Pricing detail. The Turbo and Fast search processors are $1 per 1,000; Basic and Advanced are both $5 per 1,000. The Task API, which is what most agent workloads actually use, runs $5 to $2,400 per 1,000 depending on processor.
Why teams look for a Parallel Search alternative
Parallel is the closest competitor to us by thesis, so the reason for looking is rarely that something is broken. It is usually the Task API: the research-shaped endpoints that most agent workloads end up using are priced on a processor tier, and the spread between the cheapest and the most capable tier is very wide. Teams that started on the cheap search processor and grew into the expensive one see a bill that does not resemble the one they budgeted.
The other reason is control. A research API that does the whole loop is excellent until the loop is the thing you want to own, at which point you are paying for orchestration you have replaced.
Where Parallel Search beats us
They own their index, they are far better capitalised than we are, and their published rate limits are high enough that burst workloads are not a design constraint. For a team whose risk model cares about the vendor still existing in five years, a company with that much funding behind it is a different proposition from a self-funded one, and it would be dishonest to pretend otherwise.

The alternatives
unlob
$0.40/1kWe crawl and index the web ourselves, like the vendor on this page, so there is no upstream provider who can deprecate or reprice us. The index is smaller than the well-funded incumbents, deliberately bounded rather than exhaustive, and the difference in the bill is not marginal. What you get on top is six coverage-graph traversal operations and an endpoint that explains any absence.
Exa
$4/1kNeural, embeddings-first search over a proprietary index, sold alongside content extraction, answers and agentic research products.
Brave Search API
$5/1kA genuinely independent index of 40B+ pages, sold as a conventional search API with an LLM-context option. Long the default independent choice.
Free developer tier removed February 2026
Mojeek
A UK independent crawler and index, running since 2004. Small by comparison, but genuinely its own — and the oldest independent index still standing.
Perplexity
$1/1kRaw web search over its own index through the Search API, and search with synthesis through the Agent API, which replaced Sonar Chat Completions in September 2026.
DataForSEO
$0.60/1kIndustrial SERP infrastructure built for SEO tooling rather than agents. The cheapest per query in the field, with the lowest-level API to match.
Serper
$1/1kThe cheapest way to get raw Google results into an agent. Fast, minimal, and entirely dependent on Google continuing to be scrapeable.
Bright Data
$1.50/1kProxy and unblocking infrastructure with a scraping suite and an agent-facing MCP server. Built for volume collection, priced accordingly.
Linkup
$5/1kA French grounding API returning structured, citation-carrying content for LLMs, with a sub-second "fast" tier and native parallel search.

Frequently asked questions
What is the best alternative to Parallel Search?
It depends what you are replacing. If you need an independent index at the lowest price, unlob is $0.40 per 1,000 searches against $1 for Parallel Search's Turbo processor. If you need the largest possible index, Parallel Search may still be the right tool — we say so on our comparison page rather than pretending otherwise.
Does Parallel Search own its own web index?
Yes — Proprietary web index and retrieval infrastructure. That matters because a provider without its own index inherits the deprecation and repricing risk of whoever it depends on.
How much does Parallel Search cost?
The Turbo and Fast search processors are $1 per 1,000; Basic and Advanced are both $5 per 1,000. The Task API, which is what most agent workloads actually use, runs $5 to $2,400 per 1,000 depending on processor.
