacker who values simplicity over feature breadth

Choose Mem0 if:

• You use multiple agent frameworks (LangChain, CrewAI) and need memory across all of them
• You want graph memory for complex relationship tracking (and can justify $249/month)
• You need SOC2 compliance for your organization
• You want to self-host the open-source version with your own infrastructure
• You're building a production system that may scale to enterprise

Choose Supermemory if:

• Published benchmarks matter to your decision-making
• You want user profiling and advanced context engineering features
• You're comfortable with cloud storage and don't need local-only data
• You're building complex multi-agent workflows where hooks-based memory control is important

Choose native OpenClaw memory if:

• Your sessions are short and infrequent
• You don't carry complex context between sessions
• The cold start problem is a mild annoyance, not a productivity drain

Choose DIY (vector DB + embeddings) if:

• You have strong opinions about your vector store and embedding models
• You enjoy infrastructure work and have the time to maintain it
• You want complete architectural control over every component

Frequently Asked Questions

Which OpenClaw memory plugin is the easiest to install?

Contexto installs in one command with no config files and no restart required. Supermemory requires two commands plus a gateway restart. Mem0 requires five steps including manual JSON configuration. For pure ease of setup, Contexto is the simplest.

Is Mem0's free tier good enough for OpenClaw?

Mem0's free tier provides basic memory functionality and works for light usage. The limitations are on retrieval volume and advanced features. If you use OpenClaw daily with complex context, the free tier's caps will become a bottleneck. The paid tier starts at $19/month.

Does Supermemory actually have better accuracy than Mem0?

Supermemory has published MemoryBench results claiming ~30 points higher accuracy than default OpenClaw memory. However, these are self-published benchmarks using their own testing framework. Neither Mem0 nor Contexto has published comparable benchmarks yet, making a direct accuracy comparison difficult.

Can I switch between memory plugins without losing data?

Not automatically. Each plugin stores memories in its own format and location. Switching requires exporting from one plugin and importing to another, if the target plugin supports import. Contexto supports JSON export.

Which plugin is best for privacy?

Contexto stores all data locally in SQLite — your conversations never leave your machine. Mem0's cloud version stores data on their servers, though their OSS version can be self-hosted. Supermemory is cloud-only. For maximum privacy without managing your own infrastructure, Contexto is the strongest option.

Is $20/month for Contexto worth it vs Mem0 at $19/month?

At the basic tier, the prices are nearly identical. The difference is in what happens next: Mem0 jumps to $249/month for graph memory, while Contexto stays at $20/month with no feature gates. If you'll only ever need basic memory, Mem0's $19 is slightly cheaper. If you want everything included at one price with no upgrade pressure, Contexto's $20 is cleaner.

Do any of these plugins work offline?

Contexto works offline after initial API key validation — memories are stored and recalled locally. Mem0 cloud requires an active internet connection for every memory operation. Mem0 OSS works offline if self-hosted. Supermemory requires an internet connection.

Can I use two memory plugins at the same time?

Technically yes, but it's not recommended. Running two memory plugins simultaneously causes duplicate recall injections and conflicting context. Pick one.
