- Asteroid: NOTE — Average. Agents run under your credentials with full visibility. Safety depends on prompt design and credential scope. No explicit guardrails disclosed.
- Winner: Tendem by Toloka. Human review provides stronger safeguards for business-critical outputs. Asteroid's safety profile depends entirely on how you configure agent permissions.
Pricing Deep Dive
| Plan | Tendem by Toloka | Asteroid |
|---|---|---|
| Free Tier | $20 in free credits, no subscription required | No free tier available |
| Entry Paid | Pay-as-you-go per task; no monthly commitment | $30/month (Starter tier) |
| Growth | Undisclosed; scales with task volume | $120/month (Growth tier) |
| Startup | Undisclosed | $300/month (Startup tier) |
| Scale | Custom enterprise pricing | $3,000/month (Scale tier) |
| API Costs | Included in task-based pricing; no separate API billing | Included in subscription tiers |
Tendem by Toloka uses task-based abstraction. You pay per completed task rather than per token or per agent. This model benefits teams with irregular workloads since there is no recurring subscription drain between projects. The $20 free credits allow evaluation without financial commitment.
Asteroid bundles API access into subscription tiers. Higher tiers include dedicated support, higher concurrency limits, and expanded session durations. The $30/month Starter tier requires upfront commitment despite no free trial. Cost scaling is predictable but opaque regarding per-agent pricing at higher volumes.
If budget is the main constraint, pick Tendem by Toloka because the free credits enable hands-on evaluation before any payment decision, and the pay-as-you-go model eliminates waste during low-activity periods.
Real User Sentiment
Community discussions highlight distinct usage patterns for each platform. Data reflects aggregated feedback from developer forums, review platforms, and social channels.
Tendem by Toloka users consistently praise the reliability of delivered outputs. Common themes include satisfaction with customer support responsiveness and the lack of hallucinated content in business documents. Complaints focus on turnaround time, with several users noting that 24-hour delays disrupt time-sensitive campaigns. Non-technical users appreciate the absence of API configuration but report limited visibility into task progress once submitted.
Asteroid users highlight the platform's flexibility for automating repetitive browser tasks. Developers value the SDK documentation and the ability to embed agents into existing CI/CD pipelines. Criticisms center on setup complexity and credential management. Users report that poorly designed prompts yield unpredictable agent behavior, requiring iterative refinement cycles. Some enterprise users note that support response times in lower tiers lag behind expectations during critical deployment windows.
Switching Considerations
Migration from one platform to the other involves meaningful friction. Tendem by Toloka tasks are defined through a web interface without programmatic access. Exporting task logic, workflows, or historical output data requires manual processes. Asteroid uses structured agent definitions and session logs that can be version-controlled, but credential-based authentication means re-authorization flows for each integrated service.
API compatibility is minimal. Tendem by Toloka does not expose a public API, so any integration built on Asteroid cannot leverage existing Tendem workflows without reimplementation. Prompt engineering skills transfer partially since both platforms handle natural language inputs, but agentic behaviors differ significantly.
Cost impact depends on workload profile. Teams switching from Tendem to Asteroid trade human verification overhead for autonomous execution capacity. If current task volumes justify the $30/month minimum on Asteroid, the switch may reduce per-task cost. However, if accuracy errors on Asteroid require manual correction, total operational cost may increase.
The switch is worth it if you have high-volume, low-stakes automation tasks where speed outweighs precision and your team has technical capacity to manage agent configuration and monitoring.
Final Verdict
Choose Tendem by Toloka if:
- Your tasks require verified accuracy where errors carry real business consequences (lead lists, compliance documents, customer-facing chatbots)
- You lack technical resources to configure and maintain autonomous agents and prefer a managed human-in-the-loop workflow
- You need multimodal input handling including Figma files, WhatsApp integration, and structured business data without custom integrations
Choose Asteroid if:
- Your operations involve high-volume repetitive browser tasks across multiple web interfaces that require 24/7 autonomous execution
- You have developer resources to build, deploy, and monitor agent pipelines via SDK and API access
- Data privacy requirements demand that automation runs entirely under your credentials with in-house execution visibility
Neither if:
- Your workload requires real-time responses under one second latency and continuous availability with zero human oversight—these platforms serve different latency and autonomy trade-offs than pure inference services
